Prompt

Create a 16:9 2D cartoon scene inside a computer museum. In the center of the exhibit hall, a programmer is demonstrating C language programming while many visitors gather around and watch. The screen should show clearly readable C code. Beside the programmer, place a sign that reads: "Ancient-Style Programming, Live Demo." Keep the composition playful, clean, and museum-like, with the programmer as the focal point.
