Question

Write a pseudo-code to calculate the factorial of a given number

Answer 1

1. Question⇒ Write a pseudo-code to calculate the factorial of a given number?

Step-by-step explanation:

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

Answer 2

The required solution to calculate the factorial of a given number is given below:

• Step 1: Declaring a number N and for a factorial fact and both are integer variables.
• Step 2: Initialize the variable fact to 1.
• Step 3: A value is taken for N from the user.
• Step 4: A condition is checked if N>0 and if the condition is not true then fact= 1.

• Step 5: If the above condition is true, then fact=fact*N.
• Step 6: The value of N is decreased by 1.
• Step 7: Step 4 and Step 5 are repeated until the value N becomes 0.
• Step 8: The value of the fact is printed.

The factorial of the given number N is stored in fact.
