* This question tests your understanding of the difference between static and dynamic scoping. Consider the following program (using C's syntax): #include int x, y: void foo () printf("foo y - %d ", y); void bar (int y){ printf("bar x = %d ", x); printf("bar y = %d ", y); foo(); int main() x = 40; y = 20; printf("main y = %d ", y); bar (17); foo(); return 0; (a) What does the program print under static scoping? (b) What does the program print under dynamic scoping
