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;
}
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;
}
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;
}
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;
}
Note: Both
\nandendlare used to break lines. However,\nis most used. But what is\nexactly? The newline character (\n) is called an escape 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.Escape sequences always starts with a backslash. Escape sequences are important when you want to output special characters. For example, if you insert a double quote (") wrongly in your code, the program will fail. However, you can add a backslash in front of it, and then the output will be as expected.
Examples of other valid escape sequences are: Escape Sequence Description Try it \t Creates a horizontal tab \ Inserts a backslash character () " Inserts a double quote character
