    //This is the only way I know that when a question is been asked it uses the statements below try it out.Only "Grade 1"I repeat Grade 1 only works at the moment for this is still a prototype.I am new to programming please bear with me.Thanks.

    Re: Question and Answers Program

    Do you have a question?

    If you want help with code, you'll need to use code tags and proper formatting.

    Re: Question and Answers Program

    As GCDEF said, please use code tags when posting code. The code as posted is just about unreadable. Go Advanced, select the code and click '#'.

    Code:
    int grade1q1(void)
    {
    int a1 = 0,
         a2,
         guessNum;
    
         cout << "\n\nQuestion No.1\n\n";
        do
        {
            for (guessNum = 0; a1 != 1; guessNum++) 
            {
                 if (guessNum < 5) 
                 {
                      {
                            cout << "\n_____ you going to school?";
                            cout << "\n\n[1]Are [3]Is\n\n[2]They [4]Will\n";
                            cin >> a1;
                      }
                } 
                else 
                {
                      cout << "Thank you for using the program.";
                      return 0;
                }
           }
        } while (a1 != 1);
    }
    The extra braces highlighted are not needed.
    Code:
    using namespace std;
    using std::string;
    You don't need to have using std::string as you already have using namespace std.

    Code:
    case 1:cout<<space<<line<<"\nGrade 1";cout<<grade1q1();cout<<grade1q2();cout<<grade1q3(); break;
    I would advise against having more than one statement per line
    Code:
    case 1:
         cout << space << line <<" \nGrade 1";
         cout << grade1q1();
         cout << grade1q2();
         cout << grade1q3();
         break;
    Code:
    string space ="\n\n\n\n\n\n\n\n\n\n\n\n\n";
    string line ="-------------------------------------------------------------------------------";
    As the value of these variables doesn't change, they would usually be defined as const.
    Code:
    const string space ="\n\n\n\n\n\n\n\n\n\n\n\n\n";
    const string line ="-------------------------------------------------------------------------------";
