Program for factorial of a number

Factorial of a non-negative integer, is multiplication of all integers smaller than or equal to n. For example factorial of 6 is 6*5*4*3*2*1 which is 720.

Sum of all Array elements means add all array Elements. Suppose we have 4 Elements in array and we want to find there sum.

arr[0]=4

arr[1]=2

arr[2]=1

arr[3]=6

Sum off all above elements are

arr[0]+arr[1]+arr[2]+arr[3]=4+2+1+6=13
