Error while defining char array

[Boogie El Aceitoso]

Hi,

I have this code:

std::string::va lue_type * wh[] = {'\t'};

But it gives a compiler error, comlaining that it can't convert int to char.

What am I doing wrong?

Bad diagnostic since the error is not in converting an int to a char
but in converting a char into a valuetype *. Should it just be a
valuetype?

Declaring an array of pointers-to-value-type. Try:

std::string::va lue_type wh[] = {'\t'};

Rewrite as:
std::string::va lue_type * wh[] = {"\t"};
or as:
std::string::va lue_type wh[] = {'\t'};

Right, but I don't understand why OP is using string::value_t ype
anyway, since by definition it's 'char'.

char wh = '\t';

Probably the OP also has wchar_t's and maybe some other,
and wants to make that connection clear.

Probably just trying to get his head around it.
