 T a, b;
 public:
 mypair (T first, T second)
 {a=first; b=second;}
 T getmax ();
 };

 template <class T>

 {
 T retval;
 retval = a>b? a : b;
 return retval;

What happens when we use new and delete operator?

Answer:

When we use new operator to create objects the memory space is allocated for the object and then its constructor

is called. Similarly, when we use delete operator with our objects, the destructor is called for the object before

deallocating the storage to the object.

Q. Suppose a program has a math class having only one data member number.

Write the declaration and definition of operator function to overload + operator for the statements of main function.

         math obj1, obj2;

         obj2= 10 + obj1  ; 

Ans:

#include <iostream.h>

math

{

mth operator + (obj1,obj2)

mth operator + (obj1,obj2)

{

 mth operator + (obj1,obj2)

mth operator + (obj1,obj2)



}

}
