This lab is an exercise with pointer arithmetic. Question 2 of the lab exercise is taken from exercise 17 in Chapter 12 of our textbook: C Programming Language: A Modern Approach (Second Edition), by K. N. King.
1. Rewrite the following function to use pointer arithmetic instead of array subscripting. (In other words, eliminate the variables i and all of the [] operators.) Note that for any array a, the expression a[i] is equivalent to *(a+i).
int sum_array(const int a[], int n)
{
int i, sum = 0;
for (i = 0; i < n; i++)
sum += a[i];
return sum;
}
