# C program to find factorial of a number using Ternary operator with Recursion1 min read

Recursion refers to the function calling itself directly or in a cycle.

Before we begin, you should have the knowledge of following in C Programming:

This C program calculates the factorial of a given number using recursion and the ternary operator. Here’s a brief explanation:

1. Function Definition: `factorial(int n)`
• This function calculates the factorial of a number `n`.
• It uses a ternary operator (`? :`) to check if `n` is 1 or 0. If true, it returns 1; otherwise, it recursively calls itself with the argument `n - 1` multiplied by `n`.
2. Main Function: `main()`
• The main function begins the execution of the program.
• It declares two variables: `num` for user input and `result` to store the factorial.
• The user is prompted to enter a number, which is then stored in the variable `num`.
• The `factorial` function is called with `num` as an argument, and the result is stored in the `result` variable.
• The program prints the factorial result.
3. Usage of `getch()`:
• The `getch()` function is used to hold the console window open until a key is pressed. Note that this function is not standard and may not be available on all systems.
4. Output:
• The program outputs the calculated factorial for the given input.
5. Termination:
• The program returns 0, indicating successful execution.
