Extract Even Bits Only from 32-bit Register

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

uint32_t extract_even_bits(uint32_t reg) {
    // Your code here
    //mask shift one to even positions 0 2 4 and And it reg 
    uint32_t res=0;
    for(int i=0; i<32; i+=2){
        if((1U<<i)&reg){
            res = res |(1U<<(i/2));
        }
    }
    return res;
    
    
}

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