Arithmetic can be performed on pointers. However, in pointer arithmetic, a pointer is a valid operand only for the addition(+) and subtraction(-) operators. An integral value n may be added to or subtracted from a pointer ptr. Assuming that the data item that ptr points to lies within an...
A nil pointer is a false value. For example, 1 > 2 is a nil statement. In the programming languageC, NULL is an available command that can be used, whereas nil is an available command used in thePascalprogramming language. Memory leak,Memory terms,NULL,Pointer,Programming terms,Segmentation...
Such a variable is called apointer variable(for reasons which hopefully will become clearer a little later). In C when we define a pointer variable we do so by preceding its name with an asterisk. In C we also give our pointer a type which, in this case, refers to the type of data ...

What happens if we use an uninitialized array in C language?If we use any uninitialized array in C program, compiler will not generate any compilation and execution error i.e. program will compile and execute properly.If the array is uninitialized while declaring and even after the declaration ...
What is a structure in C programming language? In C++, create a class called MyInteger. It should have a field of type pointer-to-int called pInteger. It should have a constructor that takes as a parameter an int - the constructor will then dynami ...

That is implementation specific, and you won't be able to see the representation ofnullin a pure Java program. (Butnullis represented as a zero machine address / pointer in most if not all Java implementations.) 意思是这个跟Java语言无关,是由Java实现自己去决定的,但大多数实现都是把它放在了...
