C++ Output (Print Text)
C++ Output (Print Text)
The cout object, together with the << operator, is used to output values/print text:
Example
#include <iostream>
using namespace std;
int main() {
cout << "Hello World!";
return 0;
}
using namespace std;
int main() {
cout << "Hello World!";
return 0;
}
You can add as many cout objects as you want. However, note that it does not insert a new line at the end of the output:
Example
#include <iostream>
using namespace std;
int main() {
cout << "Hello World!";
cout << "I am learning C++";
return 0;
}
using namespace std;
int main() {
cout << "Hello World!";
cout << "I am learning C++";
return 0;
}

C++ New Lines
To insert a new line, you can use the \n character:
Example
#include <iostream>
using namespace std;
int main() {
cout << "Hello World! \n";
cout << "I am learning C++";
return 0;
}
using namespace std;
int main() {
cout << "Hello World! \n";
cout << "I am learning C++";
return 0;
}
Tip: Two
\n characters after each other will create a blank line:
#include <iostream>
using namespace std;
int main() {
cout << "Hello World! \n\n";
cout << "I am learning C++";
return 0;
}
using namespace std;
int main() {
cout << "Hello World! \n\n";
cout << "I am learning C++";
return 0;
}
Another way to insert a new line, is with the
endl manipulator:Example
#include <iostream>
using namespace std;
int main() {
cout << "Hello World!" << endl;
cout << "I am learning C++";
return 0;
}
 
using namespace std;
int main() {
cout << "Hello World!" << endl;
cout << "I am learning C++";
return 0;
}
Both
\n and endl are used to break lines. However, \n is used more often and is the preferred way.
