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;

    for(int i = 31;i>=0;i--){
        if(!(i&1)){
            if((reg >> i) & 1){
                result = (result | 1 ); 
            }
            result = result << 1;
        }
    }
    return result>>1;
    above method works but dont use this method
    */
    uint32_t result = 0;
    int out_pos = 0;

    for (int i = 0; i < 32; i += 2) { // iterate over even positions
        uint32_t bit = (reg >> i) & 1;
        result |= bit << out_pos;
        out_pos++;
    }

    return result;
}

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