R Program to find the factorial of a number1 min read

In this program, You will learn how to find the factorial of a number in R.

Example: How to find the factorial of a number in R

The output of this program would depend on the value of x that is entered by the user. Here is an example of what the output might look like:

In this example, the user entered 5 as the number, and the program calculates the factorial of 5, which is 120. The factorial of a number is the product of all the positive integers from 1 up to that number. For example, the factorial of 5 is 1 * 2 * 3 * 4 * 5 = 120.

The program first reads the number from the user using the readline() function and stores it in the variable x. It then initializes the variable f to 1, which is the starting value for the factorial.

The for loop iterates over the sequence of numbers from 1 to x, and on each iteration, the value of i is updated to the current number in the sequence. The variable f is updated to be the current value of f multiplied by the current value of i.

After the loop completes, the final value of f is printed to the console using the print() function. In this case, the final value of f is 120, which is the factorial of 5.
