How to Print wchar_t Values to the Console Correctly?

Printing wchar_t Values to the Console

When working with wchar_t values, which represent wide characters that encompass multiple bytes, printing them directly to the console using std::cout can result in hexadecimal values being displayed instead of the intended characters. To print wchar_t strings correctly, there are two recommended approaches.

1. Use std::wcout:

The std::wcout stream explicitly handles wide characters, allowing for correct printing of wchar_t values. To use this approach, replace std::cout with std::wcout in your code:

wcout << ru << endl << en;

This will print the "Привет" and "Hello" strings in their respective languages.

2. Explicitly Cast to char:

If you need to use std::cout, you can explicitly cast the wchar_t values to char before writing them to the console. This approach is less preferable but can be useful if std::wcout is unavailable:

cout << (char*)ru << endl << (char*)en;

However, note that this method may not work correctly for characters that cannot be represented using the default character encoding of your system.
