NettetA recursive function is called the tail-recursive if the function makes recursive calling itself, and that recursive call is the last statement executes by the function. After that, there is no function or statement is left to call the recursive function. Let's write a program to demonstrate the tail recursion in C programming language.

NettetThe C programming language supports recursion, i.e., a function to call itself. But while using recursion, programmers need to be careful to define an exit condition from the function, otherwise it will go into an infinite loop.

NettetLeft Recursion- A production of grammar is said to have left recursion if the leftmost variable of its RHS is same as variable of its LHS. A grammar containing a production having left recursion is called as Left Recursive Grammar. Example- S → Sa / ∈ ( Left Recursive Grammar) NettetRecursion is the process which comes into existence when a function calls a copy of itself to work on a smaller problem. Any function which calls itself is called recursive function, and such function calls are called recursive calls. Recursion involves several numbers of recursive calls.
