what is your question?

[Lucaci Andrew]

what is your question?

As if you read my mind.

Beside posting this long code, what seems to be the problem?
I see you use these:

#include<iostream.h>
#include<conio.h>

There are some topics related to that of using conio.h.
And in C++ nowdays it's <iostream> not <iostream.h>

[Schol-R-LEA]

In the absence of the necesary information from the OP, I can only make broad suggestions, with the number one recommendation being to replace all of these repetitive tests with a table and simple loop.

struct Q_and_A 
{
    std::string question;
    std::string options[3];
    char answer;
    int points;
};

Q_and_A exam[] = {
    {"What is called 'THE HOLY LAND'?", {"Jerusalem", "Mathura", "Mecca"}, 'a', 10},
    {"What is called 'THE ROOF OF THE WORLD'?", {"Nepal", "Rome", "Tibet"}, 'c', 10},
    // and so on ...
    {"What is called 'THE DARK CONTINENT'?", {"Asia", "Australia", "Africa"}, 'c', 10}
};

// later, in the program code...

for (int i = 0; i < 10; i++)
{
     char answer;

     std::cout << std::endl << "Q" << i <<". " << exam[i].question << std::endl;
     for (int j = 0; j < 3; j++)
     {
         std::cout << ('a' + (char) j) << ". " << exam[i].option[j] << std::endl;   
     }
     cin >> answer;
     if (answer = exam[i].answer)
     {
         x += exam[i].points;
         std::cout << "\nGood Job.";
         std::cout<<"\n Your score is " << x << std::endl;
     }
     else
     {
         std::cout << "\n Sorry wrong answer." << std::endl;
     }
}

I don't know if this solves the problem you were posting about, but I'll bet it solves a lot more than just that.
