course of C++ programming language
lecture 1: making and using objects
The first program
In all its glory, the following code is the simplest C++ program you're likely to encounter.
// helloworld.cpp
#include
int main (int argc, char *argv[])
{
std::cout << "Hello, World!" << std::endl;
return 0;
}
This code, as you might expect, prints the message Hello, World! on the screen. It is a simple program and unlikely to win any awards, but it does exhibit several important concepts about the format of a C++ program.
