Extract Bit Field from 16-bit Register

Code

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

uint8_t extract_field(uint16_t reg) {
    // Your logic here
    int mask=0,mask1=0;
    mask=reg | mask;
    mask=mask>>4;
    mask1=(1<<5)-1;
    mask=mask & mask1;
     
    return mask;
}

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