double factorial(double N)

{

double total = 1;

while (N > 1)

{

total *= N;

N--;

}

return total; // We are returning the value in variable title total

//return factorial;

}

int main()

{

double myNumber = 0;

cout << "Enter the number: ";

cin >> myNumber;

cout << endl << "Factorial of N is: " << factorial(myNumber);

return 0;

}

By the definition of a factorial, multiply all numbers up to the number given.

For example (using Java code):

int number = 5; // Sample value

long factorial = 1;

for (int i = 1; i <= number; i++)

{

factorial *= i;

}

System.out.println(number + "! = " + factorial);

Write a recursive procedure to compute the factorial of a number?

#include &lt;iostream&gt; using namespace std; int main() { int i, number=0, factorial=1; // User input must be an integer number between 1 and 10 while(number&lt;1 number&gt;10) { cout &lt;&lt; "Enter integer number (1-10) = "; cin &gt;&gt; number; } // Calculate the factorial with a FOR loop for(i=1; i&lt;=number; i++) { factorial = factorial*i; } // Output result cout &lt;&lt; "Factorial = " &lt;&lt; factorial &lt;&lt; endl;


Write an algorithm to print the factorial of given number and then draw the flowchart?

write an algorithm to print the factorial of a given number and then draw the flowchart. This looks like someones homework, defiantly someone looking for the easy way. When it comes to programming, the more you do the better you get. Experience counts (making your own mistakes and learning from the mistake).

How do you create factorial program in qbasic?

since factorial is for example , the factorial of 5 = 5 (5-1)(5-2)(5-3)(5-4) that means the last number to subtract from 5 is 4 , which is (n-1) ie the factorial of any number is (n-0)(.............)(n-(n-1)) to write this , 5 REM to calculate the factorial of any number 6 DIM fac AS INTEGER LET fac = 1 10 INPUT "enter the number to find its factorial "; a ' variable a 15 FOR b = 0 TO (a-1) 'numbers that will be subtracted from the " a" 20 c= a -b 'each number in the factorial calculation 25 fac = fac * c 'to compute each multiplication in the factorial 30 NEXT b 35 PRINT 'to leave a line 40 PRINT fac 45 END note this due to some unattained raesons works for numbers 0 to 7

How do you calculate factorial without calculator?

Factorial is calculated by taking the number and multiplying it continually by 1 less than that until you finally multiple by 1. For example 6! = 6x5x4x3x2x1 = 720


What is factory or factorial?

Factorial for number N is N x N-1 x N-2 X N- (N-1). e.g. if you need to calculate factorial for 5 then compute 5 x 4 x 3 x 2 x 1.

What is a program in c to calculate factorial of number?

First of all we will define what factorial is and how to it is calculated.Factional is non negative integer. Notation would be n! It is calculated by multiplying all integers from 1 to n;For example:5! = 1 x 2 x 3 x 4 x 5 = 120.Note: 0! = 1Small C program that illustrates how factorial might be counted:#include int factorial(int num);int main() {int num;printf("Enter number: ");scanf("%d", &num);printf("Factorial: %d\n", factorial(num));return 0;}int factorial(int num) {if (num == 0) {return 1;}return num * factorial(num - 1);}Testing:Enter number: 5Factorial: 120Enter number: 0Factorial: 1

Find factorial at given number using do while loop?

Actually, a for loop is more appropriate in this case. With while, it would be something like the following pseudocode - adapt to your favorite programming language:function factorial(n)result = 1factor = 1while factor
