C++New Lines
New Lines
To insert a new line in your output, 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;
}
Try it Yourself »using namespace std;
int main() {
cout << "Hello World!\n";
cout << "I am learning C++";
return 0;
}
You can also use another<< operator and place the\n character after the text, like this:
Example
#include <iostream>
using namespace std;
int main() {
cout << "Hello World!"<< "\n";
cout << "I am learning C++";
return 0;
}
Try it Yourself »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:
Example
#include <iostream>
using namespace std;
int main() {
cout << "Hello World!" << "\n\n";
cout << "I am learning C++";
return 0;
}
Try it Yourself »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 theendl manipulator:
Example
#include <iostream>
using namespace std;
int main() {
cout << "Hello World!" <<endl;
cout << "I am learning C++";
return 0;
}
Try it Yourself »using namespace std;
int main() {
cout << "Hello World!" <<endl;
cout << "I am learning C++";
return 0;
}
Both\n andendl are used to break lines. However,\n is most used.
But what is\n exactly?
The newline character (\n) is called anescape sequence, and it forces the cursor to change its position to the beginning of the next line on the screen. This results in a new line.
Examples of other valid escape sequences are:
| Escape Sequence | Description | Try it |
|---|---|---|
| \t | Creates a horizontal tab | Try it |
| \\ | Inserts a backslash character (\) | Try it |
| \" | Inserts a double quote character | Try it |
