Toggle the Bit in an 8-bit Register

Code

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

uint8_t toggle_bit(uint8_t reg, uint8_t pos) 
{
    // Create a bit mask with a '1' at the specified position and '0's elsewhere.
    uint8_t mask = 1 << pos;
    // XOR the register with the mask to toggle the bit at 'pos'.
    return reg ^ mask;
}

int main() {
    uint8_t reg, pos;
    scanf("%hhu %hhu", &reg, &pos);
    uint8_t result = toggle_bit(reg, pos);
    printf("%u", result);
    return 0;
}
