Rotate Left in an 8-bit Register

Code

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

uint8_t rotate_left(uint8_t reg, uint8_t n) {
    for(int i=0;i<n;i++){
        int temp = 0;
        temp|=(1<<7);
        temp = temp&reg;
        temp = temp>>7;
        reg = reg<<1;
        reg |= temp;

    }
    return reg;
}

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