Please help me with this problem using c++.

Finish the following code: void Divide (int dividend, int divisor, bool& error, float& result) // Set error to indicate if divisor is zero. // If no error, set result to dividend / divisor. { using namespace std; // For debugging cout << "Function Divide entered." << endl; cout << "Dividend = " << dividend << endl; cout << "Divisor = " << divisor << endl; //** // Rest of code goes here. //** // For debugging if (error) cout << "Error = true "; else cout << "Error = false "; cout << "and Result = " << result << endl; cout << "Function Divide terminated." << endl; }

The main program containing the main function should be named main.cpp. The function definition file containing a function for the volume calculation and a function for the surface area calculation should be named SphereCalc.cpp. The function declaration file containing function declarations for the functions should be named SphereCalc.h. Make sure you include a Header Guard. Read the Radius from the Keyboard. If a negative number is provided, set the calculated value to zero.
