I need help with this program it isnt working in microsoft visual studio. the code is below:

#include

#include

using namespace std;

//Prototypes for your functions: Input, Output, and Process will go here

void Input(string &cell_number, int &relays, int &call_length);

void Output(const string cell_number, const int relays, const int call_length, const double &net_cost, const double &call_tax, const double &total_cost_of_call);

void Process(const int relays, const int call_length, double &net_cost, double &call_tax, double &total_cost_of_call);

//Function Implementations will go here

///*************************************************************************************

//Name: Input

//Precondition: State what is true before the function is called.

// Example: the varialbes (formal parameters) have not been initialized

//Postcondition: State what is true after the function has executed.

// Example: the varaibles (formal parameters) have been initialized

//Description:

// Example:Get input (values of cell_number, relays, and call_length) from the user.

//PURPOSE: SHOW ME THAT YOU KNOW HOW TO READ INPUT AND USE INPUT (CALL BY REFERENCE) & OUTPUT (CALL BY VALUE) PARAMETERS

//FORMAL PARAMETERS ARE: cell_number (string), relays (integer), call_length (integer)

//*************************************************************************************

void Input(string &cell_number, int &relays, int &call_length) // example of all formal parameter using the call by reference mechanism in C++

{

cout << "Enter your Cell Phone Number: ";

cin >> cell_number;

cout << "Enter the number of relay stations: ";

cin >> relays;

cout << "Enter the length of the call in minutes: ";

cin >> call_length;

}

///*************************************************************************************

//Name: Output

//Precondition: State what is true before the function is called.

//Postcondition: State what is true after the function has executed.

//Description: Describe what the function does (purpose).

//*************************************************************************************

//NOTE: ALL FORMAL PARAMETERS ARE BEING PASSED BY VALUE. ALSO WE USED CONST TO MAKE SURE THEY WOULD NOT BE CHANGED BY MISTAKE

// USED THE SAMPLE OUTPUT TO HELP YOU FORMAT YOU OUTPUT

void Output(const string cell_number, const int relays, const int call_length, const double &net_cost, const double &call_tax, const double &total_cost_of_call)

{

//Use thee following statement to help you format you our output. These statements are called the magic formula.

cout.setf(ios::showpoint);

cout.precision(2);
