Extract the Nibble from an 8-bit Register

Solving Approach

How do you plan to solve it?

Code

#include <stdio.h>

unsigned char extractNibble(unsigned char reg, int pos) {
    // Write your code here
    if(pos)
        return reg>>4;
    return (reg & 0b00001111);
}

int main() {
    unsigned char reg;
    int pos;
    scanf("%hhu %d", &reg, &pos);
    printf("%d", extractNibble(reg, pos));
    return 0;
}
