A pointer can point to address of another pointer. consider the example
int x=456, *p1, **p2;p1 = &x;p2 = &p1;
Copyright Einstein College of EngineeringDepartment of Civil Engineering

printf("%d", *p1); will display value of x 456.printf("%d", *p2); will also display value of x 456. This is because p2 point p1, and p1 points x.Therefore p2 reads the value of x through pointer p1. Since one pointer is points towards anotherpointer it is called chain pointer. Chain pointer must be declared with ** as in **p2

What is the minimum number of additional pointers will be needed to reverse a singly linked list?
3 pointers...
What are the different pencil pointers?
the different pencil pointers are albert Einstein. Archimedes and some other jinjurikis
In C you use the concept of pointers whereas there are no pointers used in JAVA why?
Pointers in C are generally the thing that gives learners the most trouble. When C code is not written correctly with respect to pointer use, the resulting bugs can often be very difficult to find and correct. On the other hand, pointers are absolutely necessary in some cases.The designers of Java wanted to make programming easier and hence avoided adding pointers to the language. Java does have object references which accomplish much of what pointers accomplish albeit in a safer way.
Do other programming languages implement pointers?
All programming languages implement pointers, but not all languages allow low-level access to memory through a raw pointer. Java, for instance, uses resource handles and smart pointers rather than raw pointers, however the actual allocation of memory is handled by the Java virtual machine (JVM) so there is no need for low-level raw pointers.
What is Arrays of Pointers?
An array of pointers is a contiguous block of memory that contains pointers to other memory locations. They essentially allow non-contiguous memory locations to be treated as if they were an actual array.
What are void pointers?
They are pointers without type
Where the pointers are used?
POINTERS ARE USED TO STORE ADDRESS
What are the background pointers in java?
Java does not support pointers.
Pointers are replaced by what in java?
Nothing. Java does not have a concept that is equivalent to Pointers.
How do you get score 6?
3 two-pointers or 2 three-pointers
Can you use pointers in java?
Java does not support Pointers and hence you cannot use it in Java.
Can labs be trained as pointers?
Yes, some labs are trained as pointers, and some as retrievers.
How many three-pointers did LeBron James make?
he made about 130,000 three pointers
Why laser mouse are used?
Because the laser pointers are much easier to use than the ball pointers. The ball pointers are often difficult to move around while the laser pointers can move in any direction without "getting stuck"
How pointers are used in java?
They aren't. Java uses the (safer) idea of references instead of pointers.
What are restricted pointers in C99?
Using this you specify that two pointers can't point on the same address
What is an array pointers?
I guess it is an 'array of pointers'. Example:int main (int argc, char *argv[])
