How do you represent a node in a singly linked list?
One of many possible examples: struct linked_list_node { int data; struct linked_list_node *next; };
What is the difference between declaring variable and initializing variables?
Actually, there is a third step, call definition. Declaration is a statement to the compiler of what type an identifier is, definition is the allocation of memory for that identifier, and initialization is the assignment of an initial value to that identifier. Usually, declaration and definition are done together, but you can also add initialization in that step if desired. int a; /* declaration and definition */ a = 1; /* initialization */ int a = 1; /* declaration, definition, and initialization */ For the case of seperate declaration and definition, consider the struct... struct _mystruct { int a; }; /*declaration */ struct _mystruct mystruct; /* definition */ struct _mystruct { int a; } mystruct; /*declaration and definition */ Note: To be more precise: struct _mystruct; /* struct declaration */ struct _mystruct { int a; }; /* struct definition */ typedef struct _mystruct MYTYPE; /* type definition */ extern struct _mystruct mystructvar; /* variable declaration */ struct _mystruct mystructvar; /* variable definition */ struct _mystruct mystructvar = {7} ; /* variable definition with initialization */ struct _mystruct { int a; } mystruct; /* struct definition and variable definition */ extern struct _mystruct { int a; } mystruct; /* struct definition and variable declaration */
What is the difference between class and struct?
The struct type is suitable for representing lightweight objects such as Point, Rectangle, and Color. Although it is possible to represent a point as a class, a struct is more efficient in some scenarios. For example, if you declare an array of 1000 Point objects, you will allocate additional memory for referencing each object. In this case, the struct is less expensive. When we create a struct object using the new operator, it gets created and the appropriate constructor is called. Unlike classes, structs can be instantiated without using the new operator. If you do not use new, the fields will remain unassigned and the object cannot be used until all of the fields are initialized. It is an error to declare a default (parameterless) constructor for a struct. A default constructor is always provided to initialize the struct members to their default values. It is an error to initialize an instance field in a struct. There is no inheritance for structs as there is for classes. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Structs, however, inherit from the base class Object. A struct can implement interfaces, and it does that exactly as classes do. A struct is a value type, while a class is a reference type.
How does the root struct in destruction help you understand?
What does struct mean in in
What is the meaning of the word struct?
"struct" is not a word.
Is there a limit to nesting of structure?
Yes: only completely defined structured can be included (that doesn't include the actual structure itself). Example: struct a; struct b { int b1; }; struct c { struct a; /* BAD */ struct b; /* OK */ struct c; /* BAD */ };
Similarities between C plus plus struct and class?
The only difference between a struct and a class in C++ is that struct members are public by default while class members are private by default. Other than that they act and behave in exactly the same way and are both used to define classes. By convention, struct is used exactly as it would be used in C, with all public members and no member functions, to provide backward compatibility with C-style code.
The linked list that does not contain NULL pointers?
What is your question about it?It is quite possible, for example if it is a circular list, having a 'sentinel' node.typedef struct ListE {struct ListE *next;...} ListE;ListE listhdr;listhdr.next = &listhdr; /* empty list */
Draw the node single linked list and double linked list?
typedef struct ListNode {struct ListNode *next;anytype data;} ListNode;typedef struct BiListNode {struct BiListNode *next;struct BiListNode *prev;anytype data;} BiListNode;
Can structures be nested in c?
yes. struct a { int x; int y; } struct b{ int z; struct a w; }
Demonstrate single inheritance in C plus plus?
struct base1 { // ... }; struct base2 { // ... }; struct derived1 : public base1 // single inheritance { // ... }; struct derived2 : public base1, public base2 // multiple inheritance { // ... };
Can a Structure contain a Pointer to itself?
Yes, it is quite common. Example: struct List { struct List *Next; int value; } typedef struct List List; Example2: typedef struct Tree Tree; struct Tree { Tree *left,*right; int value; };
