Rotate Right in a 32-bit Register

Code

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

uint32_t rotate_right(uint32_t reg, uint8_t n) {
    // Your code here
    uint32_t tmp=0;
    uint8_t cnt=0;
    while (cnt<n){
      tmp=(reg&0x01);
      reg>>=1;
      
      reg|=tmp<<31;
      
      cnt++;
    }
    
    return reg;
}

int main() {
    uint32_t reg;
    uint8_t n;
    scanf("%u %hhu", &reg, &n);
    printf("%u", rotate_right(reg, n));
    return 0;
}
