c++ syntax vs java – Iampsp Blog

C# Syntax

In the previous chapter, we created a C# file called Program.cs, and we used the following code to print “Hello World” to the screen:

Program.cs

using System;

namespace HelloWorld
{
  class Program
  {
    static void Main(string[] args)
    {
      Console.WriteLine("Hello World!");    
    }
  }
}

Result:

Hello World!

C++ Syntax

Let’s break up the following code to understand it better:

Example

#include <iostream>
using namespace std;

int main() {
  cout << "Hello World!";
  return 0;
}

Example explained

Line 1: #include <iostream> is a header file library that lets us work with input and output objects, such as cout (used in line 5). Header files add functionality to C++ programs.

Line 2: using namespace std means that we can use names for objects and variables from the standard library. Continue reading C++ Syntax
