What is Structure in C language | What is User Define Data Type in C | Structures in C with Examples
In C language, a structure is a composite data type that allows you to group variables of different data types under a single name. Structures are used to create user-defined data types that can represent a collection of related data elements.
To define a structure in C language, you use the "struct" keyword followed by the name of the structure, and then you define the variables inside the structure using any valid C data type.
The syntax for defining a structure in C language is as follows:
struct [structure_name] {
data_type member1;
data_type member2;
.
.
.
data_type memberN;
}[object];
Here, "struct" is a keyword in C language that indicates the start of a structure definition. "structure_name" is the name of the structure that you want to define. Inside the curly braces, you define the members of the structure, which can be of any valid data type in C language.
For example, if you want to define a structure called "book" that has members for the title, author, and price of a book, you would use the following syntax:
struct book {
char title[50];
char author[50];
float price;
};
In this example, we have defined a structure called "book" that has three members - a character array named "title", a character array named "author", and a floating-point variable named "price".
Once you have defined a structure, you can declare variables of that structure type as follows:
struct book b1, b2;
In this example, we have declared two variables of type "book" called "b1" and "b2". You can then access the members of the structure using the dot (.) operator.
For example:
strcpy(b1.title, "The Catcher in the Rye");
strcpy(b1.author, "J.D. Salinger");
b1.price = 9.99;
printf("Title: %s\n", b1.title);
printf("Author: %s\n", b1.author);
printf("Price: %.2f\n", b1.price);
In this example, we have assigned values to the members of the "b1" variable and then printed those values using printf statements.
Structures in C language have several uses, including:
Organizing complex data: Structures provide a way to organize multiple data elements of different data types into a single unit. This is especially useful when dealing with complex data that has many different fields or properties.
Creating user-defined data types: Structures allow you to create custom data types in C language, which can simplify program development by providing more meaningful and descriptive names for data elements.
Passing data between functions: Structures can be used to pass multiple data elements between functions as a single parameter, which can simplify function calls and make code more readable.
Representing real-world objects: Structures can be used to represent real-world objects, such as employees, cars, or books, and their properties. This can make it easier to write programs that model real-world scenarios.
Creating data structures: Structures can be used to create more complex data structures, such as linked lists, stacks, and queues. This can make it easier to manage large amounts of data in a program.
Overall, structures provide a powerful and flexible way to organize and manipulate data in C language. They are an essential tool for writing efficient and well-organized code in C.
