Concetti Chiave
- The program calculates and prints polygonal numbers for a given side.
- Users input the polygonal side, which must be greater than 2.
- The program prompts for the number of polygonal numbers to display.
- The core calculation is handled by the polynum function, which computes using the formula for polygonal numbers.
- Invalid input for the polygonal side (less than 3) prompts an error message.
