Meaning and Function of a character..

I have been looking at some source code, and I have come across a certain character that I can't figure out what it does or what it means: %s

What is this? What does it do? What can it be replaced with?

Thank you, and I hope someone can help me..

That looks like part of a printf format string. Look up printf and sprintf in the manual.

Yeah, I figured it out today, by looking at the printf function and by testing it with echo and so on..

Thanks though, I really appreciate it!
