C Program to Find Factorial of a Number.

1.The factorial of a positive integer n is equal to 1*2*3*...5. You will learn to calculate the factorial with recursion of a number using for loop.

For Example-:

	 #include<stdio.h>
 int recursion(int);
	 void main()
	 {
	    int i,n,fact=0;
	    printf("enter the no");
	    scanf("%d",&n);
	    fact=factorial(n);
	    printf("factorial value:%d",fact);
	   
	 }
	 int factorial(int m);
	 {
	    int i,fact=1;
	    if(m==0)
	    {
	    return(0);
	    }
	    else
	    {
	     fact=m*recursion(m-1);
		 {
		  return(fact);
	     }
	    }
	 }
