1. Basics

Omitting Namespace You can explicitly use the std:: prefix for standard library objects and functions instead of using the “using namespace std“. Example of Omitting Namespace Here’s a simple example to illustrate this − In this example we had directly used std::string and std::count instead of using using namespace std; When and Why to Omit Namespaces? Omitting namespaces in C++ can be […]

Printing “Hello, World!” is the first program in C++. Here, this prints “Hello, World” on the console (output screen). To start learning C++, it is the first step to print sometime on the screen. C++ Program to Print “Hello, World!” Let us see the first C++ program that prints “Hello, World!” − Open Compiler Output This program will print […]

While writing program in any language, you need to use various variables to store various information. Variables are nothing but reserved memory locations to store values. This means that when you create a variable you reserve some space in memory. You may like to store information of various data types like character, wide character, integer, floating point, […]

C++ Comments Program comments are explanatory statements that you can include in the C++ code. These comments help anyone reading the source code. All programming languages allow for some form of comments. Types of C++ Comments C++ supports two types of comments: single-line comments and multi-line comments. All characters available inside any comment are ignored by the C++ compiler. […]

When we consider a C++ program, it can be defined as a collection of objects that communicate via invoking each other’s methods. Let us now briefly look into what a class, object, methods, and instant variables mean. C++ Program Structure The basic structure of a C++ program consists of the following parts: To learn more […]

Local Environment Setup If you are still willing to set up your environment for C++, you need to have the following two softwares on your computer. Text Editor This will be used to type your program. Examples of few editors include Windows Notepad, OS Edit command, Brief, Epsilon, EMACS, and vim or vi. Name and […]

C++ is a statically typed, compiled, general-purpose, case-sensitive, free-form programming language that supports procedural, object-oriented, and generic programming. C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features. C++ was developed by Bjarne Stroustrup starting in 1979 at Bell Labs in Murray Hill, New Jersey, as an enhancement […]
