C++ Syntax Let's break up the following code to understand it better: Example #include <iostream> using namespace std; int main() { cout << "Hello World!" ; return 0 ; } Try it Yourself » Example explained Line 1: #include <iostream> is a header file library that lets us work with input and output objects, such as cout (used in line 5). Header files add functionality to C++ programs. Line 2: using namespace std means that we can use names for objects and variables from the standard library. Don't worry if you don't understand how #include <iostream> and using namespace std works. Just think of it as something that (almost) always appears in your program. Line 3: A blank line. C++ ignores white space. But we use it to make the code more readable. Line 4: Another thing that always appear in a C++ program, is int main() . Th...
What is C++? C++ is a cross-platform language that can be used to create high-performance applications. C++ was developed by Bjarne Stroustrup, as an extension to the C language. C++ gives programmers a high level of control over system resources and memory. The language was updated 4 major times in 2011, 2014, 2017, and 2020 to C++11, C++14, C++17, C++20. Why Use C++ C++ is one of the world's most popular programming languages. C++ can be found in today's operating systems, Graphical User Interfaces, and embedded systems. C++ is an object-oriented programming language which gives a clear structure to programs and allows code to be reused, lowering development costs. C++ is portable and can be used to develop applications that can be adapted to multiple platforms. C++ is fun and easy to learn! As C++ is close to C, C# and JAVA, it makes it easy for programmers to switch to C++ or vice versa. Difference between C and C++ C++ was developed as an extension of ...
