Question

So I have, let’s say

float x;

and I have

 LPCWSTR message=L"X is";

how can I create a LPCWSTR with the message

“X is [x]”

?

Answer 1

You could use wstringstream:

#include <string>
#include <sstream>
#include <iostream>

int main()
{
    float x = 0.1f;
    std::wstringstream s;
    s << L"X is " << x;
    std::wstring ws = s.str();
    std::wcout << ws << "\n";

    return 0;
}

and create an LPCWSTR from it if required, or just use the std::wstring.
