Write a C++ program that has class

1) math

Math class has only one data member number and member function display that will display the data member number.

Write the constructor of your math class that will initialize the data member number with the value zero.

Program will overload the following operators.

1. Plus +

2. Minus -

3. Multiplication *

After overloading these three operators program will be able to add, subtract and multiply your math class object with the integer in main() after overloading these operators you should be able to write these statements in main().

math obj1, obj2;

obj1= obj2 + 10;

Above statement will call the member function operator + () and will add the 10 in the data member of obj2 and finally will return the math class object. Similarly you also overload the multiplication operator * and minus operator – so that your math class object will be able to multiply and subtract from integer values.

Also your plus + overloaded operator should be intelligent enough to accommodate the following statement in the main() function.

math obj1, obj2;

obj2= 10 + obj1;

for this you will have to write friend function that will be called automatically and will add the integer value 10 in the data member of obj1 and finally will return the math class object . Similarly write two more friend functions that will overload the multiplication and subtraction operator so that you will be able to write the following statement in the main() function.

math obj1, obj2;

obj2= 10 *obj1;

obj2= 10 - obj1;

Your output should be similar to the following:

Sample output 1:

adding integer 10 in the object using statement: obj= obj + 10 ;

10

adding integer 10 in the object using statement: obj= 10 + obj;

20

Multiplying object with integer 20 using statement: obj= obj * 20 ;

400

Multiplying integer 20 with object using statement: obj= 20 * obj ;

8000

Subtracting 20 from object using statement: obj= obj - 20 ;

7980

Subtracting object from 10 using statement: obj= 10 - obj ;
