Segmentation Faults Recall what causes segmentation fault and bus errors from lecture. Common cause is an invalid pointer or address that is being dereferenced by the C program. Use the program average.c from the assignment page for this exercise. The program is intended to find the average of all the numbers inputted by the user. Currently, it has a bus error if the input exceeds one number. Load average.c into gdb with all the appropriate information and run it. Gdb will trap on the segmentation fault and give you back the prompt. First find where the program execution ended by using backtrace (bt as shortcut) which will print out a stack trace. Find the exact line that caused the segmentation fault.
Q13. What line caused the segmentation fault?
Q14. How do you fix the line so it works properly?
You can recompile the code and run the program again. The program now reads all the input values but the average calculated is still incorrect. Use gdb to fix the program by looking at the output of read_values. To do this, either set a breakpoint using the line number or set a breakpoint in the read_values function. Then continue executing to the end of the function and view the values being returned. (To run until the end of the current function, use the finish command).
Q15. What is the bug? How do you fix it?
//average.c
#include
/*
Read a set of values from the user.
Store the sum in the sum variable and return the number of values
read.
*/
int read_values(double sum) {
int values=0,input=0;
sum = 0;
printf("Enter input values (enter 0 to finish):\n");
scanf("%d",&input);
while(input != 0) {
values++;
sum += input;
scanf("%d",input);
}
return values;
}
int main() {
double sum=0;
int values;
values = read_values(sum);
printf("Average: %g\n",sum/values);
return 0;
}
Answer:
See Explanation
Explanation:
Q13. Line that caused the segmentation fault?
The segmentation fault was caused by line 15 i.e. scanf("%d",input);
Q14. How the line was fixed?
The reason for the segmentation fault is that the instruction to get input from the user into the integer variable "input" was not done correctly.
The correction to this is to modify scanf("d",input) to scanf("%d",input);
Q15. The bug?
The bug is that the method needs to return two value; the sum of the inputted numbers and the count of the inputted numbers.
However. it only returns the count of the inputted number.
So, the average is calculated as: 0/count, which will always be 0
How it was fixed?
First, change the method definition to: void and also include an array as one of its parameters.
void read_values(double sum, double arr []) {
Next:
assign sum to arr[0] and values to arr[1]
In the main method:
Declare an array variable: double arr [2];
Call the read_values function using: read_values(sum,arr);
Get the sum and values using:
sum = arr[0];
values = arr[1];
Lastly, calculate and print average:
printf("Average: %g\n",sum/values);

Write a program with the total change amount as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies. The input should be an integer, with the unit as "cents". For example, the input of 126 refers to 126 cents. 1 Dollar = 100 cents 1 Quarter = 25 cents 1 Dime = 10 cents 1 Nickel = 5 cents 1 Penny = 1 cent Ex: If the input is:
Answer:
In Python:
cents = int(input("Cents: "))
dollars = int(cents/100)
quarters = int((cents - 100*dollars)/25)
dimes = int((cents - 100*dollars- 25*quarters)/10)
nickels = int((cents - 100*dollars- 25*quarters-10*dimes)/5)
pennies = cents - 100*dollars- 25*quarters-10*dimes-5*nickels
if not(dollars == 0):
if dollars > 1:
print(str(dollars)+" dollars")
else:
print(str(dollars)+" dollar")
if not(quarters == 0):
if quarters > 1:
print(str(quarters)+" quarters")
else:
print(str(quarters)+" quarter")
if not(dimes == 0):
if dimes > 1:
print(str(dimes)+" dimes")
else:
print(str(dimes)+" dime")
if not(nickels == 0):
if nickels > 1:
print(str(nickels)+" nickels")
else:
print(str(nickels)+" nickel")
if not(pennies == 0):
if pennies > 1:
print(str(pennies)+" pennies")
else:
print(str(pennies)+" penny")
Explanation:
A prompt to input amount in cents
cents = int(input("Cents: "))
Convert cents to dollars
dollars = int(cents/100)
Convert the remaining cents to quarters
quarters = int((cents - 100*dollars)/25)
Convert the remaining cents to dimes
dimes = int((cents - 100*dollars- 25*quarters)/10)
Convert the remaining cents to nickels
nickels = int((cents - 100*dollars- 25*quarters-10*dimes)/5)
Convert the remaining cents to pennies
pennies = cents - 100*dollars- 25*quarters-10*dimes-5*nickels
This checks if dollars is not 0
if not(dollars == 0):
If greater than 1, it prints dollars (plural)
if dollars > 1:
print(str(dollars)+" dollars")
Otherwise, prints dollar (singular)
else:
print(str(dollars)+" dollar")
This checks if quarters is not 0
if not(quarters == 0):
If greater than 1, it prints quarters (plural)
if quarters > 1:
print(str(quarters)+" quarters")
Otherwise, prints quarter (singular)
else:
print(str(quarters)+" quarter")
This checks if dimes is not 0
if not(dimes == 0):
If greater than 1, it prints dimes (plural)
if dimes > 1:
print(str(dimes)+" dimes")
Otherwise, prints dime (singular)
else:
print(str(dimes)+" dime")
This checks if nickels is not 0
if not(nickels == 0):
If greater than 1, it prints nickels (plural)
if nickels > 1:
print(str(nickels)+" nickels")
Otherwise, prints nickel (singular)
else:
print(str(nickels)+" nickel")
This checks if pennies is not 0
if not(pennies == 0):
If greater than 1, it prints pennies (plural)
if pennies > 1:
print(str(pennies)+" pennies")
Otherwise, prints penny (singular)
else:
print(str(pennies)+" penny")
The ABC box company makes square puzzle cubes that measure 4 inches along each edge. They shipped the cubes in a box 8 in x 12 in x 16 in. How many cubes can they ship in the box?
Answer: They can ship 32 puzzle cubes in the box.
Explanation: So the volume of each puzzle cubes = side³
=(4)³ cubic inches.
Then the volume of the box is= (8×12×16) cubic inches.
(8×12×16)/4^3= 32

Write a C program that does the following: Creates a 100-element array, either statically or dynamically Fills the array with random integers between 1 and 100 inclusive Then, creates two more 100-element arrays, one holding odd values and the other holding even values (copied from the original array). These arrays might not be filled completely. Prints both of the new arrays to the console.
Answer:
Following are the code to this question:
#include <iostream>//header file
using namespace std;
int main()//main method
{
int axb[100];//defining 1-array of 100 elements
int odd_axb[100], even_axb[100];//defining two array that holds 100-elements
int i,size=0,size1=0;
for(i = 0; i < 100; i++)//defining for loop to assign value in array
{
axb[i] = rand() % 100 + 1;//using rand method to assign value with random numbers between 1 and 100
}
for(i = 0; i < 100; i++)//defining for loop that seprates array value in odd and even array
{
if(axb[i] % 2 == 0)//checking even condition
{
even_axb[size++] = axb[i];//holding even number
}
else//else block
{
odd_axb[size1++] = axb[i];//holding Odd number
}
}
//printing values
cout << "Odd array: ";//print message
for(i = 0; i <size1; i++)//use for loop for print odd numbers
{
cout << odd_axb[i]<<" ";//printing values
}
cout <<"\n\n"<< "Even array: ";//print message
for(i = 0; i <size; i++)//use for loop for print even_axb numbers
{
cout << even_axb[i] << " ";//printing values
}
return 0;
}
Output:
Odd array: 87 87 93 63 91 27 41 27 73 37 69 83 31 63 3 23 59 57 43 85 99 25 71 27 81 57 63 71 97 85 37 47 25 83 15 35 65 51 9 77 79 89 85 55 33 61 77 69 13 27 87 95
Even array: 84 78 16 94 36 50 22 28 60 64 12 68 30 24 68 36 30 70 68 94 12 30 74 22 20 38 16 14 92 74 82 6 26 28 6 30 14 58 96 46 68 44 88 4 52 100 40 40
Explanation:
In the above-program, three arrays "axb, odd_axb, and even_axb" is defined, that holds 100 elements in each, in the next step, three integer variable "i, size, and size1" is defined, in which variable "i" used in the for a loop.
In the first for loop, a rand method is defined that holds 100 random numbers in the array, and in the next, for-loop a condition statement is used that separates even, odd number and store its respective array, and in the last for loop, it prints its store values
Given a HashMap pre-filled with student names as keys and grades as values, complete main() by reading in the name of a student, outputting their original grade, and then reading in and outputting their new grade.Ex: If the input is:Quincy Wraight73.1the output is:Quincy Wraight's original grade: 65.4Quincy Wraight's new grade: 73.1GIVEN TEMPLATES StudentGrades.javaimport java.util.Scanner;import java.util.HashMap;public class StudentGrades {public static void main (String[] args) {Scanner scnr = new Scanner(System.in);String studentName;double studentGrade; HashMap studentGrades = new HashMap(); // Students's grades (pre-entered)studentGrades.put("Harry Rawlins", 84.3);studentGrades.put("Stephanie Kong", 91.0);studentGrades.put("Shailen Tennyson", 78.6);studentGrades.put("Quincy Wraight", 65.4);studentGrades.put("Janine Antinori", 98.2); // TODO: Read in new grade for a student, output initial// grade, replace with new grade in HashMap,// output new grade }}
Answer:
import java.util.Scanner;
import java.util.HashMap;
public class StudentGrades {
public static void main (String[] args) {
Scanner scnr = new Scanner(System.in);
String studentName;
double studentGrade;
HashMap<String, Double> studentGrades = new HashMap<String, Double>();
// Students's grades (pre-entered)
studentGrades.put("Harry Rawlins", 84.3);
studentGrades.put("Stephanie Kong", 91.0);
studentGrades.put("Shailen Tennyson", 78.6);
studentGrades.put("Quincy Wraight", 65.4);
studentGrades.put("Janine Antinori", 98.2);
// TODO: Read in new grade for a student, output initial
// grade, replace with new grade in HashMap,
// output new grade
studentName = scnr.nextLine();
studentGrade = scnr.nextDouble();
System.out.println(studentName + "'s original grade: " + studentGrades.get(studentName));
for (int i = 0; i < studentGrades.size(); i++) {
studentGrades.put(studentName, studentGrade);
}
System.out.println(studentName + "'s new grade: " + studentGrades.get(studentName));
}
}
Explanation:
The program first reads in the entire name (scnr.nextLine()) and the next double it sees (scnr.nextDouble()). In the HashMap, it is formatted as (key, value). studentName is the key, while studentGrade is the value. To get the name when printed, use studentName. To get the grade, use studentGrades.get(studentName).
After, use a For loop that replaces the studentGrade with the scanned Double by using studentName as a key. Use the same print statement format but with different wording to finally print the new grade. Got a 10/10 on ZyBooks, if you have any questions please ask!
write a function insert_string_multiple_times() that has four arguments: a string, an index into the string, a string to insert, and a count. the function will return a string with count copies of the insert-string inserted starting at the index. note: you should only write the function. do not put any statements outside of the function. examples: insert_string_multiple_times('123456789',3,'xy',3) '123xyxyxy456789' insert_string_multiple_times('helloworld',5,'.',4) 'hello....world' insert_string_multiple_times('abc',0,'a',2) 'aaabc' insert_string_multiple_times('abc',0,'a',0) 'abc'
Answer:
Written in Python:
def insert_string_multiple_times(str1,indto,str2,count):
splitstr = str1[:indto]
for i in range(count):
splitstr+=str2
splitstr +=str1[indto:]
print(splitstr)
Explanation:
This line defines the method
def insert_string_multiple_times(str1,indto,str2,count):
In the above definition:
str1 represents the string
indto represents index to insert a new string
str2 represents the new string to insert
count represents the number of times str2 is to be inserted
This gets the substring from the beginning to indto - 1
splitstr = str1[:indto]
This performs an iterative operation
for i in range(count):
This appends str2 to the first part of the separated string
splitstr+=str2
This appends the remaining part of the separated string
splitstr +=str1[indto:]
This prints the new string
print(splitstr)

Package Newton’s method for approximating square roots (Case Study: Approximating Square Roots) in a function named newton. This function expects the input number as an argument and returns the estimate of its square root. The program should also include a main function that allows the user to compute the square roots of inputs from the user and python's estimate of its square roots until the enter/return key is pressed.An example of the program input and output is shown below:Enter a positive number or enter/return to quit: 2 The program's estimate is 1.4142135623746899 Python's estimate is 1.4142135623730951 Enter a positive number or enter/return to quit: 4 The program's estimate is 2.0000000929222947 Python's estimate is 2.0 Enter a positive number or enter/return to quit: 9 The program's estimate is 3.000000001396984 Python's estimate is 3.0 Enter a positive number or enter/return to quit
The python program that calculates the volume and the square of the volume is as follows
radius = float(input("Radius: "))
volume = (4.0/3.0) * (22.0/7.0) * radius**3
sqrtVolume = volume**0.5
print(f'The volume is {volume} units cubed')
print(f'The square root of that number is {sqrtVolume}')
How to write the program?The complete program written in Python where comments are used to explain each line is as follows
This gets the radius
radius = float(input("Radius: "))
#This calculates the volume
volume = (4.0/3.0) * (22.0/7.0) * radius**3
#This calculates the square root of the volume
sqrtVolume = volume**0.5
#This prints the volume
print(f'The volume is {volume} units cubed')
#This prints the square root of the volume
print(f'The square root of that number is {sqrtVolume}')
Therefore, The python program that calculates the volume and the square of the volume is as follows
radius = float(input("Radius: "))
volume = (4.0/3.0) * (22.0/7.0) * radius**3
sqrtVolume = volume**0.5
