Question

In C Write a program that

1. prompts the user to enter a Fahrenheit temperature
2. calculate the corresponding temperature in Celsius and print it
3. prompt the user if they want to do another temperature conversion
4. if the user enters y, repeat 1), 2) and 3)
5. if the user enters n, then print Bye and exit the program
6. if the user enters any other character, ask the user to enter y or n only

Note : c = (5.0/9.0)*(f-32.0)

Sample output

Enter temperature in deg F

50

You entered 50 def F. The corresponding temp in deg C is 10.00

Another temperature conversion?

Enter y or n please

y

Enter temperature in deg F

60

You entered 60 def F. The corresponding temp in deg C is 15.56

Another temperature conversion?

Enter y or n please

a

Enter y or n please

#

Enter y or n please

y

Enter temperature in deg F

70

You entered 70 def F. The corresponding temp in deg C is 21.11

Another temperature conversion?

Enter y or n please

n

Bye

Answer 1

Here is the complete c code with comments to understand everything:

//Inlcuding the required header files
#include <stdio.h>
#include <stdlib.h>
int main()
{
    //tempinF is a float value so that decimals can be displayed
    float tempInF;
    //Initially we keep the choice value a 'y' so that we can enter the loop
    char choice = 'y';
    while (choice == 'y')
    {
        printf("Enter temperature in deg F\n");
        scanf("%f", &tempInF);
        /*we use %0.02f so that only 2 decimal places are displayed, 
        the formula as given in the question is applied to get the temperature in deg C*/
        printf("You entered %0.02f def F. The corresponding temp in deg C is %0.02f", tempInF, (5.0 / 9.0) * (tempInF - 32.0));
        printf("\nAnother temperature conversion?\nEnter y or n please\n");
        /*getchar() is used here to clear the buffer, to better understand why it
        is used try removing it and see what happens, then you will better understand 
        why it is used*/
        getchar();
        //Get the choice from the user
        scanf("%c", &choice);
        /*If the choice is n simply say bye and exit*/
        if (choice == 'n')
        {
            printf("Bye\n");
            exit(0);
        }
        /*Otherwise if the choice is not y then keep asking for a valid input until the
        user inputs 'y' or 'n'*/
        else if (choice != 'y')
        {
            while (choice != 'y' && choice != 'n')
            {
                getchar();
                printf("Enter y or n please\n");
                scanf("%c", &choice);
            }
            if (choice == 'n')
            {
                printf("Bye\n");
                exit(0);
            }
        }
    }
}
