Question

In math a factorial is the number created by multiplying all the numbers from 1 up to and including the number. A factorial is a number followed by an exclamation mark (!). Examples: 3!=1∗2∗3 so 3!=6

5!=1∗2∗3∗4∗5 so 5!=120
​
Write the code to: - Tell your user that you are going to calculate the factorial. - Ask your user for the number - (You'll need to initialize 2 variables) - Loop until you've reached the number - factorial = factorial * current number - Print the factorial. HINT: don't try to calculate the factorial of a number larger than 10…... the numbers get big REALLY quickly.

Answer 1

To calculate the factorial of a number, you can use the provided code which involves taking user input and using a loop to multiply the numbers from 1 to the input value. The result is then printed as the factorial.

Step-by-step explanation:

To write the code for calculating the factorial, you can follow these steps:

1. Print a message notifying the user that you will calculate the factorial.
2. Ask the user for the number and initialize two variables, 'factorial' and 'current_number'.
3. Use a loop to iterate from 1 to the input number.
4. Within each iteration, update the variable 'factorial' by multiplying it with the 'current_number'.
5. Print the final value of 'factorial' as the result.

Remember to be cautious with larger numbers as the factorial grows rapidly.
