What error is typically encountered in a recursive function when there is no exit condition defined?

The error typically encountered in a recursive function when there is no exit condition defined is known as a "Stack Overflow" error.

Here's a step-by-step explanation:

1. A recursive function is a function that calls itself during its execution. This enables the function to be repeated several times, as it can call itself during its execution.

2. An exit condition (also known as the base case) is crucial in a recursive function to prevent it from running indefinitely. The exit condition is a condition under which a recursive function stops calling itself and begins returning values.

3. If no exit condition is defined, the function will keep calling itself indefinitely. This leads to an ever-growing stack of function calls.

4. The stack is a part of computer memory where each function call is added to the top of the stack along with its local variables. When a function finishes executing, its local variables and data are discarded and it's removed from the stack.

5. If the stack of function calls grows too large because the function keeps calling itself and never stops, it can exceed the stack size limit. This is known as a stack overflow.

6. A stack overflow error is a common error in many programming languages, and it typically results in the program crashing. This is the error you'll encounter in a recursive function when there is no exit condition defined.
