User inputted filename

[frankchester]

Hi, I have a string which stores the name of the file the user has inputted, but I have no clue how to input this into the opening of that file!

I thought that fp=fopen("%s", filename, "r"); would work, but it obviosuly is incorrect as I get an error.

How can I get the string stored in filename into the filename area of the opening code?

You should look at the prototype of fopen first

FILE * fopen ( const char * filename, const char * mode );

the first paramters is then const char *, which mean it can take any char pointer. In your if your read the file name in to variable like

scanf("%s", filename);

The file will be your char * pointer. Send that as your first argument to fopon literally. Like

fopen(filename,"r");

PS: And ofcourse do all the error checking.
