Introduction to C++ Hello World! [edit] The first program that most aspiring programmers write is the classic "Hello World" program.
The purpose of this program is to display the text "Hello World! " to the user. The "Hello World" example is somewhat famous as it is often the first program presented when introducing a programming language[1]. #include <iostream> using namespace std; int main(){ cout << "Hello World! " The 'return 0;' as shown above, is not a necessary addition to the 'hello world' program. Understanding the Code[edit] Before discussing the particulars, it is useful to think of a computer program simultaneously in terms of both its structure and its meaning. A C++ program is structured in a specific, particular manner. The overall program has a structure, but it is also important to understand the purpose of part of that structure.
A line-by-line analysis of the program should give a better idea of both the structure and meaning of the classic "Hello World" program. #include[edit] int main()[edit] .
