Question

I have to input a string into an unsigned short array.

Here is my implementation:

unsigned short strFile [ 200 ] = {0};
cin >> strFile;

I have included the iostream.h header.

But I always get an error:

error C2678: binary ‘>>’ : no operator found which takes a left-hand operand of type ‘std::istream’

Anybody knows how should I solve this?

Answer 1

There is no kind of string that would be compatible with unsigned short[].

There is normal string that is char [] (in C++ you should always keep it in string except for constants!) and wide string, that is wchar_t[] (in C++ you should always keep it in wstring). And C++11 adds char16_t and char32_t and their corresponding u16string and u32string.

You can read normal string from normal input stream like cin. You can read wide string from wide input stream like wcin.

wchar_t used to be typedef to unsigned short in C, but C++ requires it to be a separate type. ISO/IEC
14882:2003 3.9.1/5:

Type wchar_t is a distinct type whose values can represent distinct codes for all members of the largest extended character set specified among the supported locales (22.1.1).
