Difference between Basemap* basemap and Basemap *basemap

[mmgis]

Dear all,

Can some body explain the difference between

1. Basemap* basemap

and

2. Basemap *basemap

for 1, it is an object creation, But what defines that?



Thanks in advance

There is no difference. They both create an uninitialized variable basemap as a pointer to type Basemap. Whether you use 1) or 2) is really a matter of choice. I prefer 2). Consider

Basemap* basemap1, basemap2;

This creates variable basemap1 as a pointer to Basemap and variable basemap2 as type Basemap. The * doesn't bind with the type but with the variable so in this case only basemap1 is a pointer. Consider

Basemap *basemap1, *basemap2;

In this case both basemap1 and basemap2 are pointers to Basemap.
