The correct syntax for accessing the length of an array named numbers is:

The syntax is truly dependent on the programming language, as different languages have different API's. 

But, the most standard form of accessing an array length is via a method or property by dot notation.

For example -

for(int i = 0; i <= m_Array.Length; i++) {...}

This code is from C#, using the Length property.

Is this a statement or question?
