![]() | Section 2: A First Program |
Before diving right into the nitty-gritty of C++ language details, let's get started with a full-fledged C++ program! The idea of this program is to introduce you to the overall structure of a C++ program and give you the flavor of C++.
Here, then, is an entire C++ program:
//include this file for cout #include <iostream.h> int main() { //print out the text string, "Hello, World!" cout << "Hello, World!" << endl; return 0; }
To prepare for the next section, create a new text file and save this code into the file. If you are on a unix machine, save the file with the filename hello.C (make sure it ends with .C, not .c!). If you are on a Windows machine, save the file with the filename hello.cpp.
You're now ready to compile and run your program, covered on the next page.
