If we have a lot of conditions it’s quite difficult to combine all of them using only if and else statements. For this reason, in C++ you can use the `switch` statement to define as many cases as you want. Use the following syntax:

```
switch (expression) {
    case a:
        // code expression is equal to a
        break;
    case b:
        // code expression is equal to b
        break;
}
```

We are evaluating here **expression** using `switch` statement. If expression is equal to one of the possible `cases` (`a` or `b`), we execute code in the correspending block. The keyword `break` at the end of case blocks means that when code in this block is executed we go out of the switch block.

> You can use as many `cases` as you want.

int weekendDay = 1;
switch (weekendDay) {
&nbsp;&nbsp;&nbsp;&nbsp;case 1:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;cout << "It's Saturday";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;break;
&nbsp;&nbsp;&nbsp;&nbsp;case 2:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;cout << "It's Sunday";
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;break;
}

The code above prints the day of the weekend by its number. If it’s the first day (`1`) the code prints `"It's Saturday"`, if it’s the second day - `"It's Sunday"`.

> The keyword break is optional and we will describe it more later.
