wchar_t VS string

[chiwing]

what's the different between wchar_t and string?

thanks

[Null]

wchar_t is a data type and string is class to manipulate characters

[chiwing]

can char have more than one character ?

[Null]

No. For example,
char c='z';
is correct but
char c="asdf"; is imposible to compile. Only

char *g="asdf";
char b[]="asdf; 

are valid choices. But g or b just point to those characters.

No as char is one character but you can create an array
eg:
char array[] = "Hello!";

EDIT: Submitted too late

char *g="asdf";

why does it legal/ what is the value of g, after char *g="asdf";

[Bazzy]

It makes g pointing to a constant array generated by the compiler.
The value of g would be the location of the character 'a' of that array.

What about
char c = '1234';

Bwah hah ha hah haaah!

_{BTW. Don't use multi-character constants. They're evil.}
