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 temp=0;
    uint8_t i=0;
    for(i=0;i<32;i++)
    {
        if(!(i%2))
        {
            temp |= (reg&(1<<i))>>(i/2);
        }
        
    }
    return temp;
}

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