## 6.3 The Empty Statement

The empty statement does nothing:

The empty statement can be useful as a place holder. For example, if a `for` statement contains all of the necessary functionality in its header, the body of the `for` statement can be the empty statement. Here's an example:

    // Find the first element of array nx that equals 5
    int x;
    for (x = 0; x < nx.length && nx[x] != 5; x++)
    // for requires a statement here: use an empty statement
        ;
    if (x < nx.length) {
    // The for statement found a 5 at nx[x]
    }
