char hex[] = "6A";                          // here is the hex string
int num = (int)strtol(hex, NULL, 16);       // number base 16
printf("%c
", num);                        // print it as a char
printf("%d
", num);                        // print it as decimal
printf("%X
", num);                        // print it back as hex
