debug my c++ code in qtcreator

I am looking for someone to help me debug my C++ code in Qt Creator. Specifically, I need help correcting errors that are preventing my code from working correctly. There may be certain special cases I’m not considering that need to be taken into account, so my ideal freelancer will be able to think critically and deeply about the project in order to get the best results. After all errors have been corrected, the application should also be tested for functionality. If you think you are the right for this project, please get in touch!

need this done ASAP
