Structure In C

Topics: Structure Using C

What is Structure

Structure in c is a user-defined data type that enables us to store the collection of different data types. Each element of a structure is called a member.

struct keyword is used to define the structure. Let's see the syntax to define the structure in c.

1. struct structure_name

2. {

3. data_type member1;

4. data_type member2;

5. .

6. .

7. data_type memeberN;

8. };

Let's see the example to define a structure for an entity employee in c.

1. struct employee

2. { int id;

3. char name[20];

4. float salary;

5. };

Here, struct is the keyword; employee is the name of the structure; id, name, and salary are the members or fields of the structure.

Declaring structure variable

declare variable at the time of defining the structure.

1. struct employee

2. { int id;

3. char name[50];

4. float salary;

5. }e1,e2;

C Structure example

1. #include<stdio.h>

2. #include <string.h>

3. struct employee

4. { int id;

5. char name[50];

6. }e1; //declaring e1 variable for structure

7. int main( )

8. {

9. //store first employee information

10. e1.id=101;

11. strcpy(e1.name, "Sonoo Jaiswal");//copying string into char array

12. //printing first employee information

13. printf( "employee 1 id : %d\n", e1.id);

14. printf( "employee 1 name : %s\n", e1.name);

15. return 0;

16. }

Output:

employee 1 id : 101

employee 1 name : Sonoo Jaiswal

Functions In C : Important Concept

Topic: Functions In C

A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions.

You can divide up your code into separate functions. How you divide up your code among different functions is up to you, but logically the division is such that each

A function declaration tells the compiler about a function's name, return type, and parameters. A function definition provides the actual body of the function.

The C standard library provides numerous built-in functions that your program can call. For example, strcat() to concatenate two strings

Defining a Function

The general form of a function definition in C programming language is as follows −

return_type function_name( parameter list ) {

body of the function

}

A function definition in C programming consists of a function header and a function body. Here are all the parts of a function −

· Return Type − A function may return a value. The return_type is the data type of the value the function returns. Some functions perform the desired operations without returning a value. In this case, the return_type is the keyword void.

· Function Name − This is the actual name of the function. The function name and the parameter list together constitute the function signature.

· Parameters − A parameter is like a placeholder. When a function is invoked, you pass a value to the parameter. This value is referred to as actual parameter or argument. The parameter list refers to the type, order, and number of the parameters of a function. Parameters are optional; that is, a function may contain no parameters.
