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
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;
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.
constant pointer and character pointer
The pointer is non-NULL.
yea that's why its called the point FINGER
It is to show you that the pointer is on the zero mark.
The function of a pointer tells you if you have the correct measurement or not. hope that helped!!:)xoxox <3 -Demi
There is no specific key. Put your mouse pointer on the sentence and triple-click.
When after you adjust the riders and the pointer reads zero
use the silver knob on the right side of your triple beam balance until the pointer in the middle indicates that both sides are balanced
There are many parts to this triple-beam balance scale....there is the Balance pan were you put the object you are measuring then the riders and the beams and the riders ride on the beams then the zero then the arm the pointer end the base the fulcrum and the tare but it is used to adjust the pointer that points to the zero and that is all.

The triple beam balance consists of three main parts: the pan, the beams with riders, and the pointer. The pan is where the object to be weighed is placed. The beams have riders that are moved to balance the weight, while the pointer indicates the weight measurement.
The parts of a triple beam balance include the base, the three weighted beams (each marked with different increments), the zero adjust knob for calibration, the pan where objects are placed for weighing, and the pointer that aligns with the scale to indicate the weight of the object.
It is called "zeroing" the balance. This process ensures that the pointer is accurately aligned with the zero mark, which is the starting point for measurements on the balance.
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.
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.
