How do I call char constructor instead of char[] constructor

My school project asks me to re-create the std::string class (with less detail). I'm having a small problem that I have two conflicting(?) constructors.

The problem is when I want to create a String from a single character. Instead of calling

String(char);

it calls

String(char[]);

How can I specify which constructor I would like called?

Update Wow, now I feel silly. I was calling using char* and not a char so of course it would call the array/pointer version. Thanks for making this painfully obvious to me :)

Supposed you have the following

class String {
public:
    String(char);
    String(char[]);
};

you'll use 

char charvar = 'X';
String s(charvar);

to call the 1st form, and 

char strvar[] = "XXXX";
String s(strvar);

to call the second.

Beyond this your question is too unclear/unspecific, to give a concise answer for what you actually want to achieve.

You need to use single quotes to specify a char otherwise it will consider it a char[] with a single character (aside from the termination character)

'a'    // char
"a"    // char[]
