The C exit() function is a standard library function used to terminate the calling process. When exit() is called, any open file descriptors belonging to the process are closed and any children of the process are inherited by process 1, init, and the process parent is sent a SIGCHLD signal. It is defined inside the header file.
The C abort() function is the standard library function that can be used to exit the C program. But unlike the exit() function, abort() may not close files that are open. It may also not delete temporary files and may not flush the stream buffer. Also, it does not call functions registered with atexit().
The C assert() function is a macro defined inside the header file. It is a function-like macro that is used for debugging. It takes an expression as a parameter, 1. If the expression evaluates to 1 (true), the program continue to execute. 2. If the expression evaluates to 0 (false), then the expression, source code filename, and line num...
