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 count=0,num=0;
    for(int i=0;i<32;i++){
        if(i%2==0){
            int p=((reg>>i)&1)<<count;
            num|=p;
            count=count+1;
        }
    }
    return num;
}

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