1.In iteration and recursion in C++, what happens if a condition is never true or there is no exit point?

In both iteration and recursion, if a condition is never true or there is no exit point, it results in an infinite loop or infinite recursion respectively.

1. Iteration: In iteration, if the condition in the loop (for, while, do-while) is never true, the loop will continue to execute indefinitely. This is known as an infinite loop. It will consume CPU resources and can potentially cause the program to crash or become unresponsive.

2. Recursion: In recursion, if there is no exit point (base case), the function will keep calling itself indefinitely. This is known as infinite recursion. It will consume stack memory for each recursive call. When the stack memory is exhausted, it will result in a Stack Overflow error, causing the program to crash.

In both cases, it's important to ensure that there is a valid condition that will eventually be met to terminate the loop or recursive calls.
