Toggle the Bit in an 8-bit Register

Code

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

int toggle_bit(unsigned char reg, int pos) {
    reg ^= (1<<pos);
    // Your code here
    return reg;
}

int main() {
    int reg, pos;
    scanf("%hhu %hhu", &reg, &pos);
    unsigned char result = toggle_bit(reg, pos);
    printf("%u", result);
    return 0;
}
