Toggle the Bit in an 8-bit Register

Code

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

/**
 * Function to toggle a specific bit in an 8-bit register
 * 
 * @param reg: the original 8-bit register value
 * @param pos: the position of the bit to toggle (0-indexed)
 * @return: the modified register value with the specified bit toggled
 */
uint8_t toggle_bit(uint8_t reg, uint8_t pos) {
    return reg ^ (1 << pos);
}

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