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

        }
        out_pos ++;
        
    }
    return result;
}

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