Factorial Computation
To compute factorial of a given number:
Input: Given the Number to be computed => N.
Output: Factorial of N is Fact.
Step 1: Input Number whose Factorial is to be computed: N.
Step 2: Initialize Fact =1.
Assign N = M.
Step 3: Check if M is greater than 1.
Yes: Assign product of Fact and M to Fact.
Decrement M. Repeat Step 3.
No: Output Factorial of N is Fact.
Step 4: Stop.
Qus. 1 : Which variable must be initialized to 1 in the algorithm for factorial computation?
- Counter
- Factorial value
- Input number
- Loop limit
