File reading with c/c++

[yrinfish]

I want to be able to do this on a file:

Code: Select All | Copy To Clipboard

1	myChar = getTheNthCharOrSomething(9);

that for example in pseudo-code, getTheNthCharOrSomething() is this:

Code: Select All | Copy To Clipboard

1 2 3

char getTheNthCharOrSomething(where) {     return file.charAt(where); }

file is a global var.

Hmmm, good question. You would open a file, copy its contents in a string, then run a substr on it.

[yrinfish]

and how to copy it in a string?

[Juju]

Use fgets.

But I need whatever comes after a newline too

Ah, nevermind, I found a more efficient way. Use fseek to seek to the nth character, then fgetc to get that character.
