Write a class named Accumulator containing: An instance variable named sum of type integer. A constructor that accepts an integer parameter, whose value is used to initialize the sum instance variable. A method named getSum that returns the value of sum. A method named add that accepts an integer parameter. The value of sum is increased by the value of the parameter.

The following are the code in the C++ Programming Language.

//define header file

#include <iostream>

// using namespace

using namespace std;

//define a class

class Accumulator

{

//set private access modifier

private:  

//declare integer type variable

int sum;

//set public access modifier

public:

//define constructor  

Accumulator (int sum)

{

//refer the same class as instance variable

this->sum = sum;

}

//define integer type function

int getSum()

{

//return the value of sum

return sum;

}

//define void type function

void add (int value)

{

//variable sum is increased by the argument value

sum += value;

}

};
