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
    int outBit = 0;
    uint32_t result = 0 ;
    for(int i = 0; i < 32; i++) {
        if(i % 2 == 0) {
            out |= (((reg >> i) & 1) << outBit++);
        }
    }
    return out;
}

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