C programmer: Simple data analysis. Sequential access files. Search for an integer

In this program, I will show you how to read data from sequential access files and simple ways to process them. At the very beginning, I decided to write a function that generates a file with random floating-point numbers, then implemented a function that finds the sum between these numbers and finds integers among them all.

Mistakes in the video: I called 0 a number that is not included in the sequence of integers, but it is included in this sequence. When creating the video, I confused integers with natural numbers (1, 2, 3, 4, ..., N).
