The document provides a C program to calculate the factorial of a given number, illustrating that the factorial of n is the product of all positive descending integers. It includes code that prompts the user to enter a number, calculates the factorial using a loop, and then outputs the result. For example, when inputting 5, the program outputs 'factorial of 5 is 120'.

Factorial Program in C
Factorial of n is the product of all positive descending integers. For example:
5! = 5*4*3*2*1 = 120. Here we write Factorial Program in C
#include<stdio.h>
#include<conio.h>
void main()
{
int fact,i,n;
fact = 1;
printf("Enter any Number: ");
scanf("%d" , &n);
for(i = 1; i <= n; i++)
{
fact = fact*i;
}
printf("Factorial of %d is %d", n , fact);
getch();
}
Output:
Enter any Number: 5
Factorial of 5 is 120
