Such as in the beginning of the program written like this:
Typedef int MazeType [5] [6].
MazeType m;
The first sentence is what mean? Not that typedef but some existing variable a new name, it is defined by an array of type int
Since the first sentence defines an array, so the second sentence?

CodePudding user response:

Declare MazeType is a two-dimensional array type alias
Define variables m

CodePudding user response:

Typedef int MazeType [5] [6].
MazeType m;

Equivalent to int m [5] [6]

Basically is to use substitution method, see a few times also become accustomed to,

Don't upset oh,, when you write programs kind enough, you will find that, at the time of writing some programs, see that a long list of type name is really a headache,,

For example:
List : : iterator m_itrListUser;
Every time to define an iterator for the container, it takes so long to write type name,,,

But if at the beginning of the program to change the name:
Typedef list : : iterator itrIntList;

So then I only need to write:
ItrIntList m_itrListUser;
Good,,

Beautiful Angle, no matter from the code or legibility, or typing efficiency, has promoted,,

CodePudding user response:

Typedef int MazeType [5] [6].
Can look like this:
Remove the typedef and MazeType, MazeType type is int [5] [6]
