Hello World!

Adapted from: “Object-Oriented Programming Using C++” by Ira Pohl (Addison- Wesley)

Program to Display Hello World!

// Hello world in C++
#include <iostream>
#include <string>

using namespace std;

inline void pr_message(string s = "Hello World!")
{
    cout << s << endl;
}

int main()
{
    pr_message();
}

The above program is compiled and run using Gnu Compiler Collection (g++):

import os
root_dir = os.getcwd()

code_dir = root_dir + "/" + "Cpp_Code/Hello"

os.chdir(code_dir)

build_command = os.system("g++ hello.cpp -w -o hello")

exec_status = os.system("./hello")

Hello World!
