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 data...

Suppose there is astructure in cthat contains function pointers, this function pointer stores the address of the function that calculates the salary of an employee (Grad1 and Grad2 officer). //structure contains function pointer typedef struct ...
Many programming languages support UDTs, including the following: C.C supports four UDTs. These are structure, enumeration (enum), union and typedef. Structures allow users to group items of different data types into a single type, while enum is useful to create custom data types with a set ...
A pointer is a very powerful and sophisticated feature provided in the C language. A variable defined in a program the compiler allocates a space in the memory to store its value. The number of bytes allocated to the variable depends on its type. For ins
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...
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 point? And there are these DWORDS and QWORDS for 32-bit and 64-bit integers. Why not use normal int...
What is C Language?C programming language was designed by the Dennis Ritchie in 1972 in Bell Labs. It was developed to rewrite the code of Unix operating system, later it was launched for other/general purposes. C language is a general purpose, structural programming language which follows the...
