Below programs illustrate the above function:
Program 1 :

// C++ program to illustrate
// putwchar() function

#include <bits/stdc++.h>
using namespace std;

int main()
{
    setlocale(LC_ALL, "en_US.UTF-8");

    // initiate the starting and
    // the last alphabet
    wchar_t first = L'\u05d0', last = L'\u05ea';

    wcout << L"All Hebrew Alphabets : ";

    // print all the alphabets
    for (wchar_t i = first; i <= last; i++) {
        putwchar(i);
        putwchar(' ');
    }

    return 0;
}

Output:

All Hebrew Alphabets : א ×? ×? ×? ×? ×? ×? ×? ×? ×? ×? ×? ×? ם ×? ×? ×  ס ×¢ ×£ פ ×¥ צ ק ר ש ת

Program 2 :

// C++ program to illustrate the
// putwchar() function

#include <bits/stdc++.h>
using namespace std;

int main()
{
    wchar_t wc;

    // initializing the first
    // and last alphabets
    wchar_t first = 'A', last = 'Z';

    wcout << L"All English Alphabets : ";

    // print all the alphabets from
    // first to the last
    for (wc = first; wc <= last; ++wc) {
        putwchar(wc);
        putwchar(' ');
    }

    return 0;
}

Output:

All English Alphabets : A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
