How do I get a char from a hex code stored in a character pointer in C?

Question

How can I get a char in C that corresponds with a hex code stored in a character pointer?

For example, in the below, I have "2A" in char pointer hex. How do I get the * character from this?

int main() {  
char* hex = "2A";

return 0;
}

Have you tried strtol?

#include <stdio.h>
#include <stdlib.h>

int main () {
    char *hex = "2A";
    printf("%c\n", (int)strtol(hex, NULL, 16));

    return 0;
}
