9.4 Consider the following (erroneous) program in C: void foo int i; printf ("%d ", i++); int main) int j; for (j = 1; j ?= 10 ; j++) foo(); Local variable i in subroutine foo is never initialized. On many systems, however, the program will display repeatable behavior, printing 0 1 2 3 4 5 6 7 8 9. Suggest an explanation. Also explain why the behavior on other systems might be different, or nondeterministic
