int main( ) {  
   char ary[] = "Welcome to C++ tutorial at BASICLEARNER.COM";  
   cout << "Value of ary is: " << ary << endl;  
} 

Standard input stream (cin) example

#include <iostream>  
using namespace std;  
int main( ) {  
  int age;  
   cout << "Enter AGE: ";  
   cin >> age;  
   cout << "age is: " << age << endl;  
}  

Standard end line (endl) example

#include <iostream>  
using namespace std;  
int main( ) {  
cout << "C++ Tutorial";     
cout << " BASICLEARRNER"<<endl;   
cout << "End of line"<<endl;
