Do you have a question?

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

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 ="-------------------------------------------------------------------------------";
