27. Extract Bit Field from 16-bit Register

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

uint8_t extract_field(uint16_t reg) {
    // Your logic here

    int mask = ~0U << 5;
    mask = ~mask;
    mask = mask << 4;
    int value =0;
```
````value =reg & mask;

    value >>=4;
     return value;

 }

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