### Factorial of a number

Factorial of a number is represented by the symbol “!” and for any real positive number “n” it is written as “n!” where n! = 1 * 2 * 3 * …. * n. Here we will learn program for finding factorial of a number using C.

### Logic to find factorial of a number in c programming

Algorithm for finding factorial of a number with detailed explanation were discussed below:
1. Input a number and store it in a variable say "num".
2. Initialize another variable that will store factorial say "fact".
3. Run loop from 1 to num.
4. Multiply the current loop counter value.

### Program to find factorial of a number

#include<stdio.h>
int find_factorial(int);
main()
{
int num, fact;
//Ask user for the input and store it in num
printf("\nEnter any integer number:");
scanf("%d",&num);

//Calling our user defined function
fact =find_factorial(num);
//Displaying factorial of input number
printf("\nfactorial of %d is: %d",num, fact);
return 0;
}
find_factorial(n)
{
//Factorial of 0 is 1
if(n==0)
return(1);
//Function calling itself: recursion
return(n*find_factorial(n-1));
}


### Example

INPUT
Enter any integer number: 5
OUTPUT
Factorial of 5 is : 120
