JAVA TEST PAPER 2 Technical questions 1.output of the following code:    #define M 5+5    void main()   { printf(“%d”, M*M);    } 2.*p+ + increment p or what it points to?  3.Find error with a given code:    {scanf("&",a)} 4.syntax of free func.  5.give output:    void main()   {     int x=0, y=1;   (x || printf(“printing xn”));   (y|| printf(“printing yn”));    } 6 write one major advantage & disadvantage of recursion. 7.what is hashing? 8. give output:     main()    {    int j=5;    printf(“%d %d %d”, + +j, j, j+ +);    } 9.give output:   main()   {   int static i=5, j=10;   for(i=1;i<=3;i++)   {   int j=10; j=j+1;   printf(“%d %d %d” j, j, j);   }   printf(“%d”, i);   } 10. why printf(“%d”, ‘A’); will not return the value 1? 11. preorder and postorder traversal of a binary tree is given, construct the binary tree. 12. a binary tree is given, draw postorder traversal. 13. what is the difference between char const* , char *const ? 14. correction of a given code 15. write a macro function to return the maximum of two numbers. 16. how a pointer to a function is called & declared? 17 write a program for double linked list & delete the last node. 18. write a program for binary search of N numbers. 19. program related to string.
