Is the following statement a declaration or definition?
extern int i;

Options
1) Declaration
2) Definition
3) Function
4) Error

• see at the stmt int *ptr=(int*)malloc(sizeof(int)); here malloc will request for memory of size int if its request is granted than that size of block assigned to ptr variable..not *ptr=4; *ptr has value 4 now next line printf("%d",(*ptr)+++*ptr++); see how it will be solve (4++ + 5++) i just puted the corresponding values... it will be solved as 4+5(will dicard last post increment )
  so ans should be (b) ie 9
