Basic programming help

[godzsmilez]

Hello,
I am kinda of stuck and needing help... I have to write a small mini program for class and I so far got this code but its not working and running, I can't figure out what to do with the 'startProgram' part, one classmate said to do a cin and cout but i already put it, can anyone help me on what is wrong?


#include <iostream>
#include <string>
using namespace std;
string getInput(string);
void start(string);
void getName(string);
void getAge(int);
void getMileage(double);
//declare variables
//input as string
string userInput = "";
//name as string
string name = "";
//age as integer
int age = 0;
//mileage as double
double mileage = 0.0;
int main ()
{
//call DisplayApplicationInformation
cout << "This program accepts user input as a string, then makes the appropriate data conversion." << endl;
start(startProgram);
getName(name);
getAge(age);
getMileage(mileage);


return 0;
}//call DisplayDivider(“Start Program”)
void start(string startProgram)
{
cout << startProgram << endl;
}//call DisplayDivider(“Get Name”)
void getName(string name)
{
//set name = GetInput(“Your Name”)
userInput = getInput("Your Name: ");
//display “Your name is: “ + name
getline(cin, userInput);
cout << "Your name is: " << name << endl;

}
//call DisplayDivider(“Get Age”)
void getAge(int age)
{
//set input = GetInput(“Your Age”)
userInput = getInput("Your Age: ");
//set age = convert input to integer
age = atoi(userInput.c_str());
//display “Your age is: “ + age
cout << "Your Age is: " << age << endl;
}
//call DisplayDivider(“Get Mileage”)
void getMileage(double mileage)
{
//set input = GetInput(“Gas Mileage”)
userInput = getInput("Gas Mileage: ");
//set mileage = convert input to double
mileage = atof(userInput.c_str());
//display “Your car MPG is: “ + mileage
cout << "Your car MPG is: " << mileage << endl;
}

First of all, please edit your post in order to include the code inside code tags. See http://cplusplus.com/articles/z13hAqkS/ for an explanation on how this is done.

Second, please be specific: Saying "is not working" and not saying WHY or at least describe the desired behavior is not helpful. "It is not working because it is doing this and I need it to do that instead". Something along that line. Also include any error messages that you may be getting either during runtime or during compilation.
