What is NULL pointer and how it is defined? For a user-defined data type, what should be used typedef or #define? Is char string[5] = "Hello"; valid? Missing ampersand/address of (&) in scanf() (C language Error) Too few arguments to function (C language Error) ...
Learn: What are self-referential classes in C++ programming language, why they are important for development purpose? What is self-referential class in C++?It is a special type of class. It is basically created for linked list and tree based implementation in C++. If a class contains the ...
Apointeris a very powerful and sophisticated feature provided in the C language. A variable defined in a program the compiler allocates a space in thememoryto store its value. The number of bytes allocated to the variable depends on itstype.For instance, acharacteris allocated 1 byte, aninti...
1. Mark the following statements as true or false: a. In C++, "pointer" is a reserved word. b. In C++, pointer variables are declared using the word "pointer". c. The statement "delete p;" deallocates Here are some type and variable declarations in C syntax: typedef...
When trying to code something using it, it feels like I am writing a completely different language. Like seriously, for example, they have a typedef of LPVOID, which literally means a normal void pointer. Something even more ridiculous is typedefing "void" as "VOID". What even is the ...
Note that the type of the size_t typedef is compiler-dependent; it is a typedef for unsigned int in Visual C++. A good solution is to use an enumerated type such as this: C++ Copy enum class my_type : size_t {}; Then, change your definition of placement new and delete to use...
Language expressiveness improvements like the ability to explicitly override or make "final" virtual functions Improvements to object construction, like initialization lists, delegating constructors and explicit control over auto-generated functions Template improvements including templated typedefs, variadic ...
String classes, like MFC/ATL's CString implement two versions using macro. There are two classes named CStringA for ANSI, CStringW for Unicode. When you use CString (which is amacro/typedef), it translates to either of two classes. Okay. The TCHAR type-definition was for a single characte...
into a single type, while enum is useful to create custom data types with a set of named integer constants. Typedef is used to rename existing data types, and the union data type can contain elements of different data types, with all members of the union stored in the same memory ...
