//Hi,

//Ok to open a file in C/C++ do the following

FILE openFile(char *filename)
{
FILE fp;
if((fp = fopen(filename, "r+")) != NULL)
return fp;
else
return NULL;
}

/* the above function will open a specified file for reading + writing if successful. To write to the file you can simply use
*/

fprintf(fp, "My name is: %s", myName);

// and to read

fscanf(fp, "%s", input);

/* All the above functions apart from my own are defined in <stdio.h>, I know that is an ANSI C & not C++ function library, but it doesn't matter it will work anyway.

To delete a file is simple, all you have to do is call the remove() method defined in <stdio.h> and pass it the path to the file. NOTE: you probably already know this but just remember that the '\' character is an escape character and you will need "\\" to represent a '\' in C,C++ & Java.

Hope that helps

FILE address must be held in FILE pointers, and also the memory has to be new'd (in c++) in order that it doesn't get returned to the OS when the function ends. I was going to do a longer reply but I sneezed and hit the clear fields button by mistake so I cut it short, sorry if it appears *****y, it's not meant to.

very useful
1 thing i forgot is to ask how you shut down the puter..!
