Note: The recursive portions of this code can use a lot of stack space. You may need to tell your linker to allocate more space to prevent a stack overflow exception.
To calculate the factorial of a user given number, simply multiply all of the integers between 2 and that number, inclusive, together. There are two fundamental algorithms; iterative and recursive...
Iterative uses a loop of some sort to iterate through each multiplier and multiply that to the running product.
These examples were developed and checked on the Microsoft Windows SDK 7. Portable compilers might not like the 64-bit long long data type.
/* Microsoft 32-bit iterative */
unsigned long NFactLongIterative (unsigned long N) {
unsigned long result = N;
if (N < 2) return 1;
if (N 2) {
decimal_initialize (d, 2);
return;
}
while (N > 2) {
decimal_multiply (d, N);
N--;
}
return;
}

What is the most efficient way to implement a factorial algorithm in a programming language?
The most efficient way to implement a factorial algorithm in a programming language is to use an iterative approach rather than a recursive one. This involves using a loop to multiply the numbers from 1 to the given input number to calculate the factorial. This method is more memory-efficient and faster than using recursion.

How many diagonals do hexagons have?
The number of diagonals in an n-sided polygon is given by nC2 - n (where n is the number of sides of the polygon) or in the expanded form: factorial (n) _______________________ {factorial (2) * factorial (n-2)} substituting (n = 6) for a hexagon we get the number of diagonals as 9. Similarly, substituting (n=5) for a pentagon we get the number of diagonals as 5.

Program for calculating factorial no using recursion in c?
factorial n is given by formula n! = n.(n-1)....1 int i; long x; x =1; for (i=n;i>1;i--) x = x*i ; will calculate factorial. I have put x as long to avoid integer overflow. checks for n is positive etc. to be added.
