Does it matter where I place the asterisk when declaring pointers in C++?

Question

I\'m just learning C++ and from all the example code I have looked at over the past few days I am having a hard time understanding where the pointer should be placed.

There's no difference. They're exactly the same.

You can choose to write it however you like. Typically, C++ programmers place the asterisk next to the type, while it is more common for C programmers to place the asterisk next to the name of the variable.

The only pitfall to be aware of is when you declare multiple variables on a single line (which you really shouldn't do anyway, if not for precisely this reason). For example, in the following statement, only variable x is declared as a pointer:

char* x, y;

Compare that with the following, which makes it much more clear which variables are pointers:

char *x, y;

As best I can tell, the third syntax emerged as a poor compromise between the two leading options. Instead of placing the asterisk next to one or the other, someone decided to place it in the middle, which is about the only place it decidedly does not belong.
