C++ Developer - Sequential File Input

The video tutorial covers reading data from files, known as file input, using a simple text editor to create a text file. It demonstrates how to read integers from a file using C++ code, including handling end-of-file conditions. A challenge is presented to store and print the numbers read from the file using an appropriate data structure, with a solution provided using vectors. The tutorial emphasizes the importance of file IO for data persistence and retrieval.

What is the purpose of using an accumulator in the code?
