What are the consequences of stack overflow?

If the call stack overflows, it means that the program has used more stack memory than allocated by the operating system for the current thread. This usually occurs due to infinite or excessively deep recursion, or because of allocating too much data on the stack.

Consequences:

• The program will crash with a StackOverflowException (in C#).
• Data loss and improper termination may occur.

Example:

void RecursiveMethod() {
    RecursiveMethod(); // infinite call
}

// When calling RecursiveMethod(), the stack will quickly overflow and the program will crash with a StackOverflowException.

To prevent stack overflow, you should control the recursion depth or use iterative algorithms.
