I'm working on an engine for running various simple text-based adventures based on nodes with a limited range of options for the player to select from. (a working beta with a partially complete example module is attached)

Currently, I'm trying to clean up the code so that I can rewrite the event and link parsers into something more effective, but ran into some problems with a function supposed to load the contents of a text file into an array of strings.

What works:
- The number of lines is correctly counted and stored in the counter the external function uses
- The array is created and the lines are loaded from the file into it
- The array contains the correct contents in the filetostrarray() function

What DOESN'T work:
- load_paragraph() doesn't have access to the strings in the array and crashes the program when trying to display them

In void load_paragraph():

string parfile=par_file(current_node);
int lines;
string *line;
filetostrarray(parfile, &lines, line);

In filetostrarray

void filetostrarray(string file, int* lines, string *readlines) {
 *lines=lines_in_file(file);
 if (*lines) { fstream line_in(file.c_str(), ios::in);
			  readlines=new string[*lines];
			  for &#40;int i=0; i<*lines; i++&#41; getline&#40;line_in, readlines&#91;i&#93;&#41;;
			  line_in.close&#40;&#41;;
			  line_in.clear&#40;&#41;; } }

Another half an hour of trial and error resulted in a solution.

EDIT: Wrong code.

I must be blind, but how do the 2 posts differ ?

[the_fifth_horseman]

They didn't, I posted the wrong code.  

In void load_paragraph():

string parfile=par_file(current_node);
int lines;
string *line;
filetostrarray(parfile, &lines, &line);

void filetostrarray(string file, int* lines, string **readlines) { 
*lines=lines_in_file(file);
 if (*lines) { fstream line_in(file.c_str(), ios::in);
			  *readlines=new string[*lines];
			  for &#40;int i=0; i<*lines; i++&#41;
						   { getline&#40;line_in, &#40;*readlines&#41;&#91;i&#93;&#41;;}
			  line_in.close&#40;&#41;;
			  line_in.clear&#40;&#41;; }
 }
