What is the need of base condition in recursion?

In a recursive function, the solution to the base case is provided and the solution of the bigger problem is expressed in terms of smaller problems. The role of the base condition is to stop a recursive function from executing endlessly – once a pre-specified base condition is met, the function knows it’s time to exit.

Is absence of base condition can cause infinite loop in recursion?

Explanation: If a recursive method does not have a base case which is necessary to meet the end of condition then an infinite loop occurs which results in stackoverflow exception error.

What happens if base condition is not defined in recursion 1 point executes the program runtime error compile time error infinite loop?

Explanation: Recursion is the process of defining something in terms of itself. Explanation: If a recursive method does not have a base case then an infinite loop occurs which results in Stack Overflow.

Which type of error will happen if there will be no exit condition for the recursion function?

Explanation: When a recursive function is called in the absence of an exit condition, it results in an infinite loop due to which the stack keeps getting filled(stack overflow). This results in a run time error.

What does base recursive case and tail recursion mean?

Base case: A case in recursion, in which the answer is known when the termination for a recursive condition is to unwind back. Tail Recursion: It is a situation where a single recursive call is consisted by a function, and it is the final statement to be executed. It can be replaced by iteration.

What is a recursive function without a base case called?

By definition, a recursive function without a base case keeps calling itself recursively forever and never returns. I wonder if you are confusing yourself with the term base case. Maybe it would be easier if you called it a termination condition. It’s simply the condition where the function does not make a recursive call.

What is the difference between recursion and iteration in C++?

Explanation: In recursion, the function calls itself till the base condition is reached whereas iteration means repetition of process for example in for-loops. 12. What happens if the base condition isn’t defined in recursive programs? Explanation: The program will run until the system gets out of memory.

What happens if you call a function without a base case?

As you can see, without a base case (at least without one that I just defined), you would infinitely be calling your own function. If you don’t set a base case, none of the calls will return.

What happens if the initial value of a recursive function is undefined?

Since the whole point of recursion is to have the base condition defined and then extend it by recursion, it would make no sense to call a recursive function with an “undefined” (whatever that means) initial value. Enjoy productive Java with IntelliJ IDEA.
