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,pos= 0;
    for(uint32_t i=0;i<32;i+=2)
    {
        if(reg>>i & 1)
        {
            result= result|(1<<pos);
        }
        pos++;
    }

    return result;
}

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