C++ enforces stricter typing rules (no implicit violations of the static type system [1]), and initialization requirements (compile-time enforcement that in-scope variables do not have initialization subverted) [7] than C, and so some valid C code is invalid in C++. A rationale for these is provided in Annex C.1 of the ISO C++ standard.
The void type, in several programming languages derived from C and Algol68, is the return type of a function that returns normally, but does not provide a result value to its caller. Usually such functions are called for their side effects , such as performing some task or writing to their output parameters.
In the C and C++ programming languages, an inline function is one qualified with the keyword inline; this serves two purposes: . It serves as a compiler directive that suggests (but does not require) that the compiler substitute the body of the function inline by performing inline expansion, i.e. by inserting the function code at the address of each function call, thereby saving the overhead ...
static is a reserved word in many programming languages to modify a declaration. The effect of the keyword varies depending on the details of the specific programming language, most commonly used to modify the lifetime (as a static variable) and visibility (depending on linkage), or to specify a class member instead of an instance member in classes.
static void Main (string [] args) // string[] args can be omitted if the program doesn't have any command-line arguments. The main method is also allowed to return an integer value if specified. static int Main ( string [] args ) { return 0 ; }
In C and C++, volatile is a type qualifier, like const, and is a part of a type (e.g. the type of a variable or field). The behavior of the volatile keyword in C and C++ is sometimes given in terms of suppressing optimizations of an optimizing compiler: 1- don't remove existing volatile reads and writes, 2- don't add new volatile reads and writes, and 3- don't reorder volatile reads and writes.
Writing static void Main (string [] args) is equivalent to writing private static void Main (string [] args). The static keyword makes the method accessible without an instance of Program. Each console application's Main entry point must be declared static otherwise the program would require an instance of Program, but any instance would ...
public static String objectToString (Object myObject) {// This will only work when the myObject currently holding value is string. return (String) myObject;} public static void main (String [] args) {// This will work since we passed in String, so myObject has value of String.
