Write a class called  Adder that stores the sum of all the  ints given to it. Your  Adder class should allow you to write the following code (and code like it):

// sample code

Adder sum1;      // sum1 is initialized to 0

Adder sum2(2);   // sum2 is initialized to 2

cout << "sum1 is " << sum1 << 'n';     // prints "sum1 is 0"

cout << "sum2 is " << sum2 << 'n';     // prints "sum2 is 2"

sum1 += 5;   // adds 5 to sum1; now sum1 is 5

sum2 += -3;  // adds -3 to sum2; now sum2 is -1

if (sum1 == sum2)  

cout << "sum1 and sum2 are the samen";

You should only write the functions that are necessary for   Adder to be used as in the above program. Use const wherever appropriate, and do  not write or use a cast operator. Make sure to include any necessary header files.
