‘this’ is a reserved keyword in c++. It is used to get the variables or member functions present in the current class. ‘this’ pointer is not available for the friend functions because they are not members of class. It is given as an implicit argument to the member functions. Let’s see the code below to …
Whenever we call a member function inside another member function of one class it is known as Nesting of the member function. Generally, the member function which is called by another member function is kept private so that it cannot be called directly using the dot operator. Let’s look at the example code below for …
A C++ Program includes a set of commands running to obtain the desired result. Every program in C++ is structured in an organized and specific way. It starts from importing header files at the start which is followed by the main function containing the code in its body. Structure of C++ Program Header Files Through …
Global variables are described at the top of a program, outside of all functions. The value of a global variable remains constant throughout the execution of the program. Every function that is declared in the program, can access the global variable. Output: If a global variable is not initialized, then the default value is zero. …
In this article, we look into the delay() function in C++. There can be many cases where we need to create a delay in our programs before exiting out of execution. We can use a delay for this purpose in our code which is used to delay the program’s exit time. We can call the delay …
Most new C++ programming students are taught to add “using namespace std” in the global scope after introducing the headers needed for their programs to compile successfully. As a result, students grow accustomed to engaging in this practice without realizing how bad it is. Including ‘using namespace std’ in the global scope is bad practice. …

In this section we will be studying the concepts of variables in C++ programming language. We hope you guys must have heard about variables in C or somewhere else. Though it is not a very complex topic to discuss in detail but let’s see what we have to say for this. C++ Variables We can …
Here you will learn about C++ tokens, keywords, constants, identifiers, strings, operators and special symbols. What are Tokens? In simple words, we can say that tokens are the smallest component pertaining to any program that make sense to the compiler, i.e. compiler can very easily understand that. We can classify the tokens into six different …
