To find the factorial of the entered number

In this programme I have given the concept to find the factorial of the number.
For this we have to know what factorial is:

For example the factorial of 5 is 5*4*3*2*1
The main source code of this programme is given below:

	#include<stdio.h>
	#include<conio.h>
	int main()
	{
	int n,i,fact;
	printf("enter the num whose factorial is to be find");
	scanf("%d",&n);
	fact=1;
	for(i=n;i>=1;i--)
	{
	fact=fact*i;
	}
	printf("factorial of the entered number=%d",fact);
	getch();
	}
