file i/o

[erabyss]

I am writing a "labyrinth" style game. Minus the maze, because lack of graphic abilties. I used an array to mark the dimensions of the room. and with every step, I force the player to solve a problem.

I wrote the program below to write the "list" function for me. All that is left is to add the questions and answers. I need a program that can read from "file_A", which has a list from all my Q&A, and write to "file_B".

I know how to read from a file. But not how to copy specific lines of text. Do you know where I can find to code that will allow me to do that?

Thank you for your help. I cant wait to have this game finished.

#include <fstream>
#include <iostream>

using namespace std;

int main()
{
  int x;
  int y;
  
  ofstream a_file ( "list.cpp", ios::app );

  a_file<<"void list() \n{\n\nstring word2;\n\n";
  
  for ( x = 0; x < 4;x++ ) {
    for ( y = 0; y < 4; y++ )
 

  a_file<< "    if ((x == " << x << ") && (y ==" << y << "))\n    {"
    << "\n        string word2 = question(,,,); \n    }\n\n";
 
  }
a_file.close();

}

It will depend on the layout of the file.

Thats fine. I can set the file up any way I need to. If you can just point me towards a guide/tutorial that can show me how to write a program to do what I need. Or show me a code that I can look at and learn from. That would be awesome.

The way I have my program set up is: The functions that handles the questions returns 3 values.
1- The type of question it is.
2- The question the player needs to solve.
3- The answer to the question.

The guides I have been using only teach the basics of reading and writing to a file. What I use in the program above is as far as it goes. I can write to a file, append to a file, copy over a file, or print the texts of a file. I have no more control than that atm. I have looked but I havent found anything only that a noob like me can understand. I need to see a program to know how to use the code.

Thank you for all your help.

In that case, the getline (I think) function is probably going to be your key. Have each piece of info on its own line, and read the data in line by line.

=] Thank you WingedPanther, I will go look that up now. I'll post my results, so you know if it worked ot not. Thanks again.
