Question

The standard C header file defines the function exit(). What does this tell us about the C++ header file ?

A) True
B) False

Answer 1

In C++, the function exit() is available when including the header file cstdlib, which serves a similar purpose as stdlib.h in C for terminating program execution.

Step-by-step explanation:

The question refers to the function exit() which is defined in the standard C header file stdlib.h. This function is used to terminate a program's execution. When a C++ program includes the header file cstdlib, it also makes available the exit() function. However, the question seems to contain a placeholder or a typo with which should likely be cstdlib. So the purpose of this function is to end the program and return control to the host environment. In C++, it's recommended to use C++-style headers, but cstdlib effectively serves the same purpose for the exit() function as stdlib.h does in C.
