Answer 1

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

int match(const char *string, const char *pattern) {
    regex_t regex;
    int result;

    regcomp(&regex, pattern, 0);
    result = regexec(&regex, string, 0, NULL, 0);
    regfree(&regex);

    return result == 0;
}

int main() {
    printf("%d\n", match("bud", "b.d"));
    printf("%d\n", match("bid", "b.d"));
    printf("%d\n", match("bed", "b.d"));
    printf("%d\n", match("b d", "b.d"));
    printf("%d\n", match("bat", "b.d"));
    printf("%d\n", match("bd", "b.d"));
    printf("%d\n", match("bead", "b.d"));

    return 0;
}
