Typedef in Structure Declaration in C

In this method, the declaration starts with typedef followed by key word struct. The data members of the structure are placed between a pair of curly braces after struct. The type name is placed after the closing right brace (}). This is explained in the following example:

typedef struct

{

  int datamemberl;

  int datamember2;

  int datamember3;

} type_name ;

Program provides an illustration of the typedef method where a structure with type-name vector is declared. Any instance of the structure may be declared as given below.

Illustrates typedef method for declaring structures

# include <stdio.h> 
 typedef struct 
 { 
 int x; 
 int y; 
 int z; 
 } vector; 
 void main () 
 { 
   vector A= {5,8,7}; 
   vector B = {6} ; 
   vector C = {4,8}; 
   clrscr(); 
   printf("A.x = %d \tA.y = %d \tA.z = %d", A.x, A.y, A.z); 
   printf("\nB.x = %d \tB.y = %d \tB.z = %d", B.x, B.y, B.z); 
   printf("\nC.x = %d \tC.y = %d \tC.z = %d", C.x, C.y, C.z); 
   printf ("\n"); 
 }
