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 res=0;
   int  out_pos=0;
    for(int i=0;i<32;i+=2){
//checking if 1 then only go inside the loop where 1 is shifted according to the position
if(reg>>i&1==1){
res|=1<<out_pos;
}
out_pos++;
    }
    return res;
}

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