Question:
I can’t seem to get the switch statement to work with chars.For example:
#includechar answer[2];void main(){ cout << "Enter your answer: "; cin >> answer; switch(answer) { case 'a' : cout << "blah"; break; case 'b' : cout << "blah blah"; break; case 'c' : cout << "blah blah blah"; break; case 'd' : cout << "blah blah blah blah"; break; }}
Trying to compile this would give me an error saying that the “switch expression of type ‘char [2]’ is illegal” and that it requires an “integral expression”.
Answer:
Your compiler is trying to tell you that you can’t use an array (or any other non-integral data type) in a switch statement. Either change your declaration of the variable answer to:
char answer; // a single char
Or, if you need an array, use if statements instead of a switch.
