Standard input way?

I'm making a program to be opened this way:

Quote:

---

$ proj1 <in.file> out.file

---

How can i read the in.file using the stdin parameter?
How can i get the out.file name to create that output file?

Thanks!

You don't need to do anything at all.

fgets( buff, sizeof buff, stdin );
will read a line from the file.

printf( "hello world\n" );
would write to the output file.

Redirections are handled by the shell, not your program.

Are you serious? Each printf stays automatically saved in the output file without me making a fopen() to it? That's great.


But to read the inputfile using getc(stdin) how can i do it?

Thanks!

just do it...

So? As I said - just use it. No difference from the fgets approach Salem suggested... Instead of reading lines - read char by char

Code:

---

int c;
while((c=getc(stdin)) != EOF)
{
  process char here
}

ok thanks!! ;)
