5. Clear the Bit in an 8-bit Register

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

uint8_t clear_bit(uint8_t reg, uint8_t pos) {
    // Your code here
    int mask = 1<<pos;
    if((reg & mask) != 0) // bit is set to 1 lets clear it
    {
        reg &= ~(1<<pos);
        return reg;
    }
    return reg;// this means it is already set to 0
}

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