Toggle the Bit in an 8-bit Register

Code

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

#define TOGGLE_REG_BIT(reg, pos) ((reg) ^= (1 << (pos)))

uint8_t toggle_bit(uint8_t reg, uint8_t pos) {
    // Your code here
    return TOGGLE_REG_BIT(reg, pos);
}

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