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
    int result = 0;
    int pos = 0;

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

    return result;


}

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