Use program Differences for Exercises 5 and 6.
// Program Differences is for investigating the differences
// between automatic and static variables.
#include <iostream>

/* TO BE FILLED IN */
}
Exercise 5:
Function TestLocals defines a local variable, count, and initializes it to 1. The contents of count are
incremented and sent to the output stream. Write this code and run program Differences. Record your
output. Was it what you expected?
Exercise 6:
Change function TestLocals so that local variable count is a static variable. Rerun your program and
show your output. Was it what you expected? Based on your observation from Exercise 5 and 6, explain
the difference between automatic and static variables.
