Extract Even Bits Only from 32-bit Register

Code

#include <stdio.h>
#include <stdint.h>

uint32_t extract_even_bits(uint32_t reg) {
    uint32_t result = 0;
    int new_pos = 0;  

    for (int i = 0; i < 32; i++) {  
        if (i % 2 == 0) {  
            uint32_t bit = (reg >> i) & 1;  
            result |= (bit << new_pos); 
            new_pos++;  
        }
    }

    return result;
}

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