Question
C++ help to make Multiple choice function for testbank file I/O program. I made the function I just need help figuring out how to do the choices for it. Below is my code and the pseudo code to assist.
Pseudocode:
If MC question, then
i. Ask how many points the question worth.
ii. Enter the question. iii. Ask home many options, say OP
iv. Loop 1 to OP
1a. Enter the option.
2a. Repeat step iv until reaches value OP
v. Enter the answer to the question.
The output stored in the file for the MC should look like this example (I did not include the TF this is only selecting MC what it should look like):
MC 10
Who was the President of the USA in 1991?
6
Richard Nixon
Gerald Ford
Jimmy Carter
Ronald Reagan
George Bush Sr.
Bill Clinton
E
My code:
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
class TestBank
{
public:
void TrueFalse(ofstream&);
void MultipleChoice(ofstream&);
};
int main()
{
TestBank bankObj;
ofstream test;
int testNumber, typeOfQuestion;
char yesOrNo;
// Create test bank file.
test.open("C:\temp\testBankFile.txt");
if (test.is_open())
{
cout << "How many questions would you like to create? ";
cin >> testNumber;
test << testNumber << endl;
int nextNum = 1;
//create the test bank
for (int i = testNumber; i > 0; --i)
{
cout << endl << "What type of question will #" << nextNum++
<< " be? 1=T/F or 2=multiple choice: ";
cin >> typeOfQuestion;
if (typeOfQuestion == 1)
test << "TF ";
else if (typeOfQuestion == 2)
test << "MC ";
else
cout << "Invalid option" << endl;
switch (typeOfQuestion)
{
case 1: bankObj.TrueFalse(test);
break;
case 2: bankObj.MultipleChoice(test);
}
}
test.close();
}
else
{
cout << "Unable to create test bank";
}
system("pause");
return 0;
}
// function to create true/false question
void TestBank::TrueFalse(ofstream& thefile)
{
int points;
string question;
string answer;
char yn;
do
{
cout << " How many points does this question worth? Enter: ";
cin >> points;
cin.ignore();
cout << " Please enter the question: ";
getline(cin, question);
cout << " Please enter the answer True or False ? ";
cin >> answer;
cin.ignore();
cout << "Would like to make any correction <y/n>? ";
cin >> yn;
} while (yn == 'y');
//Write all information into the file
thefile << points << endl;
thefile << question << endl;
thefile << answer << endl;
}
//Now you have to complete function MultipleChoice()
// function to create multiple choice question
void TestBank::MultipleChoice(ofstream& theFile)
{
}
I also need to make the program read in the file after all information is collected to display out the collected information from the file. The result should look like this:
This means the output file would look like this:
3
TF 5
There exists birds that cannot fly?
true
MC 10
Who was the President of the USA in 1991?
6
Richard Nixon
Gerald Ford
Jimmy Carter
Ronald Reagan
George Bush Sr.
Bill Clinton
E
TF 10
The city of Boston hosted the 2004 Summer Olympics?
false
Please assist me with primarily the MC function located at the bottom of the code. Second, displaying the results before exiting the program from the data saved to the file from the program read back in.
