I have to add "invalid answer try again" to my C++ code. Can someone help me out? Here is my code so far. I need to be able to allow the user to correct their answer if they choose wrong in multiple choice and for true/false. I have also included the assignment details to help clarify anything I missed.

Write a C++ program to allow the user to create a test bank of questions. The program should first ask the user how many questions he or she wishes to create. This quantity will be the first line in the test bank. The user should now be prompted for all information for each question, and then that question is written out to the test bank in the exact format specified in the Phase 2 Individual Project.

For each question, the following information should be gathered:

Question type: Multiple choice (MC) or True/False (TF)

Question value

Actual question

If the question is TF, then get answer

If the question is MC, then get the number of options followed by each option and finally the answer

***********This program should be robust and allow users who make mistakes the ability to correct them (exception handling).*************

This is where I'm stuck. The sentence in BOLD.

#include #include #include #include #include #include #include #include #include #include #include #include

using namespace std;

int main() { ofstream outFile; outFile.open ("testbank.txt"); // A text file 'testbank.txt' will be created or opened in the same directory of the .cpp file

int totalQuestion; string option, type, question, answer; int totalOptions;

try{

cout << "Welcome to Michael's Quiz. Enter total number of questions: "; cin >> totalQuestion;

outFile << totalQuestion << endl;

for (int i = 0; i < totalQuestion; ++i) { cout << " Question " << (i+1) <> type;

if(type == "TF") { cin.ignore();

cout << "Enter the question : "; getline(cin,question);

cout << "Enter the answer(True/False): "; cin >> answer;

outFile << type << endl; outFile << question << endl << answer << endl; }

else if(type == "MC") { cin.ignore();

cout << "Enter the question : "; getline(cin,question);

cout << "Enter the number of options for the question : "; cin >> totalOptions;

outFile << type << endl; outFile << question << endl;

cin.ignore(); /* This line should be out of the loop so that we don't have to press Enter twice */

for (int j = 0; j < totalOptions; ++j) { cout << "Enter option number " << (j+1) <<" : "; getline(cin , option); outFile << option << endl; }

cout << "Enter the correct answer : "; cin >> answer; outFile << answer << endl; }

else { throw "Wrong type of Question"; // Exception Handling }

} }

catch(const char* msg) // Catch Block to handle the exception { cerr << msg << endl; }

outFile.close(); return 0;

} /* output:
