C++ input integer print unicode

Question

I'm trying to output Unicode that corresponds to an integer value entered by the user. This is being done on windows 10 in C++ by the way. Currently I can print Unicode with this code:

_setmode(_fileno(stdout), _O_U16TEXT);

wprintf(L"\u0006");'''

My question is, how do I attach the variable to the Unicode?

Answer 1

Something like this

wchar_t wstr[2] = { variable, L'\0' };
wprintf(L"%ls", wstr);

Alternatively, you can avoid the expense of wprintf with

wchar_t wstr[2] = { variable, L'\0' };
fputws(wstr, stdout);

In both cases variable is the integer variable you mentioned. You might want to check that is in range for a wchar_t and you might want to add a cast to suppress any compiler warning.
