First Class In C++ Adapted from : http://www.cplusplus.com/doc/tutorial/tut1-1.html Structure of a C++ program Probably the best way to start learning a programming language is with a program. So here is our first program: // my first program in C++ #include <iostream.h> int main () { cout << "Hello World!"; return 0; } Hello World! The left side shows the source code for our first program, which we can name, for example, hiworld.cpp. The right side shows the result of the program once compiled and executed. The way to edit and compile a program depends on the compiler you are using. Depending on whether it has a Development Interface or not and on its version. Consult section compilers and the manual or help included with your compiler if you have doubts on how to compile a C++ console program. The previous program is the first program that most programming apprentices write, and its result is the printing on screen of the "Hello World!" sentence. It is one of the simpler programs that can be written in C++, but it already includes the basic components that every C++ program has. We are going to take a look at them one by one:
