I.Q test game help

JemCel03 (10)
Hello everyone! Recently, I tried in some experimentations based on an I.Q Test game. Let me know if there is something I need to improve since this is the first time I made such codes. Basically, this is all about testing one's intelligent from different subjects such as English, Math, and Science.

P.S, this is a very long code and I can't post the upcoming ones so I have to cut it here.

I would recommend breaking this down with functions which are called in your main program.

Example:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28
29
30
31
32
33
34
35
36
37
38
39
40
41
42
43
44
45

#include <iostream>
#include <String>

using namespace std;

string choice;
string CHOOSE1();

int a = 1, b = 2, c = 3, d = 4;

int main()
{
		cout << "Enter a letter a, b, c, or d: \n";

		cout << CHOOSE1();
}

string CHOOSE1()
{
	for (int i = 1; i < 1000; i++)
	{

		cin >> choice;

		if (choice == "a")
		{
			cout << "Input = ";
			cout << " 1 *\n";
		}
		else if (choice == "b")
		{
			cout << "Input = ";
			cout << " 2 **\n";
		}
		else if (choice == "c")
		{
			cout << "Input = ";
			cout << " 3 ***\n";
		}
		else if (choice == "d")
		{
			cout << "Input = ";
			cout << " 4 ****\n";
		}
	}
	return 0;
}


Once it gets the the string of cout << CHOOSE1(); it takes you to the function. Then brings you back once it has ended. Ignore my loop as this was used to help someone else.

By doing it this way, your code will be a lot more neat and organized. Hope this helps.

So, how would this look like if I were to place it on the following questions? I have 5 for easy, 10 for medium, and 10 for extreme.

One function that would shorten the code is a checkAnswer() function:
1
2
3
4
5
6
7
8
 
void checkAnswer(char correctAnswer, char userAnswer)
{
    if (correctAnswer == userAnswer) {
        cout << " You got the correct answer!\n";
    } else {
        cout << "Wrong Answer!\n";
    }
}

Then lines 25-38 become checkAnswer(ans, 'D');. Lines 44-57 become checkAnswer(ans,'C'); etc.

By the way, you don't initialize the characters easy, medium and hard, nor do you tell the user what characters they should enter for each of these.

Once you get this working, consider changing it so that the questions and correct answers are stored in a text file instead of the code. The file might be formatted like this:
- each question consists of:
- a line that gives the difficulty: Easy, Medium or Hard.
- a line that contains one character that is the correct answer.
- N lines that are the question
- a blank line. This signals the end of the question.

The main part of hte program then becomes something like this:
1
2
3
4
5
6
7
 
while (cin >> question) {
  if (question.difficulty == requestedDifficulty) {
      cout << question.text;
      cin >> ans;
      checkAnswer(question.answer, ans);
  }
}

Actually, I was suppose to set the difficulties first before triggering sets of questions, how am I gonna do that anyway?

I might not understand something. It looks like the user selects a difficulty level (diff). Then, depending on what level they selected, the program presents them with different questions. Is that right? To implement this with questions in a file, I'm saying that you mark each question with a difficulty level. If it matches the diff then the program asks that question.
