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
    uint8_t val;
    uint16_t new_val = 0;
    for (uint8_t i = 0 ; i<16 ; i++){
        val = (reg>>2*i) & 0x01;
        new_val |=(val<<i);
    }
    return new_val;
}

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