Hello World Program
This is very simple program. You can write it easily. The exact code for this program is given below. #include <iostream> using namespace std; void main() { cout<<"Hello World!"<<endl; system ("pause"); } Explanation: In the first line , #include <iostream> it is c++ built in library. This library provides some functions that are very useful. You will understand it gradually, when you will study functions and classes in c++. As a beginner, it is enough for you to remember that it is a built in library and you have to include it in every code or program. The second line using namespace std; make it easy for you to use input stream cin>> , output streams cout<< , and other function like endl easily. If you do not use it or if you want to skip it then you will have to write std::cout<< instead of only cout<< , std::cin>> instead of cin>> and std::endl instead...
