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 temp = 0;
    int bit_pos =0;
    for (int i =0; i< 32; i+=2){
        int val = (reg >> i) & 1;
        temp |= (val << bit_pos);
        bit_pos++;
    }
    return temp;

}

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