}

Output :

max@ubuntu:~/cprog$ gcc sumArray.c -o sumArray
max@ubuntu:~/cprog$ ./sumArray

= = = = = = Sum of Array elements = = = = =

How many elements you wanna Store : 5

Enter the values into array :
1
2
3
4
5

Sum of all the numbers in the array = 15

= = = = = = = = = = = = = = = = = = = = = = =
