[[File:BjarneStroustrup.jpg|right|thumb|Bjarne Stroustrup, the creator of C++]]
'''C++''' (pronounced "see plus plus") is a [[computer]] [[programming language]] based on [[C programming language|C]]. It was created for writing programs for many different purposes. In the 1990s, C++ became one of the most used programming languages in the world.
The C++ programming language was developed by [[Bjarne Stroustrup]] at [[Bell Labs]] in the 1980s, and was originally named "C with classes". The language was planned as an improvement on the [[C programming language]], adding features based on [[object-oriented programming]]. Step by step, a lot of advanced features were added to the language, like [[operator overloading]], [[exception handling]] and [[templates (programming)|templates]].

C++ is a general-purpose programing language which means that it can be used to create different variety of applications. [https://codinggrammar.com/what-is-cpp-used-for/ C++ is used for] variety of application domains.
== Example ==
The following text is C++ source code and it will write the words "[[Hello world program|Hello World!]]" on the screen when it has been [[compiled language|compiled]] and is executed. This program is typically the first program a programmer would write while learning about programming languages.
<syntaxhighlight lang="cpp">
// This is a comment. It's for *people* to read, not computers. It's usually used to describe the program.
// Make the I/O standard library available for use in the program.
#include <iostream>
using namespace std;
// We are now defining the main function; it is the function run when the program starts.
int main()
{
// Printing a message to the screen using the standard output stream std::cout.
cout << "Hello World!";
}
</syntaxhighlight>
This program is similar to the last, except it will add 3 + 2 and print the answer instead of "Hello World!".
<syntaxhighlight lang="cpp">
#include <iostream>
int main()
{
// Print a simple calculation.
std::cout << 3 + 2;
}
</syntaxhighlight>
This program subtracts, multiplies, divides and then prints the answer on the screen.
<syntaxhighlight lang="cpp">
#include <iostream>
int main()
{
// Create and initialize 3 variables, a, b, and c, to 5, 10, and 20.
int a = 5;
int b = 10;
int c = 20;
// Print calculations.
std::cout << a-b-c;
std::cout << a*b*c;
std::cout << a/b/c;
}
</syntaxhighlight>
