1.Assumethefollowing Ada program was compiled and executed.

procedure Main is

X: Integer;

procedure Sub1 is

begin — of Sub1

Put(X);

end;

procedure

Sub2

is

X: Integer;

begin — of Sub2

X := 10;

Sub1;

end;

begin — of Main

X := 5;

Sub2

end;

a) Using static scoping rules, what is the value of X is printed in procedure Sub1?

b) Under dynamic-scoping rules, what value of X is printed in procedure Sub1?

2. There are five different types of arrays discussed in class: static, fixed stack-dynamic, fixed heap-dynamic, and heap-dynamic. Identify the categories of arrays at positions 1, 2, 3, and 4

Int foo(void) {

Int z[2];——————> 1

Static inta[3] = {3,6,9

}

.——————> 2

Int* b= new int [6];——————-> 3

Vector c;——————-> 4

}

8. Are the tuples of Python mutable?

9. Java is a static-typed language. What does “static-typed language” mean?

10. Compared with C, Java is a strong-typed language. What does “strong-typed language” mean?
