    cout << "Enter any character: ";
    cin >> ch;

 	if(ch >= 'a' && ch <= 'z')
    {
        cout << ch<< " is lowercase alphabet.: ";
    }
    else if(ch >= 'A' && ch <= 'Z')
    {
        cout << ch<< " is uppercase alphabet.: ";
    }
    else
    {        
        cout << ch<< " is not an alphabet.: ";
