How to Print wchar_t Values and Strings to the Console in C ?

Printing wchar_t Values to the Console

In C , the wchar_t type is used to represent wide characters, which can hold a broader range of characters than the standard ASCII characters. When attempting to print wchar_t values to the console using the standard cout stream, the result may appear as hexadecimal values or addresses instead of the actual characters.

Printing wchar_t Strings

To correctly print wchar_t strings to the console, you need to use the specialized wide character output stream, std::wcout. This stream is designed to handle wide characters and will correctly render them as characters rather than hexadecimal values.

To illustrate the usage of std::wcout, let's consider the following code example:

#include <iostream>

using namespace std;

int main()
{
    wchar_t en[] = L"Hello";
    wchar_t ru[] = L"Привет"; //Russian language
    wcout << ru << endl << en;
    return 0;
}

In this code, the wcout stream is used to print both the Russian and English strings to the console. By using wcout, the characters are correctly displayed as:

Привет
Hello

Note: The ability to correctly print wchar_t characters depends on your system's locale settings. If the system cannot represent certain characters in your locale, they may still appear as hexadecimal values.
