C++ signs as variable?

Is there a way to make a variable with the value of a sign like + or - ?

char a = '+'; if(a == '+') cout << a << endl;

Yes, but how can we compare the value when we can't even create a variable named + or - ? int + = 5; // doesn't work int a = 5; // works if(a == +) // + is not variable Tell me if I misunderstood you.

Yes char variables are what you need.

Valid variable name should begin with letter or underscore, followed by mixture of letters (uppercase or lowercase), underscore or number (in no distinct sequence). Symbolic character such as + or - are not qualified to form a variable name, nor to be part of a variable name. This is as I understand it.

Ipang I mean as the value for the variable like how you would say int a = 2 or float b = 4. I’m wondering if there is something i could do to make the value a + or -

Just in case someone doesn’t understand it would be something like “if (variable name == +) {cout << variable name}
