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;
    int new_pos = 0;

    for (int i = 0; i < 32; i += 2) {
        if (reg & (1U << i)) {
            result |= (1U << new_pos);
        }
        new_pos++;
    }
   return result; 
}

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