use C program Enter a string, count and output the number of capital consonants in the string (capital consonants: capital letters except A, E, I, O, U). 【Input】 Enter a character string. 【Output】 Output the number of uppercase consonants.

Sure, here's a C program that asks the user to input a string and counts the number of capital consonants (capital letters except A, E, I, O, U) in the string:

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

int main() {
    char str[100];
    int i, count=0;

    printf("Enter a string: ");
    fgets(str, 100, stdin);

    for(i=0; str[i]!='\0'; i++) {
        if(isupper(str[i]) && str[i]!='A' && str[i]!='E' && str[i]!='I' && str[i]!='O' && str[i]!='U') {
            count++;
        }
    }

    printf("Number of capital consonants: %d\n", count);

    return 0;
}

The program first declares a character array `str` of size 100 to store the user input. It then prompts the user to enter a string using the `printf()` function and reads the input using the `fgets()` function.

The program then loops through each character in the string using a `for` loop. For each character, it checks if it is an uppercase letter using the `isupper()` function, and also checks if it is not one of the vowels A, E, I, O, or U. If both conditions are true, then the program increments the `count` variable by 1.

Finally, the program prints the number of capital consonants using the `printf()` function.

I hope this helps! Let me know if you have any questions.
