## Dart multiply strings:

In this post, we will learn how to *multiply* a string for *n* number of times. We can use the multiplication operator *** for that. Using this operator, we can *concatenate* the same string for *n* number of times.

In this post, we will learn how to use it with an example.

### Syntax of * operator:

*** operator is defined as below:

`String operator * (int times)`

If we multiply the string for *n* times, i.e. *str * n*, it will produce the string *n times* concatenating with itself. It is like *str + str +…n times*

If we provide the *n* value as zero or *negative*, it will return an *empty string*.

### Example of * operator:

Let’s take a look at the below example:

```
void main() {
var given_str = "hello";
print(given_str * 4);
print(given_str * 0);
print(given_str * -1);
}
```

If you run this program, it will print the below output:

```
hellohellohellohello
```

You can see that,

- The first print statement concatenate the same string
*4*times. - The second print statement returns
*empty*string - The third print statement returns
*empty*string
