> 3. The following function supposedly computes the sum and average of the numbers in the array `a`, which has length `n`. `avg` and `sum` point to the variables that the function should modify, unfortunately the function contains several errors, find and correct them.

{
int i;
// This was assigning a pointer to a float,
// the dereference operator was missing
*sum = 0.0;
for (i = 0; i <n;i++)
// This wasn't increasing the value
