New Lines

As it is mentioned before the object cout doesn’t give us the opportunity to start the message from a new line. So what should we do if we want to print the message or data to separate lines?

To insert a new line you can use endl manipulator:


              12345678
            
#include <iostream> 
using namespace std;
 
int main() {
    cout << "I love programming!" << endl;
    cout << "I love C++" << " and " << "Python!";
    return 0;
}

As a more compact alternative to endl you can also use \n character:


              12345678
            
#include <iostream>
using namespace std;
 
int main() {
    cout << "I love programming! \n" << endl;
    cout << "I love C++";
    return 0;
}

To create a blank line just use twice character \n after each other.

If you want to insert double quote characters to your message you can also use here the backslash \".

Завдання

Print two messages: "Hello!" and "I love C++!" separating them by a blank line:

Print the message "Hello!" with twice character \n.
Print the message "I love C++!".

Don’t forget about semicolon ; at the end of both these statements.
