This article demonstrates a Hello World program in C++.

Example

/* Include the standard I/O library. */
#include <iostream>  

/* Main function of C++ programs. */
int main(void)
{
    /* Print out some text to stdandard output. */
    std::cout << "Hello World" << std::endl;
                            
    /* Return a program status. */
    return 0;
}

Compilation

Here is a pseudo command to compile and run C++ code:

$ g++ -Wall -Wextra -o program source.cpp
$ ./program
Hello World
