Rotate Left in an 8-bit Register

Code

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

uint8_t rotate_left(uint8_t reg, uint8_t n) {
    int i;
    for(i = 0; i < n; i++){
        uint8_t msb = reg & 0x80;
        reg = reg << 1;
        if(msb){
            reg |= 0x1;
        }
    }
    return reg;
}

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