A pointer is a variable that represents the location of a data item, such as a variable or an array element. Pointers are used frequently in C, as they have a number of useful applications. For example, pointers can be used to pass information back and forth between a function and its reference point. Pointers provide a way to return multiple data items from a function via function arguments to
be specified as arguments to a given function.
Object- Oriented Programming (OOP) is an approach to program organization and development that attempts to eliminate some of the pitfalls of conventional programming methods by in incorporating the best of structured programming features with several powerful new concepts.
C++ classes group data with the functions that operate on it. Learn constructors, access specifiers, RAII and more — every example compiled and tested.
A constructor is a special method that is created when the object is created or defined. This particular method holds the same name as that of the object and it initializes the instance of the object whenever that object is created. The constructor also usually holds the initialization of the different declared member variables of its object.
As opposed to a constructor, a destructor is called when a program has finished using an instance of an object.
In C Programming, an array can be defined as number of memory locations, each of which can store the same data type and which can be referenced through the same variable name. Arrays can be of two types i.e. One Dimensional Array (such as lists) and Multidimensional Arrays (such as tables or matrices).
Functions are the building blocks of every C program. This complete guide covers declaration, call by value vs reference, recursion, and function pointers — with tested examples.
The standard way of handling all input and output is done with streams in C programming regardless of where input is coming from or where output is going to. This approach has definite advantages for the programmer. A library package has been evolved which is known as known as the Standard I/O Library which is used in any C program by using stdio.h header. First, however, we need to understand exactly what the terms input and output mean in context of C.
C programs are executed in a sequence, but we can control the execution of program by using any control mechanism by which we can compare things and come to a decision. This involves using some operations called Relational Operators, conditional statements called if-else and loops. We have fundamental operators to compare two values.
