mcqs pooranay aye thay...
75% paper mein template per hi baat hoi
15% classes n inheritance tha
aur baki ka 10 % mix mein se tha...
so templates ko mostly prepare karen.

Coordinate()
{
X = 0;

}
};
Q2: Write a program that defines a Template function named Square () which finds the square of a number and then return it. Define one variable of type int in main function and then call Square function on that. (10)
Program output should look like this:
Enter an integer value to find its Square: 6
Square of integer number is: 36
Q3: Why is it necessary to initialize a static object as the time of creation and how it is initialized ?(5)
