Question

This is the code I am going to use to take a set of three booleans and convert it into an int for a switch statement:

int bits = 0;
bool a = true, b = false, c = true;  // 101 = 5

bits = bits | a << 2;
bits = bits | b << 1;
bits = bits | c;

cout << bits;

I have eight cases based on the combined state of these three booleans. Am I doing this right?

Right, not in the sense of the syntax although if there are any problems there please advise. More right in the sense of “Is this the best way to solve this problem?”

Answer 1

If you are using C++, you could use bitset<N>.
