Answer this iin C++:Given main(), complete the Calculator class (in files Calculator.h and Calculator.cpp) that emulates basic functions of a calculator: add, subtract, multiple, divide, and clear. The class has one private data member called value for the calculator's current value. Implement the following constructor and public member functions as listed below:Calculator() - default constructor to set the data member to 0.0void Add(double val) - add the parameter to the data membervoid Subtract(double val) - subtract the parameter from the data membervoid Multiply(double val) - multiply the data member by the parametervoid Divide(double val) - divide the data member by the parametervoid Clear( ) - set the data member to 0.0double GetValue( ) - return the data memberGiven two double input values num1 and num2, the program outputs the following values:The initial value of the data member, valueThe value after adding num1The value after multiplying by 3The value after subtracting num2The value after dividing by 2The value after calling the clear() methodEx: If the input is:10.05.0the output is:0.010.030.025.012.50.0 main.cpp#include <iostream>#include <iomanip>#include "Calculator.h"using namespace std; int main() { Calculator calc;double num1;double num2; cin >> num1;cin >> num2; cout << fixed << setprecision(1);// 1.

Answer this iin C++:

Given main(), complete the Calculator class (in files Calculator.h and Calculator.cpp) that emulates basic functions of a calculator: add, subtract, multiple, divide, and clear. The class has one private data member called value for the calculator's current value. Implement the following constructor and public member functions as listed below:

Calculator() - default constructor to set the data member to 0.0
void Add(double val) - add the parameter to the data member
void Subtract(double val) - subtract the parameter from the data member
void Multiply(double val) - multiply the data member by the parameter
void Divide(double val) - divide the data member by the parameter
void Clear( ) - set the data member to 0.0
double GetValue( ) - return the data member

Given two double input values num1 and num2, the program outputs the following values:

The initial value of the data member, value
The value after adding num1
The value after multiplying by 3
The value after subtracting num2
The value after dividing by 2
The value after calling the clear() method

Ex: If the input is:

10.0

5.0

the output is:

0.0

10.0

30.0

25.0

12.5

0.0
