Question

C++

Define an Investor class that has the following member variables and functions:

Two (2) private member variables:

A double array of size 10 that stores investment dollar amounts for 10 companies;

An int variable that stores the number of gains.

Three (3) overloading operators as member functions:

The unary operator ++ increments the number of gains

The unary operator += n increments all 10 investment amount by n dollars

The binary operator [ ] returns an element of the investment array (return type: double)

Four (4) overloading operators as friend functions:

The binary operator + adds the investment arrays, element by element, and the number of gains for two investors

The binary operator > compares the total investment amounts, and the number of gains of two investor objects (return type: bool)

The binary operator >> inputs the investment array and the number of gains (return type istream&)

The binary operator << outputs the investment array and the number of gains (return type ostrean&)

In the main, create at least three investor objects. Test all operators you created, namely,

Input two investors (>>)

Compare the two investors (>) to determine which investor has a better performance

Merge two investors by adding the two investors (+)

Increment number of gains for investors (++)

Append investment amount for investors (+=)

Access investment amount for a particular company ([ ])

Output investors (<<)

   }
   operator +=(int n)
   {
       for(int i=0;i<10;i++)
       {
           amount[i]=amount[i]+n;
       }      
   }
   double operator [](int i)
   {

   }      
   operator +(Investor& inv1)

       }
       else
       return false;
