Answer this in 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 main.cpp #include #include #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 in 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
