3. Write the appropriate function definition for each of the following situations:
a) Write a function that separately sums the even indexed elements and old

indexed elements of an array of doubles. Each element of the array

contributes to one of the two sums, depending on whether the index of the

element is even or odd. Your function definition must have a heading like

this:
void sum(double b[ ])
{ int n;
double *sum_even;
double *sum_odd;
:
:
}
