Array question (cpp)

Hi there,
Is it possible to use a char * as an index for an array? For example:
I used to do this with PHP, but c++ just isn't having this!

No. Regular arrays are only indexable with integral values. If you want to index by something else, use a map [std::map, or the new core::map].

Code: Select all
#define TEST_INDEX 0
#define BLAH_INDEX 1
#define somethingElse 2
#define Text 3
int numIndex[Text] = 43;
Its kinda lame, and probably not recommended, but it works.

Don't use defines, and even more important: Don't use lower case characters in defined strings. Guess what happens with your code if you later write 'char* Text = "x"'
