Rotate Left in an 8-bit Register

Code

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

uint8_t rotate_left(uint8_t reg, uint8_t n) {
    char bit=0;
    for(int i=0;i<n;i++)
    {   
        if(reg & 1<<7) bit=1;
        reg <<= 1;
        if(bit) reg|= 1<<0,bit=0;
    }
    return reg;
}

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