c pointers stack overflow

What are pointers in C stack overflow?
In computer science, a pointer is a programming language data type whose value refers directly to (or "points to") another value stored elsewhere in the computer memory using its address._{30 sept. 2008}
There are several methods for detecting stack overflow in C / C++ programs:
There are several methods for detecting stack overflow in C / C++ programs:
1One of the most reliable ways is to use a memory debugging tool, such as Valgrind.
2) Valgrind can detect a range of memory issues, including stack overflows, and it can also provide detailed information about the source of the problem.

How to avoid stack overflow in C?

1Use a debugger: Debuggers allow you to inspect the program's execution and examine the call stack.
2) Enable compiler warnings: Modern compilers often provide warnings or hints about potential stack overflow issues.
3) Code review and testing: Review your code for recursive functions, large local variables, and deep nesting.

What happens when stack overflow in C?

When a stack overflow occurs, the excess data can corrupt other variables and address data, effectively changing variable values and overwriting return addresses.
In some cases, this will cause the program to crash.
