Segmentation fault error in c/c++ program, what steps to identify the root cause?

Question

Aryan Kumar · Answer

A segmentation fault error is a type of error that occurs when a program tries to access memory that it is not allowed to access. This can happen for a variety of reasons, including:
Trying to access an array element that is out of bounds.Trying to write to a read-only memory location.Trying to free memory that has not been allocated.
If you are getting a segmentation fault error in a C/C++ program, there are a few steps you can take to identify the root cause:
Check the code for errors. Make sure that there are no errors in the code that could cause a segmentation fault. For example, make sure that the array bounds are checked and that memory is not freed that has not been allocated.Use a debugger. A debugger can help you to track down the source of a segmentation fault error. The debugger will allow you to step through the code line by line and to see the value of the registers and the stack trace.Use a memory profiler. A memory profiler can help you to track the memory usage of your program. This can help you to identify the areas of your program that are using the most memory and to fix the problems that are causing the memory usage to be high.
Here are some additional tips for identifying segmentation fault errors:
Use a consistent naming convention for your variables. This will help you to identify segmentation fault errors more easily.Use comments to document your code. This will help you to understand what your code is doing and to identify potential problems.Use a unit testing framework. A unit testing framework can help you to test your code and to identify potential errors.
