factorial using recursion style in c++ is
unsigned int fact(unsigned int a)
{
if (a<=1)
return 1;
else
{
f*=fact(a-1);
return a;
}
}
when using looping structure factorial is
unsigned int fact (unsigned int n)
{
unsigned int i,f=1;
for(i=1;i<=n;i++)
f*=i ;
return f;
}
Pseudo code+factorial
If you really wanted to do this, you could simulate multiplication with repeated addition.
Factorial (n) = n * Factorial (n-1) for all positive values n given Factorial (1) = Factorial (0) = 1. Pseudo-code: Function: factorial, f Argument: positive number, n IF n<=1 THEN RETURN 1 ELSE RETURN n * f(n-1) END IF
by this program you can find the factorial: #include<iostream> using namespace std; main() { int n,x,f=1; cin>> n; x=0; while(x<n) { x++; f= f*x; } cout<<"factorial is"<<f<<"\n"; system("pause"); return 0; }
A flowchart for factorial of number can be made using different software's. Microsoft Word is the most popular software for beginners to make simple flowcharts.In order to draw the flowchart write the number at the top of the paper and then draw two lines under it going slightly to the sides. Decide what two numbers can be multiplied to equal that number. Keep going until you can no longer get to smaller numbers.
A flowchart to find the factorial of a given number typically includes the following steps: Start, read the input number, check if the number is less than 0 (return an error for negative numbers), initialize a result variable to 1, and then use a loop to multiply the result by each integer from 1 to the input number. The algorithm can be summarized as follows: if ( n ) is the input number, initialize ( \text{factorial} = 1 ); for ( i ) from 1 to ( n ), update ( \text{factorial} = \text{factorial} \times i ); finally, output the factorial.

Using the Euclidean algorithm
To find the factorial of each element in an array using pointers in C, you can create a function that takes a pointer to the array and its size as parameters. In the function, iterate through the array using pointer arithmetic, calculating the factorial for each element and storing the result back in the same array or a separate array. For calculating the factorial, you can use a simple loop or recursion. Finally, print or return the modified array with the factorials.
Note: You may need a larger data type, factorials become very big very quickly and may cause an overflow long factorial(int x) { if(x == 1) return 1; . return((long) factorial(x-1) * x);
Here's a simple Java program to find the factorial of a given number using a recursive method: import java.util.Scanner; public class Factorial { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("Enter a number: "); int number = scanner.nextInt(); System.out.println("Factorial of " + number + " is " + factorial(number)); } static int factorial(int n) { return (n == 0) ? 1 : n * factorial(n - 1); } } This program prompts the user for a number and calculates its factorial recursively.
Yes. But why?
Pseudo code+factorial
#include #include using std::cin;using std::cout;using std::endl;using std::tolower;long factorial(const int& N);int main(){int N = 0; //factorial of Nchar command = 'n';do{cout > N;cout
