Stack overflow is a condition that occurs when a program attempts to use more memory than is available on the stack. This can happen when a program has too many nested function calls, or when it uses recursion to solve a problem. Stack overflow can also occur when a program uses too many local variables, or when it allocates too much memory on the stack for a single variable.
There are many ways to avoid stack overflow. One way is to use tail recursion instead of regular recursion. Tail recursion is a technique that allows a program to call itself without using any additional stack space. Another way to avoid stack overflow is to use a stack guard. A stack guard is a special type of memory that is placed at the end of the stack. If the program attempts to use more memory than is available on the stack, the stack guard will be triggered and the program will be terminated.
