Question

Before and After

by CodeChum Admin

The only constant thing in the world is change. That’s why we need to call the toupper() function to change what we already have into a better version.

Instructions:

1. Your task is to ask the user for a character input.
2. Then, include the ctype.h built-in library and call the toupper() function. In case you do not know what this function is, this function has the following definition:
3. Return type - int
4. Name - toupper
5. Parameter - one integer which represents the ASCII of a character
6. Description - returns the ASCII of the uppercase equivalent of the character passed
7. Extra note - even though it's function definition in the C Programming Language Documentation is int toupper(int ch), you can just pass a normal char variable instead and this will just be automatically typecasted/converted to its integer equivalent.
8. Once you get the uppercase equivalent, print this out.

Input

1. Letter to be updated

Answer 1

#include <stdio.h>
#include "ctype.h"

int main()
{
    char ch;
        
    printf("Enter char: ");
    ch = getchar();
    getchar();
    printf("\nUppercase equivalent: %c", toupper(ch));  
}
