Dynamic initialization states that we are initializing the objects at the runtime. Since we use constructors to initialize everything, here we are going to use dynamic constructors. Here is an example of dynamic initialization: Output: This dynamic initialization can help us to create different constructors having the same function name but different parameters. If you …
We can pass objects as arguments in member or non member functions. They can be passed either by value or reference. Pass by value creates another copy of the particular object which is deleted after the function is ended. Pass by reference means that we are passing the same object as a reference so if …
In any programming language loops play an important role in building our logic and successfully implementing it. In this article, we are going to see nested for loop in C++. Nested for loop means a for loop inside another for loop. Let’s see the syntax first and after that, we will some examples. Syntax: Here …
‘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 …
