C++ coding hw Part A. Code a for loop to print the Celsius temperatures for Fahr

Question

C++ coding hw

Part A. Code a for loop to print the Celsius temperatures for Fahrenheit temperatures 25 to 125. C = 5/9(F – 32). Output should be in a table format:

Fahrenheit Celsius

25 degrees

. .

. . . .

. .

Turn in the source and the output from Part A.

Part B. Code a while loop to read in and total any number of positive integers terminated with a -1 as a sentinel. Print the average of the values after the loop is finished. Run with at least 4 or 5 numbers – make some of them negative numbers which should not be included in the total or average. The approach should be:

1. Define total and count and set them to 0

2. Read in a number

3. While number != -1

3.1 If number >0

3.1.1 Total += number

3.1.2 Count ++

3.2 Read in another number

4. Print the average of the positive numbers

5. Stop

Turn in the source and the output from Part B.

Part C. Code a do while loop to make change for a customer. Input the amount of money put into a vending machine. Change that value to cents. Input the amount of the purchase. Change that value to cents. Subtract the two values. Determine the customer’s change in number of quarters, dimes, nickels, and pennies, using integer arithmetic. Hint:

cents / 25 = number of quarters

cents % 25 = remaining cents to change into dimes, nickels, etc.

Keep making change for different purchases until the user tells you to stop. Make change for 3 or 4 purchases. Turn in the source and 3 or 4 outputs from Part C.

Explanation / Answer

Given below is the code for the different parts. Please do rate the answer if it helped. Thank you.

partA.cpp

#include <iostream>
using namespace std;
int main()
{
double C;
  
cout << "Farenheit Celsius" << endl;
for(double F = 25; F <= 125; F += 1) //change F from 25 to 125 in steps of 1
{
C = 5.0 / 9 * (F - 32); //calculate C based on value of F, use 5.0 instead of 5, to perform double division
cout << F << " " << C << endl; //display F and C
}
}

output
