How do you solve fatal error in c program?

Answer 1

Fatal errors are errors or exceptions that cause a program to abort. You solve fatal errors by examining the source code to determine what is causing the error. If the error is an exception, it can be caught. That is precisely why we always place a catch-all exception handler in the main function. Once we know where the exception was raised we can write code to specifically deal with that exception -- at or near the point it was actually raised.

However, not all fatal errors throw exceptions. For example, a divide by zero operation is a fatal error because your program has allowed the system to attempt an illegal operation for which there is no reasonable means of recovery. The only solution is to avoid invoking illegal operations; test your assumptions and always assert that all operands are within the acceptable range of the operator.

Fatal errors can also be caused by hardware failure, such as bad RAM, which is beyond the remit of applications programmers.
