Concetti Chiave
- The program calculates and prints a specified number of n-polygonal numbers, which are related to polygons.
- The user is prompted to enter a polygonal side number greater than 2, ensuring valid input for calculations.
- The program uses a loop to repeatedly ask for a valid polygonal side number, displaying a message for invalid entries.
- The `polynum` function computes the n-polygonal number using a mathematical formula based on the side number and sequence position.
- The main function handles user input and manages the flow of the program to display the sequence of polygonal numbers.

Domande da interrogazione
- What is the purpose of the program described in the text?
- How does the program ensure the user inputs a valid polygonal side number?
- What is the function of the `polynum` function in the program?
The program is designed to print a specified number of n-poligonal numbers, which are a type of figurate number related to polygons.
The program prompts the user to enter a polygonal number greater than 2 and continues to request input until a valid number is provided, displaying an "Invalid value!" message for incorrect entries.
The `polynum` function calculates and returns the n-poligonal number based on the given side number `n` and the sequence position `h`, using the formula provided in the code.
