Extract Even Bits Only from 32-bit Register

Code

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

uint32_t extract_even_bits(uint32_t reg) {
    // Your code here
    uint32_t result = 0;
    for (int i = 0; i < 16; i++) {
        // Check if the bit at position 2*i is set in the original register
        if ((reg >> (2 * i)) & 1) {
            // Set the corresponding bit in the result (at position i)
            result |= (1 << i);
        }
    }
    return result;
    return 0;
}

int main() {
    uint32_t reg;
    scanf("%u", &reg);
    printf("%u", extract_even_bits(reg));
    return 0;
}
