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 new_val=0;
    int i=0,j=0;
    for(int i=0;i<=31;i=i+2)
    {
        if( reg>>i&1)
        {
            new_val|=(1<<j);
            j++;
        }
    }
   return new_val;
}
int main() {
    uint32_t reg;
    scanf("%u", &reg);
    printf("%u", extract_even_bits(reg));
    return 0;
}
