    I didn't even need to read the post, your thread subject told me EVERYTHING I needed to know about your problem.

    Read the rules and post properly next time.

    How do i load a whole file in to an array?
    Look up the ReadFile() function.

    How do you want your array set up? You could have every element of the array be a character, a line, or a paragraph. You could even have something else depending on how your file is formatted. You need to be a helluva lot more specific. Posting code would be very helpful.

    i'm assuming your data file is set up the way i have mine for the battle system... in that case...
    Code:
    	ifstream infile("stats.dat");	//open stats file
    	while(infile.getline(filename,20,' '))	//while more usernames, take it in
    	{
    		if(!strcmpi(filename,username))	//if filename matches
    		{
    			if(debug)
    			{
    				cout<<username<<"::"<<filename<<endl;	//test string
    				system("pause");	//test pause
    			}
    			infile.ignore(100,'h');	//ignore password field
       			infile>>hp>>null>>atk>>null>>def>>null>>lvl>>null>>exp>>null
       				>>mon>>null>>points;
       			break;	//end loop
       		}
       		else
       			infile.ignore(1000,'\n');	//ignore rest of line
    	}
    	infile.close();	//close file
    just modify that to fit your needs

    Here is some code I've used before to read in a file into an array...maybe you'll find it usefull somehow:
    Code:
    void readFromInputFile( char *text,     // large array to store input text
                            long &index,    // number of input file characters
                            char fileName[])// filename to use for input
    {
       ifstream inStream;                  // Input file stream
       ofstream outStream;                 // Output file stream
    
       // Set value of index to start at 0, in case we're calling this function a second time
       index = 0;
    
       // open input file
       inStream.open(fileName);   // associate the actual file name with "inStream"
       if ( inStream.fail() ) {
          cout << "Input file opening for " << fileName << " failed.\n"
               << "The file either doesn't exist or is not in the current directory.\n"
               << "Exiting...\n\n" << endl;
          exit(-1);
       }
    
       /*
       // open output file for debugging purposes
       outStream.open("output.txt");   // associate the actual file name with "inStream"
       if ( outStream.fail() ) {
          cout << "Output file opening for output.txt failed.\n"
               << "The file either doesn't exist or is not in the current directory.\n"
               << "Exiting...\n\n" << endl;
          exit(-1);
       }
       */
    
       // Read in the characters into our big array
       while ( inStream.get(text[ index++]) ) {
          if ( index >= MaxSize) {
             cout << "MaxSize of " << MaxSize << " was reached.\n";
             break;
          }
          // outStream << text[ index-1];     // for debugging
       }
    
       // close the input file
       inStream.close();
    
    }

    some entropy with that sink? entropysink.com
