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
int mask = 1<<pos;
if(mode == 1)
{
   
    reg = reg | mask;
}
else
{

reg = reg & ~mask;
}

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;
}
