A file as input in C

Question

I need to input a file in a c program for Linux

a.out < inputfile

The problem is that i don't know how to receive a file

it can't be like:

FILE *fp;
char filename[100];
fopen = (fp,"r");
...

I need as input the file, no the name.

Is there anyway to do this?

You can read it by reading `stdin`. – wildplasser Dec 07 '15 at 00:36 — wildplasser, Dec 07 '15 at 00:36
@wildplasser Wouldn't just use argc, argv work better? – Rivasa Dec 07 '15 at 00:38 — Rivasa, Dec 07 '15 at 00:38

Use stdin as your file pointer. It's already declared and open You don't need an fopen
