What is triple pointer?
Example: int x; -- integer int *px= &x; -- pointer to integer int **ppx= &px; -- pointer to pointer to integer int ***pppx= &ppx; -- pointer to pointer to pointer to integer
C program pointers to pointers examples?
Pointer to Pointer is a double pointer, denoted by (**). Pointer stores the address of the variable and pointer to pointer stores the address of a pointer variable and syntax can be given as int **ptr2ptr;
What is generic pointer in C?
When a variable is declared as being a pointer to type void it is known as a generic pointer. Since you cannot have a variable of type void, the pointer will not point to any data and therefore cannot be dereferenced. It is still a pointer though, to use it you just have to cast it to another kind of pointer first. Hence the term Generic pointer.
When you let your pointer linger over an object the pointer is?
The pointer is non-NULL.
Which two pointer does not increment or decrement in arithmetic array?
constant pointer and character pointer
Which way does a compass needle usually point?
The needle, or "pointer", of a compass will always point North. See: http://en.wikipedia.org/wiki/Compass
Why does compass needle get deflected when brought near a bar magnet?
The needle is always pointing with reference to the poles. When another magnetic field gets close to the pointer, the forces of thos fields collide, and the pointer moves towards the larger field.
What are the 2 different types of torque wrenches?
There are more than 2 types, but the most common 2 have a long pointer needle or a snap ratchet.
Difference between pointer to constant and constant pointer?
1. pointer to a constant means you can not change what the pointer points to 2. constant pointer means you can not change the pointer.
What is triple pointer?
Example: int x; -- integer int *px= &x; -- pointer to integer int **ppx= &px; -- pointer to pointer to integer int ***pppx= &ppx; -- pointer to pointer to pointer to integer
What are pointer to pointer?
A pointer only holds an address information (location) in the memory. if a pointer holds points another pointer then it is a pointer to an other pointer. Pointer holds an address in the memory so in that address there is an other location information that shows another location.
Shifter engages only when arrow is in between letters no noise runs perfect just looks odd and just happened today?
Generally the pointer ["arrow"] is not directly connected to the transmission, and is loosely connected to the shift lever, or its linkage to the transmission, by a very flimsy cable or rod and connectors. The pointer is only a position indicator for the lever. If the transmission is operating properly as you describe, I suspect that the the only problem is that the linkage TO THE POINTER has been damaged or dislocated. Sometimes, if the needle linkage is a small cable, it is routed over a pivot or small pulley. If the cable has been dislocated, it will cause the needle to be dislocated also. j3h.
Can you break a compass with a magnet?
In a compass box we have a small magnetic needle to which an aluminum pointer is attached at right angle. Since it has a magnetic piece, it has to respond to other magnets. In some boxes we have the pointer small in size is itself a magnet pivoted freely.
What is pointer of pointer?
pointer is the variable that holds the address of another variable
Why is double pointer used?
Double pointer is a pointer to a pointer. So you can work with the double pointer as you work with a single one.Or you might mean 'pointer to double', eg:void clear_double (double *dp){*dp = 0;}
Define pointer to pointer in c?
Double (**) is used to denote the double pointer. As we know the pointer stores the address of variable, Double pointer stores the address of any pointer variable. Declaration : int **ptr2Ptr;
What is void pointer and what are its uses?
Void pointer can hold the address of any kind of pointer. But we can't operate on void pointer
