C++ Output - Cout

The cout object, together with the << operator is used to output values/print text. You can add as many cout objects as you want.

#include <iostream>
using namespace std;

int main() {
  cout << "Hello World!";
  cout << "My C++ Program";
  return 0;
}

Output:

Hello World!My C++ Program

To insert a new line, you can use the \n character.

Note: Two \n characters after each other will create a blank line.

#include <iostream>
using namespace std;

int main() {
cout << "Hello World! \n\n";
cout << "My C++ Program";
return 0;
}

Output:

Hello World!

My C++ Program

This is another way to insert a new line. With the endl manipulator, you can use a newline.

#include <iostream>
using namespace std;

int main() {
cout << "Hello World!" << endl;
cout << "My C++ Program";
return 0;
}

Output:

Hello World!
My C++ Program

Both \n and endl are used to break lines. However, \n is used more often and is the preferred way.
