Recursive call is that this method call oneself.
Specially, Function uses this method.
Below C Source is example for recursive call function.
As you see, Function RF called the RF that is name of oneself.
Now I give you one question.
Please make Fibonacci sequence function using recursive call method.
You can see Fibonacci condition <here>
The LINUX that is name of OS is also recursive call type.
Some people said " LINUX is abbreviation of LINUX is not UNIX. "
Here, LINUX is call LINUX is not UNIX. In this sentence, LINUX is call LINUX is not UNIX again..
so..like that
(((((LINUX is not UNIX) is not UNIX) is not UNIX) is not UNIX) is not UNIX) is not UNIX
This case sink into the infinity roof because there is not escape condition. so we have to be careful when we use recursive call.
<English is very difficult.. Plz someone correct my poor sentence.>
