The following two exercises relate to Jensens device and pass by name, as discussed in Section 10.3.4.

(a) Write a function that uses Jensens device and pass by name to compute the scalar product of two vectors declared as integer arrays with the same number of elements.

(b) The following sum procedure (in C syntax) was used as an example of pass by name and Jensens device at the end of Section 10.3.4:

int sum (int a, int index, int size) { int temp = 0; for (index = 0; index < size; index++) temp += a; return temp; }

Rewrite this code using a function parameter for the parameter a to imitate pass by name, so that it actually executes like pass by name in C.
