Why does printing `wchar_t` values to the console result in hexadecimal addresses instead of characters?

Printing wchar_t Values to Console

When attempting to print wchar_t values using std::cout, users may encounter instances where only hexadecimal addresses appear in place of the intended characters. This anomaly occurs due to the mismatch between wchar_t, which represents wide characters, and std::cout, which is designed to handle narrow characters.

To rectify this issue, the problem answer suggests leveraging std::wcout instead.

SOLUTION

The code snippet below demonstrates the use of std::wcout to correctly print wchar_t strings:

#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;
}

By utilizing std::wcout, the wide characters in the wchar_t array are correctly interpreted and printed to the console, resolving the issue of hexadecimal addresses. This approach allows for the proper display of characters outside of the standard narrow character range, such as those encountered in different languages.
