C Structure example

This section illustrates you the concept of structure in C.

Structures in C defines the group of contiguous (adjacent) fields, such as records or control blocks. A structure is a collection of variables grouped together under a single name. It provides an elegant and powerful way for keeping related data together.

Structure Declaration:

struct struct-name{
type field-name;
type field-name;
... };

Once the structure is defined, you can declare a structure variable by preceding the variable name by the structure type name. In the given example, a small structure i.e struct is created student and declared three instances of it as shown below.

struct student{
int id;
char *name;
float percentage;
}

In structures, we have assigned the values to the instances i.e, id, name, percentage in the following way:

student1.id=1;
student2.name = "Angelina";
student3.percentage = 90.5;

Here is the code:

STRUCTUR.C


#include <stdio.h>

#include <conio.h>



struct student {

  int id;

  char *name;

  float percentage;

} student1, student2, student3;

int main() {

  struct student st;

  student1.id=1;

  student2.name = "Angelina";

  student3.percentage = 90.5;

  printf(" Id is: %d \n", student1.id);

  printf(" Name is: %s \n", student2.name);

  printf(" Percentage is: %f \n", student3.percentage);

  getch();

  return 0;

}

Output will be displayed as:
