files

hi im trying to read from a file that has been created by the user.

my problem

file = fopen("data/hello.txt", "r");

is that. I want the user to enter the name of a file he/she wants to read rather than specifying it in the code...

how would i do that?
thanks

You can use a string as the file name.

Code:

char a[] = "data/hello.txt";
file = fopen(a, "r");

-Prelude

Or in your case you could request a filename from the user, placing it in a variable and then using the variable to open the file.

Code:

FILE *fd;
char file[256];
printf("What file would you like to open?\n ");
gets( file );
fd=fopen(file, "r");

Bad Fido. No cookie. Never use gets. Always assume your user will do everything in their power to break your user interface. Always. As such, never ever use gets.

Quzah.
