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;
A pointer which keeps address of a function is known as function pointer. example: { void *(*ptr)(); ptr= &display; (*ptr)(); return(0); } void display() { .................. )
Yes. Examples can be found in stdio.h
a pointer is a derived data type in c. pointers are undoubtedly one of the most distinct and exciting features of c language.it has added power and flexibility to the language. *pointers are more efficient in handling arrays and tables. *pointer can be used to support dynamic memory management. *pointers reduce length and complexity of programs. *increase the execution speed and thus reduce the program execution time. by following character's real power of c lies in proper use of pointers. pointer is called the jewel of c-language.
They don't.
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.

Java doesn't have pointers. C++ has pointers.

mystrcpy (char* dest, char* src) { while ((*dest++ = *src++) != '\0); }
They don't.
C does not have stream pointers.
