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

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