Question

I have a pretty simple question. Is there a way to dynamically shift bitwise to the left OR to the right, e.g. depending on the sign of an int.

signed int n = 3;
signed int m = -2;

int number1 = 8;
int number2 = 8;

//number1 shift n;
//number2 shift m;

In this case I want to shift number1 3 bits to the left and number2 2 bits to the right. Is there a way without if else?

Answer 1

Does ?: count as an if-else ?

int x = (n > 0) ? (number1 << n) : (number1 >> (-n));
int y = (m > 0) ? (number2 << n) : (number2 >> (-m));
