Rotate Left in an 8-bit Register

Code

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

uint8_t rotate_left(uint8_t reg, uint8_t n) {
    // Your code here
    uint8_t i=7;
    while(n)
    {
            if(reg&(1<<i))
            {
                reg=reg<<1;
                reg|=1;
            }
            else
            {
                reg=reg<<1;
                reg|=0;
            }
            n--;
           // i--;
    }
    return reg;
}

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