Exit 0 In Dev C++
If status is EXITFAILURE, an unsuccessful termination status is returned to the host environment. Otherwise, the status returned depends on the system and library implementation. For a similar function that does not perform the cleanup described above, see quickexit. Parameters status Status code. If this is 0 or EXITSUCCESS, it indicates. Dalam bahasa C, terdapat 4 pernyataan yang dapat digunakan untuk melakukan peloncatan, yaitu break, continue, goto dan fungsi exit. Pada kesempatan kali ini kita akan membahas mengenai pernyataan peloncatan menggunakan Fungsi Exit dalam C lengkap dengan contoh program beserta penjelasannya, dimana contoh program kami buat menggunakan IDE Dev-C.
-->Controls conditional branching. Statements in the if-block are executed only if the if-expression evaluates to a non-zero value (or TRUE). If the value of expression is nonzero, statement1 and any other statements in the block are executed and the else-block, if present, is skipped. If the value of expression is zero, then the if-block is skipped and the else-block, if present, is executed. Expressions that evaluate to non-zero are
- TRUE
- a non-null pointer,
- any non-zero arithmetic value, or
- a class type that defines an unambiguous conversion to an arithmetic, boolean or pointer type. (For information about conversions, see Standard Conversions.)
Syntax
Example
if statement with an initializer
Visual Studio 2017 version 15.3 and later (available with /std:c++17): An if statement may also contain an expression that declares and initializes a named variable. Use this form of the if-statement when the variable is only needed within the scope of the if-block.
Example
In all forms of the if statement, expression, which can have any value except a structure, is evaluated, including all side effects. Control passes from the if statement to the next statement in the program unless one of the statements contains a break, continue, or goto.
The else clause of an if..else statement is associated with the closest previous if statement in the same scope that does not have a corresponding else statement.
if constexpr statements
Visual Studio 2017 version 15.3 and later (available with /std:c++17): In function templates, you can use an if constexpr statement to make compile-time branching decisions without having to resort to multiple function overloads. For example, you can write a single function that handles parameter unpacking (no zero-parameter overload is needed):

[[noreturn]]void exit(int exit_code ); | (since C++11) |
Causes normal program termination to occur. Precision tune auto care owings mills.
Several cleanup steps are performed:
1) destructors of objects with static storage duration are called in reverse order of completion of their constructors or the completion of their dynamic initialization, and the functions passed to std::atexit are called in reverse order they are registered (last one first). a) any static objects whose initialization was completed before the call to std::atexit for some function F will be destroyed after the call to F during program termination. b) any static objects whose construction began after the call to std::atexit for some function F will be destroyed before the call to F during program termination (this includes the case where std::atexit was called from the constructor of the static object) | (until C++11) |
1) The destructors of objects with thread local storage duration that are associated with the current thread, the destructors of objects with static storage duration, and the functions registered with std::atexit are executed concurrently, while maintaining the following guarantees: a) The last destructor for thread-local objects is sequenced-before the first destructor for a static object b) If the completion of the constructor or dynamic initialization for thread-local or static object A was sequenced-before thread-local or static object B, the completion of the destruction of B is sequenced-before the start of the destruction of A c) If the completion of the initialization of a static object A was sequenced-before the call to std::atexit for some function F, the call to F during termination is sequenced-before the start of the destruction of A d) If the call to std::atexit for some function F was sequenced-before the completion of initialization of a static object A, the start of the destruction of A is sequenced-before the call to F during termination. e) If a call to std::atexit for some function F1 was sequenced-before the call to std::atexit for some function F2, then the call to F2 during termination is sequenced-before the call to F1 | (since C++11) |
- In the above,
Exit 0 In Dev C 5
- if any function registered with
atexitor any destructor of static/thread-local object throws an exception, std::terminate is called - if the compiler opted to lift dynamic initialization of an object to the static initialization phase of non-local initialization, the sequencing of destruction honors its would-be dynamic initialization.
- If a function-local (block-scope) static object was destroyed and then that function is called from the destructor of another static object and the control flow passes through the definition of that object (or if it is used indirectly, via pointer or reference), the behavior is undefined.
- if a function-local (block-scope) static object was initialized during construction of a subobject of a class or array, it is only destroyed after all subobjects of that class or all elements of that array were destroyed.
Exit 0 In Dev C 4
exit_code is 0 or EXIT_SUCCESS, an implementation-defined status indicating successful termination is returned. If exit_code is EXIT_FAILURE, an implementation-defined status indicating unsuccessful termination is returned. In other cases implementation-defined status value is returned.Stack is not unwound: destructors of variables with automatic storage duration are not called.
[edit]Relationship with the main function
Returning from the main function, either by a return statement or by reaching the end of the function performs the normal function termination (calls the destructors of the variables with automatic storage durations) and then executes std::exit, passing the argument of the return statement (or 0 if implicit return was used) as exit_code.
