How do you find the factorial of a number efficiently?

The following is a detailed algorithm for finding factorial. 1) Create an array ‘res[]’ of MAX size where MAX is number of maximum digits in output. 2) Initialize value stored in ‘res[]’ as 1 and initialize ‘res_size’ (size of ‘res[]’) as 1. 3) Do following for all numbers from x = 2 to n.

How do you find the factorial of a while loop in Python?

Using While Loop

1. num = int(input(“enter a number: “))
2. fac = 1.
3. i = 1.
4. while i <= num:
5. fac = fac * i.
6. i = i + 1.
7. print(“factorial of “, num, ” is “, fac)

How do you solve 8 Factorials?

= n × ( n − 1 ) ! This means that the factorial of any number is, the given number, multiplied by the factorial of the previous number. So, 8! =8×7!

What is the factorial of 10 in C program?

Below we have calculated factorial for numbers 1 to 10. Factorial of Ten (10!) = 10*9*8*7*6*5*4*3*2*1 = 3628800 Below is the common mathematical formula for determining the numbers ‘ n ‘ factor. n! = n ( n – 1) ( n – 2) ( n – 3) …… In this section, we are going to discuss how factorial is calculated in the C program using different methods.

How to find factorial of a number using printf in C?

The last printf statement will print the Factorial output of the user entered integer. Within the printf statement, the first \%d refers to Number, and the second \%d refers to Factorial. This program for the factorial program in c allows you to enter any integer value. By using the value, this C program find Factorial of a Number using While Loop

How to find factorial of a number using call by reference?

C Program to Find Factorial of a Number Using Call By Reference. This factorial program allows the user to enter any integer value. Instead of User entered value, the address of the variable will be passed to the Function we created. Within this User defined function, this c program find Factorial of a number using For Loop.

How to find factorial of a number using for loop in C?

/* C Program to Find Factorial of a Number Using For Loop */ #include int main () { int i, Number; long Factorial = 1; printf (“n Please Enter any number to Find Factorialn”); scanf (“\%d”, &Number); for (i = 1; i <= Number; i++) { Factorial = Factorial * i; } printf (“nFactorial of \%d = \%dn”, Number, Factorial); return 0; }
