Rotate Left in an 8-bit Register

Code

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

uint8_t rotate_left(uint8_t reg, uint8_t n) {
     n=n%8;
     
       return (reg<<n)|(reg>>(8-n));
}
int main() {
    uint8_t reg;
    uint8_t n;
    scanf("%hhu %hhu", &reg, &n);
    printf("%hhu", rotate_left(reg, n));
    return 0;
}
