So I have had an idea for a program to create a text / console output game. I wanted to make the game solely in the console output using cout but had a different idea.

I understand that a program can open a file, read the information, edit / manipulate the information and output that information into a different file. So something like this:

#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>

using namespace std;

void fileWrite(int Health);  // Prototype for fileWrite

int main()
{  
  string inFile = "inFile.txt";
  string outFile = "outFile.txt";
  int Health = 100;

  ifstream fin;
  ofstream fout;

  fin.open("inFile.txt");
  fout.open("outFile.txt);

  while (!fin.oef())
  {
   fin >> Health;
   fileWrite(Health);
  }

 fin.close();
 fout.close();
 return 0;
}

void fileWrite(int Health)
{ 
 fout << setw(10) << left << "Health" << endl;
 fout << setw(10) << left << Health << endl;
}

So let's say inFile.txt simply has 50 in the file. Like so:

50

In theory, the file should be read, health is now set to 50, the function fileWrite is called and the output should look like this in the outFile.txt 

Health:
50

So what I am wanting to do is make it so that say instead of reading in a file for the health, could I modify Health multiple times during the duration of the program and call fileWrite? Say that health pertains to the main character, and I create a variable named potion and it does +20 towards health, could I open the file. See that the character has 50 health, output the information into the outFile.txt then take potion which would increase the health to 70 and reprint the file?

The reason I am trying to find a way to do this is so that the user can use the console for inputting commands, and have the .txt file show the results of the commands.

Can a function be created to handle the printing and be called multiple times in main?
