Hints

Move the pointer itself with s++ instead of using an index.

Solution explanation

The parameter s is a local copy of the pointer, so moving it doesn't affect the caller.

#include <stdio.h>
#include <string.h>

int count_char(char *s, char c) {
    int n = 0;
    while (*s != '\0') {
        if (*s == c) n++;
        s++;
    }
    return n;
}

int main() {
    char s[200], c;
    fgets(s, 200, stdin);
    s[strcspn(s, "\n")] = '\0';
    scanf(" %c", &c);
    printf("%d\n", count_char(s, c));
    return 0;
}
