Set or Clear a Specific Bit in a Register

Code

#include <stdio.h>

unsigned char modifyBit(unsigned char reg, int pos, int mode) {
    // Write your code here

if(mode) {

    reg = reg |(1<< pos);

    return reg;
}
else if (mode == 0){

  reg = 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;
}
