==>Code goes like this:

#include<stdio.h>
int main()
{
    char ch;
    printf("Enter a character: ");
    scanf("%c",&ch);
    if(ch>64 && ch<91)
    printf("%c",ch+32);
    else
    printf("%c",ch-32);
    return 0;

}

Output:

 







If you are using Turbo C++ IDE, then use conio.h in link section after stdio.h
and use getch(); to hold the output screen, just before the end of main function.
If you have any confusion regarding the program, please, comment below.
Happy Coding !
Thank you
