Question

Okay, I have an if sentence in which I compare a specific value multiple times. I bet there is a shorter way to do this:

if(letter == "%" || letter == "+" || letter == "-" || letter == "!")

I tried writing it as:

if(letter == "%" || "+" || "-" || "!")

But it works incorrectly.

Answer 1

Something like this might work:

string s("%+-!");
if (s.find(letter) != string::npos) { ... }
