Simple file io. First hit on google - http://www.cprogramming.com/tutorial/cfileio.html. All you need to do is point the file pointer to your desktop. You can hard code that if you want. Then open the file for reading (see link), and print its contents to screen.

Do you want to print the contents to your screen or to the file? The way you opened the file there was for writing, that's what the w stands for. I was under the impression that you wanted to read the file. Use r for that. Look into fgets, or fscanf (if memory serves). http://www.cplusplus.com/reference/c...dio/fgets.html

It would be far more useful if you experimented with the code tags as opposed to the colour tags.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
Do not PM me for help; You'll be ignored, or told to learn to read.
Do not ask me if I'm muslim - I'm not. Nor do I care about yours or anyone else's mysticism. Religion is a matrix, take the RED PILL.

Yes, read the link you were given twice. It tells you how to do what you want. If not, ask a specific question.

my question is should I give the full path name as C :\\Documents and Settings\\Administrator\\Desktop\\myfile.txt in the as fopen("C:\\Documents and Settings\\Administrator\\Desktop\\myfile.txt", "r") function or should I give only fopen ("myfile.txt" , "r") in order to open a file from desktop and display its content on screen.
