Write the implementation (.cpp file) of the  Accumulator class of the previous exercise. The full specification of the class is

LANGUAGE: C++

CHALLENGE:

Write the implementation (.cpp file) of the  Accumulator class of the previous exercise. The full specification of the class is:
An data member named  sum of type integer.

A constructor that accepts no parameters. The constructor initializes the data member sum to 0.
A function named getSum that accepts no parameters and returns an integer. getSum returns the value of sum .
A function named add that accepts an integer parameter and returns no value. add increases the value of sum by the value of the parameter.

SOLUTION:

Accumulator::Accumulator()
{
    sum=0;
}

int Accumulator::getSum()
{
    return sum;
}

void Accumulator::add(int theNum)
{
    sum+=theNum;
}
