Extract Bit Field from 16-bit Register

Code

#include <stdio.h>
#include <stdint.h>

uint8_t extract_field(uint16_t reg) {
    reg = (reg>>4)&0xFF;
    reg <<= 11;
    reg >>= 11;
    return reg;
}

int main() {
    uint16_t reg;
    scanf("%hx", &reg);
    printf("%u", extract_field(reg));
    return 0;
}
