How do I convert an 'unsigned char' to 'string'

Hi there, how do I convert a variable of type unsigned char to string. thanks

Do you want a string containing a single character?

unsigned char uc = /*...*/;
std::string s(1, static_cast<char>(uc));

thank for your reply. I want a string containing a max of 256 characters

containing a max of 256 characters

do I convert a variable of type unsigned char to string

How would you convert a single character to the several? Describe what you have and what are you want to achieve. Preferrably with examples.

OK, I have a variable of type unsigned char; this variable contains a once word string. So I want to convert this variable from the type unsigned char to std::string please see the example below.

unsigned char myVar[10] = "abcdefg"

I want to convert the variable above to type std::string.

You have array, not a single char.

#include <string>
#include <iostream>

int main()
{
    unsigned char myVar[10] = "abcdefg";
    std::string res(myVar, myVar + 7);
    std::cout << res;
}

that doesn't work either.

YOu just might do something wrong.

could it have anything to do with the fact that the variable i am trying to convert to string is actually of type uint8_t. I did not disclose this because as far as I know uint8_t is simply a typedef for unsigned char.
