c语言：Display the capital letters of the alphabet backward from Z to A.

Sure, here's the code to display the capital letters of the alphabet backward from Z to A in C language:

#include<stdio.h>
int main() {
    char ch='Z'; // Start with capital letter Z
    while(ch >= 'A') { // Loop until A is reached
        printf("%c ", ch); // Print the capital letter
        ch--; // Decrement the character value
    }
    return 0;
}

Hope this helps!
