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 evenReg = 0,n=0;
    for (int i = 0; i <= 30; i += 2) {
        uint32_t extracted_bit = (reg >> i) & 1;
        evenReg |= (extracted_bit << n);
        n++; 
    }
    return evenReg;
}

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