Simple Structure Example Program

About this program

This is an example program in c structure and union programs. Read the concept first: C Structures, then study the code and output below.

Definition

• C Structure is a collection of different data types which are grouped together under a common name.
• Each element in a Structure is called structure member variables.
• Structure member variables may in same or different datatypes.

Syntax:

struct tag_name {
   type member1;
   type member2;
   /* declare as many members as desired*/
};

Simple Structure Example Program

/*##Simple Structure Example Program with declaration,assign and Print Values*/
/*##Simple Structure Programs,strcpy Example*/

#include <stdio.h>
#include <string.h>
 
// Define Strcutre 
struct student 
{
           int id;
           char name[20];
           int mark;
};
 
int main() 
{
	// Declare Strcutre Variable
	struct student record;
 
	// Assign Values for Strcutre Memebrs : id,name and mark
	record.id=1001;
	
	// Assign Values name using strcpy function;
	strcpy(record.name, "Balan");    
	record.mark = 89;
 
	// Print Strcutre Memebrs Values
	printf("Student Id   : %d \n", record.id);
	printf("Student Name : %s \n", record.name);
	printf("Student Mark : %d \n", record.mark);
	
	return 0;
}

Sample Output:

Student Id   : 1001 
Student Name : Balan 
Student Mark : 89

How It Works

This C program demonstrates Simple Structure. It first prepares the data it needs, then performs the core operation step by step, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
