**Chart/Diagram Description:**
The image primarily displays lines of C code and comments in a text editor interface.
There is a large gray circular icon with a white play arrow symbol in the bottom right portion of the image, overlayed on the code. This appears to be a UI element, likely for playing a video or simulation, and is not part of the code content or the programming problem description itself.
The code lines are numbered from 1 to 12 on the left side.
The requirement/question is stated in a multi-line comment block starting on line 1 and ending on line 3.
Line 5 includes the standard input/output library.
Lines 7 to 12 show the basic structure of the `main` function.
