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

    uint16_t val =0;
    int pos=0;

    for(int i=0;i<32;i+=2){
        uint16_t bit = (reg>>i) & 1;
        val |= (bit<<pos);
        pos++;
    }

    return val;
}

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