16.What would be the output of the following program.

                        main()

                        {

                            int i=7;

                            printf("%d\n",i++*i++);

                        }

           (a) 49                           (b) 56                           (c) 72                           (d) compilation error

17. What will the printf print?

                        main()

                        {

                            char *p,*f();

                            p=f();

                            printf("f() returns:%s\n",p);

                        }

                        char *f()

                        {

                            char result[80];

                            strcpy(result,"anything will do");

                            return (result);

                        }

           (a) f() returns: anything will do                           (b) f() returns:

           (c) compilation error                                         (d) The printf statement is not going to be executed

18.How many times the following program would print 'Jamboree'?

                        main()

                        {

                            printf("\n Jamboree");

                            main();

                        }

           (a) infinite number of times                                   (b) 32767 times

           (c) 65535 times                                                   (d) till the stack does not overflow

19.Notice the error in the default statement in the code snippet below.Will it give a compilation error?

                        main()

                        {

                            int a=10,j;

                            j=fn(a);

                            switch(j)

                            {

                                case 30: printf("the value is 30");

                                              break;

                                case 50: printf("the value is 50");

                                              break;

                                default:printf("the value is not 30 or 50");

                            }

                        }

                        fn(int a)

                        {

                            return (++a);

                        }

          (a)  Will display "the value is 30"                      (b) Will display "The value is not 30 or 50"

          (c) Yes a compilation error would happen

          (d) No compilation errors but there will be no output on the screen

20.What would be the output of the following program.

                        main()

                        {

                            struct emp

                            {

                                char name[20];

                                int age;

                                float sal;

                            };

                            struct emp e = {"tiger"};

                            printf("\n %d %f",e.age,e.sal);

                        }

          (a) 0    0.000000               (b) Garbage values               (c) Error               (d) none of the above
