Would this be your iPad Passcode, or AppleID Password?
An iPad passcode cannot be reset or modified from another device. If your iPad is disabled, or the iPad passcode is not recognised, you have no alternative other than to follow this process:
If you’ve forgotten the passcode on your iPad, or your iPad is disabled – Apple Support
You’ll need access to either a PC (with iTunes installed) or a Mac (with iTunes or Finder - as appropriate for the installed version of MacOS).
Download and use iTunes for Windows – Apple Support
Update to the latest version of iTunes – Apple Support
Use of a PC or Mac is unavoidable. If you don’t have access to a suitable computer of your own, that of a helpful friend or family member will suffice. Alternatively, the technicians at the Genius Bar of your local Apple Store or Apple Authorised Service Provider (AASP) will be delighted to assist.
You may also need your AppleID and associated password. If these have also been forgotten, they can be recovered here:

To recover your credentials, you’ll need access to one of the following:
- Your primary email address mailbox that corresponds with your AppleID
- Any of the secondary/recovery email addresses that should be configured for your AppleID account
- Any of the trusted telephone numbers (fixed line or Cellular/Mobile) that are associated with your AppleID
Unless you AppleID account has not been fully/correctly configured, or has been seriously neglected, recovery of the AppleID and password should not be difficult.

When you recover access to your credentials, you would be well advised to log-in to your AppleID account from a web browser - and verify/update any email addresses and trusted telephone numbers:

As for connection of your iPad (with USB-C connection) to a computer with an older USB Type-A port, you clearly cannot use the USB-C to USB-C charging cable supplied with your iPad and Power Adapter. Instead you simply require a USB3 Type-A to USB-C cable - an MFI Certified cable being recommended. Whilst these cables should be available from good computer stores, Apple market appropriate cables in a variety of lengths. Here are two examples of MFI Certified cables manufactured by Mophie:
