What is type struct

What is type struct ?

Type variable // we change the type

Code:

---

type integer    int x    // x store integer value x = 12

type charactr  char y  // y store charactr value y = 'K'

type float      float z    // z store floating value z = 11.09

type struct ?

A struct type is a type that can be used to group objects of various types together into a single object.

I did not understand the meaning of your definition. It would be better to prove your definition by example

You can find such examples in any good introductory C textbook.

Nonetheless, here is an example:

Code:

---

struct X
{
    int a;
    float b;
};

---

Then using the notation you used in post #1:

Code:

---

type struct X      struct X w    // w store integer value w.a = 12 and floating value w.b = 11.09

point type integer int *a
point type charactr char *b
pointer type float float *c

What is pointer type struct

struct X * v;

Does the pointer point to the structure object v


Does the pointer point to the structure name X

The pointer is named v.

C programmers often loosely use the word "struct" or "structure" to mean an object of struct type. In your example, there is no such object. struct X refers to the type, not the object.

What material are you using to learn C?

k&r c programming

Code:

---

struct X{
  int a;
  int b;
}


int main ()
{
  struct X * v;


    v->a ; v is pointer and a is structure object
    v->b ; v is pointer and b is structure object
   
    return 0;
}

If you're having difficulty understanding K&R, then put it aside for now and reach for a beginner's introductory book rather than an experienced programmer's introductory book.

What does the term "structure object" mean to you?

Structure is a group of different data types and each element in a C structure is called member

type int store integer value x = 12
type char store charactr value y = 'K'
type float store floating value z = 11.09

It stores an aggregate of types
