Given an array, write a program to find the sum of array using pointers arithmetic.
In this program we make use of * operator . The * (asterisk) operator denotes the value of variable. The * operator at the time of declaration denotes that this is a pointer, otherwise it denotes the value of the memory location pointed by the pointer .
sum() function is used to find the sum of the array through pointers.
Input : array = 2, 4, -6, 5, 8, -1 Output : sum = 12 Input : array = 1, 4, -6, 8, -10, -12 Output : sum = -15
sum of array is = 12
