count_char.c

#include <stddef.h>

size_t count_char(const char *s, char c) {
    /* write this */
}

Implement count_char: return how many times c appears in the NUL-terminated string s.

Reference 
size_t count_char(const char *s, char c) {
    size_t n = 0;
    for (; *s; s++) {
        if (*s == c) n++;
    }
    return n;
}

Walk the string once, comparing each byte before the loop advances past it.
