Recursion is a function that calls itself. It has an if statement to stop the recursive calls and prevent infinite loops. Recursion decreases code size but uses more processor time and space. It is difficult to debug due to tracing recursive calls. Any recursive function must have an if statement to terminate the calls or it will never return.

4. Recursion:
A function is called recursive when it calls itself
There is always if statement in recursive function .To force
the function to return without recursive call being
executed otherwise the function goes in infinite loop.

6. Advantages
.It Decreases the Size of Coding

7. .Recursion takes lot of space.
.Difficult to trace for debugging for programmers.
.It must have if statement to stop recursive call Otherwise Function Will never
return.
.Its Uses more Processor time.
Disadvantages of Recursion
