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

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