Extract Bit Field from 16-bit Register

Code

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

uint8_t extract_field(uint16_t reg) {
    // Your logic here
    return (reg>>4)&0x1F;
}

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

Solving Approach

reg >>= 4;              // Shift bits 4–8 to positions 0–4
return reg & 0x1F;      // Mask lower 5 bits to extract the field
