<<Tutorial>> : Very Basic File I/O

[Trad]

Im not a file i/o wiz (yet) but i know a fair deal about it and i will try and explain the simple concepts. ok, nearly all the time you will need this header file

#include <fstream.h>

thats for In and Out. you declare what you want in the main function

ofstream = to read and write
ifstream = In stream, reading
ostream = Out strem, writing, so say i want to write "Hello world" to a file

#include <fstream.h>

int main() {
ofstream file("C:\\Folder\\File");
if (file.is_open()) {
file << "Hello World" << endl;
}
file.close();
return 0;
}

say we want to read from a file.

#include <fstream.h>
#include <iostream.h>

int main() {
ifstream readfile("C:\\Folder\\File");
char buffer[256];
if (readfile.is_open()) {
while (!readfile.eof()) {
readfile.getline(buffer,256);
cout << buffer << endl;
}
}
return 0;
}


thats a very simple, way, there is a LOT more about File I/O that i left out, like opening file modes etc.

If you request more, i will write in more detail.
