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
    bool shifted = 0;
    for(int i=0; i<n ; i++){
        shifted = (reg & (1<<7)) >> 7;
        reg <<= 1;
        reg |= shifted & 1;
    }
    return reg;
}

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

Solving Approach

mask and obtain 7th bit and then shift and or into original regsister.
