## Cobol Program for Factorial of a Number

## What is algorithm write for factorial Program?

We first take input from user and store that value in variable named “n”. Then we initialize a variable “Fact” with value 1 (i.e Fact=1) and variable i with value 1(i.e i=1). Repeat next two steps until i is less than n. At last, print the value of Fact.

What is the algorithm for factorial?

Hence, n! is denoted as a Factorial of n. A factorial is denoted by “!”. So, suppose, you want to find the factorial of the number n, then **n!** **= n * (n-1) * (n-2) * (n-3)** …

What is pseudo code write for factorial program?

Step-by-step explanation:

**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.

How do you write a factorial algorithm in Java?

**Let’s see the factorial program in java using recursion.**

- class FactorialExample2{
- static int factorial(int n){
- if (n == 0)
- return 1;
- else.
- return(n * factorial(n-1));
- }
- public static void main(String args[]){

## How do you find the factorial of a number in Cobol?

PROCEDURE DIVISION. move 16 to n move 0 to i move 1 to fact perform until i greater than n move i to ist move fact to factst display ist “! = ” factst add 1 to i multiply i by fact on size error display “value too big” end-multiply end-perform. stop run.

How do you find the factorial of a number in programming?

**Factorial Program using loop**

- #include<stdio.h>
- int main()
- {
- int i,fact=1,number;
- printf(“Enter a number: “);
- scanf(“%d”,&number);
- for(i=1;i<=number;i++){
- fact=fact*i;

What is factorial programming?

Factorial of a positive integer (number) is **the sum of multiplication of all the integers smaller than that positive integer**. For example, factorial of 5 is 5 * 4 * 3 * 2 * 1 which equals to 120. Factorial Program in C: All positive descending integers are added together to determine the factor of n.

How do you find the factorial of a number in CPP?

…

Example: Find the Factorial of a Given Number.

i <= 4 | fact *= i |
---|---|

1 <= 4 | fact = 1 * 1 = 1 |

2 <= 4 | fact = 1 * 2 = 2 |

3 <= 4 | fact = 2 * 3 = 6 |

4 <= 4 | fact = 6 * 4 = 24 |

What is factorial C++ program?

Factorial Program in C++: **Factorial of n is the product of all positive descending integers**. Factorial of n is denoted by n!. For example: 4!

## How do you find factorial in assembly language?

**Algorithm –**

- Input the Number whose factorial is to be find and Store that Number in CX Register (Condition for LOOP Instruction)
- Insert 0001 in AX(Condition for MUL Instruction) and 0000 in DX.
- Multiply CX with AX until CX become Zero(0) using LOOP Instruction.
- Copy the content of AX to memory location 0600.

How do you calculate factorial in programming?

Algorithm of Factorial Program in C

Ask the user to enter an integer to find the factorial. Read the integer and assign it to a variable. From the value of the integer up to 1, multiply each digit and update the final value. The final value at the end of all the multiplication till 1 is the factorial.

How do you find the factorial in pseudocode?

- SET factorial := 1, i := 1.
- WHILE i <= number DO.
- COMPUTE factorial := factorial * i.
- INCREASE i by 1.
- END LOOP.
- PRINT factorial.

## How do you code a factorial?

**Let’s see the factorial Program using loop in java.**

- class FactorialExample{
- public static void main(String args[]){
- int i,fact=1;
- int number=5;//It is the number to calculate factorial.
- for(i=1;i<=number;i++){
- fact=fact*i;
- }
- System.out.println(“Factorial of “+number+” is: “+fact);

How do you code Factorials?

**Let’s see the factorial Program using loop in java.**

- int number=5;//It is the number to calculate factorial.
- for(i=1;i<=number;i++){
- fact=fact*i;
- }
- System.out.println(“Factorial of “+number+” is: “+fact);

How do you code Factorials in C++?

…

Example: Find the Factorial of a Given Number.

i <= 4 | fact *= i |
---|---|

2 <= 4 | fact = 1 * 2 = 2 |

3 <= 4 | fact = 2 * 3 = 6 |

4 <= 4 | fact = 6 * 4 = 24 |

5 <= 4 | Loop terminates. |

How do you write a factorial in Python?

**Using built-in function**

- # Python program to find.
- # factorial of given number.
- import math.
- def fact(n):
- return(math.factorial(n))
- num = int(input(“Enter the number:”))
- f = fact(num)
- print(“Factorial of”, num, “is”, f)
