Structures

Structure is a user-defined data type which consists of a bunch of variables -- see picture below:

 

 

 

 

Here's how you'd create a structure in MATLAB:

 » Case.Name = 'Jack';
» Case.ID = '123456';
» Case.Status = 'Open-Pending Research';

» Case

Case =
Name: 'Jack'
ID: '123456'
Status: 'Open-Pending Research'

Name Size Bytes Class

Case 1x1 434 struct array

Grand total is 34 elements using 434 bytes

Here's how you'd do it in C: 


#include 
 
struct Case
{
  	char Name[100];
  	int  CaseID;
  	char CaseStatus[100];
};
 
void main( )
{
  	char *dummyname   = {"Jack"};
  	int  dummyid              = 123456;
  	char *dummystatus  = {"Open-Pending Research"};
	 
  	struct Case *MyCase;
	 
  	MyCase = (struct Case *)malloc(sizeof(struct Case));
	 
  	strcpy(MyCase->Name, dummyname);
  	MyCase->CaseID = dummyid;
  	strcpy(MyCase->CaseStatus, dummystatus);
	 
  	printf("Contact Name: %s\n", MyCase->Name);
  	printf("Case ID     : %d\n", MyCase->CaseID);
  	printf("Case Status : %s\n", MyCase->CaseStatus);
	 
  	free(MyCase);
}

Let's take a closer look at the above C-code
