C++ Standard Template Library in Practice - Project - Custom Writer Function

The video tutorial covers the continuation of a project involving Bitcoin data handling. It begins with setting up a custom writer function for the curl library to capture data into a program. The tutorial explains the creation and attachment of a data handler function, integration of a JSON API, and modification of the fetch function to return a JSON object. The main program is implemented with error handling and JSON parsing, leading to a formatted output displaying Bitcoin values. The video concludes with a summary and encouragement to modify the project.
