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

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