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 extracted_data = 0;
    for(int i=0;i<16;i++){
        uint8_t bit = ((reg >> (i*2))&1);
        extracted_data = extracted_data  | (bit << i);
    }
    return extracted_data;
    
}

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