Lesson 4

Structures

Create complex data types

1What is a Structure?✨

In C, a structure is a user-defined data type that allows you to combine different data types into a single unit. This is especially useful when you want to group related data together.

2Why Use Structures?🎯

  • ✓ Organize complex data
  • ✓ Improve code readability
  • ✓ Create custom data types
  • ✓ Simplify function parameters

3Creating a Structure💡

To create a structure, you use the `struct` keyword followed by the structure name and its members. Here's a simple example:

💻 code
struct Student {
    char name[50];
    int age;
    float grade;
};

This defines a `Student` structure with a name, age, and grade.

4Using Structures🚀

Once you've defined a structure, you can create variables of that type. Here's how to create and use a `Student`:

5struct Student student1;🔍

💻 code
strcpy(student1.name, "Anjali");
student1.age = 16;
student1.grade = 88.5;

This creates a `student1` variable and assigns values to its members.

6Accessing Structure Members⭐

💻 code
You can access members of a structure using the dot operator (`.`). Here’s how to print out the `student1` information:
💻 code
printf("Name: %s\n", student1.name);
printf("Age: %d\n", student1.age);
printf("Grade: %.2f\n", student1.grade);

This will display the student's details on the screen.

7What You'll Build This Grade🧩

  • ✓ Programs that manage student records
  • ✓ Applications for library management
  • ✓ Games with complex character data
  • ✓ Real-world simulations with structured data
