Question

Im making a simple rock paper scissors game and I need to use the enumeration data structure.
My problem is that i cannot compile the following code because of an invalid conversion from int (userInput) to Throws (userThrow).

enum Throws {R, P, S};
int userInput;
cout << "What is your throw : ";
cin >> userInput;
Throws userThrow = userInput;

Help?!

Answer 1

R, P and S are technically now identifiers for numbers (0,1 and 2, respectively). Your program now does not know that that 0, 1 and 2 once mapped to letters or strings.

Instead, you must take the input and manually compare it to “R”, “P” and “S” and if it matches one, set the userThrow variable accordingly.
