Expert C for an urgent small job($150)

Job ID: 31549624

Budget: $30 – $250 USD

I am looking for an expert in C.
This is the open-source I am using now. https://github.com/exploitagency/vanitygen-plus
When I input "vanitygen -X 0 -P 04c8dfa71886ae5f73a0727d6cb4a8018e7359778518cb6348cc14460d80b7594d585ac10d7dd4ab5c9fa699f9dad49238e091f1b008269ece707a1b54c9b6d83f 1abc",
they are showing "privkeypart".
Like that

Difficulty: 4553521
Pattern: 1abc

PrivkeyPart: 5JxTHonhFPfybJUtQXP1dse7m57fmLTzi4b6n4o7LzZu7Ve5WGn

But I need privkey in the output.
The code is already in the source code to output privkey.
So I need someone who can help to show the right privkey when I input.
