Answer 1

ANSWER:-

QUESTION (1):-

15                   // first print value of b is locally because b is declare locally and globally both but in the main               function b declare is locally so will not access globally value of b so print 15

40             // in function b does not hold any local value so access globally and print 40

7                  //   A-function call with the value 7 so in function body check if statement , if statement true so return 7 and print 7 in main function

QUESTION (2):-

-11 9            //  after function calling swap the value and print the result -11  9
-11 9           //  in main function print same result because function call with reference so changes will be parmanent after function calling
