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 reg_new = 0;
    int pos_new = 0;

    for (int i = 0; i < 32; i+= 2 ){
        reg_new |= ((reg >> i) & 0x1) << pos_new;
        pos_new += 1;
    }
    return reg_new;
}

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