How do you write a pseudocode for a factorial?

How do you write a pseudocode for a factorial?

Step-by-step explanation:

  1. Pseudocode for Factorial of a number :
  2. Step 1: Declare N and F as integer variable.
  3. Step 2: Initialize F=1.
  4. Step 2: Enter the value of N.
  5. Step 3: Check whether N>0, if not then F=1.
  6. Step 4: If yes then, F=F*N.
  7. Step 5: Decrease the value of N by 1 .
  8. Step 6: Repeat step 4 and 5 until N=0.

What is factorial algorithm?

Algorithm of this program is very easy − START Step 1 → Take integer variable A Step 2 → Assign value to the variable Step 3 → From value A upto 1 multiply each digit and store Step 4 → the final stored value is factorial of A STOP.

What is recursive factorial?

A recursive function is a nonleaf function that calls itself. The factorial function can be rewritten recursively as factorial(n) = n × factorial(n – 1). The factorial of 1 is simply 1. Code Example 6.27 shows the factorial function written as a recursive function.

How do you use pseudo code?

Rules of writing pseudocode

  1. Always capitalize the initial word (often one of the main 6 constructs).
  2. Have only one statement per line.
  3. Indent to show hierarchy, improve readability, and show nested constructs.
  4. Always end multiline sections using any of the END keywords (ENDIF, ENDWHILE, etc.).

What is pseudo code computer?

Definition: Pseudocode is an informal way of programming description that does not require any strict programming language syntax or underlying technology considerations. It is used for creating an outline or a rough draft of a program.

What is factorial used in real life?

Another use for the factorial function is to count how many ways you can choose things from a collection of things. For example, suppose you are going on a trip and you want to choose which T-shirts to take. Let’s say that you own n T-shirts but you have room to pack only k of them.

What is a factorial of hundred?

(pronounced “one hundred factorial”) is the number you get when you multiply all the whole numbers from 1 to 100. That is, 100!
