WebAutomation using C++

I have to open an Url which is this -> "https://ift.tt/3ysPPZk". Then after opening it. I have to select an Option called Authorize in it and enter my credentials to log in to it.

I have to do all these things in a single c++ program code.

I know there are better options available with other programming languages. So, anyone here suggests to me the possible ways to built c++ dll.

But here I would like to create a c++ dll which will be used in java in later times.

Thanks in advance. Waiting for exciting replies.

Yours Sincerely, Mustaq Ahmed Althaf Hussain
