c++ - Input Validating functions -

i'm new c++ , coding in general. currently, struggling create "mad lib" program asks user inputs (2 different nouns , 2 different adjectives) , uses inputs generate lines " . looks ."

when user runs program, supposed asked "do want play game? enter y yes , n no". if user responds y, madlib function should run , should give inputs. once story finished , returned user, should prompted again whether or not want continue playing (again, y yes , n no). should able play game many times want until answer 'n'. far, last part has been biggest struggle. know how create program within 1 main function, goal make sort of input validation n , y function can called main function. ideas? here's have far:

#include <iostream> using namespace std;  int madlib(){     string noun, adjective, noun1, adjective1;     cout << "enter noun" << endl;     cin >> noun;     cout << "enter adjective" << endl;     cin >> adjective;     cout << "enter noun" << endl;     cin >> noun1;     cout << "enter andother adjective" << endl;     cin >> adjective1;     cout << noun << " " << adjective << ". looks " << adjective1   << " " << noun1 << "." << endl; }  int main(){     char response;     cout << "type y yes , n no" << endl;     cin >> response;     while (response == 'y'){        int madlib();        cout << "play again?" << endl;        cin >> response;     }      if (response == 'n'){        cout << "goodbye." << endl;     } } 

while (response == 'y'){    int madlib(); 

inside while loop, declares function called madlib().

note not same thing executing function called madlib(). declaration. statement of fact exists.

however, proclaiming world, function exists, not sufficient. prefer execute it, instead. in case, be:

    madlib();
