1. Set or Clear a Specific Bit in a Register

#include <stdio.h>

unsigned char modifyBit(unsigned char reg, int pos, int mode) {
    // Write your code here
    //1. Check if we want to set/clear bit
    //1.1 If mode = true(1) we want to set a bit
    if(mode){
        reg |= (1<<pos); //Shift 0001 into the correct position & OR to set
    }
    else{
        reg &= ~(1<<pos);
    }
    return reg;
}

int main() {
    unsigned char reg;
    int pos, mode;
    scanf("%hhu %d %d", &reg, &pos, &mode);
    printf("%d", modifyBit(reg, pos, mode));
    return 0;
