Benoit, wanna help me a bit? Maybe we can both learn from it.

Benoit · Oct 14th, 2004, 10:09 PM

I dunno...I'm still a beginner in C

jubbincake · Oct 14th, 2004, 10:24 PM

Lol, ok we can learn together then, do you know file IO and generating randome numbers and stuff like that.. this can be as easy or as hard as we want it. So we can start with an easy outline, then like update with new things we learn and stuff like that.

Benoit · Oct 14th, 2004, 10:28 PM

I haven't learned file I/O yet...I was playing around with Random numbers today. Do you have msn or AIM?

jubbincake · Oct 14th, 2004, 10:30 PM

Yea, my msn is bishfrontsixgunswitchblade@hotmail.com, add me so we can discuss this further if you want.

Here is a basic way to read a file:

(Toggle Plain Text)

#include<stdio.h>
 
int main() {
 
 FILE *fptr;
 char buffer[255];
 
 fptr = fopen("datafile","r");
  
 while ( (fgets(buffer,255, fptr)) != NULL)
  printf("%s", buffer);
 
 fclose(fptr);
 
 return 0;
}

(Toggle Plain Text)

Here is a data file named datafile
with a couple lines
of text inside it.

Lol, thats a bit confusing man.. but im gonna get that one book you suggested, the 3rd edition one, so it wont be long before i understand it.

I also wrote a few text-based games as the choose-your-own-adventure type... eventually turned them into MUDs... but now they cease to exist. It was rather fun though.

This a bit easier method, pulled from my file i/o library I wrote for college a long time ago:

(Toggle Plain Text)

void GetFileContent (string strFile)
{
   ifstream theFile(strFile.c_str());
   string line;
   while(!theFile.eof())
   {
     std::getline(theFile,line,'\n');
     cout << line << endl;
   }
}

C++ Primer 3rd edition will not show you how to use code like that, because the C++ commitee emphasises the standard library. The above code is how a C programmer might open a file and read text. A good book on C is called "Pointers on C" by Kenneth A. Reek, and "The C Programming Language" by D Ritchie.

but, I can do that stuff with C++ right, with the standard library?
