Re: [Dev-C++] what is wrong with the code

Dear Dawood,

> 	can anybody let me know, why the code below is not running.

That's probabely occuring as there is no conversion from char to
std::string. And thus, nor is there an assignment operator. You
are using the assignment operator in the following line:

>    string p = ch;

There is, however, a conversion from char* to std::string, and
you may want to suit from it like this:

string p = &ch;

But I do not recommend it. It would be nicer to explain your 
concrete problem more, so that we can help you more!

Regards,
--Hossein

I have not studied std::string/std::basic_string thoroughly yet but I
checked TC++PL a bit.

// Constructor
string s=3D'a'; is not valid.


However,=20

string s;

s=3D'a';=20

IS valid.


Also string::assign can be used in the way Haeri told me in a private =
email.


Also s.push_back('a'); can be used.

That is guaranteed to be undefined behaviour since there is no terminating
'\0' character.
