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:
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;🔍
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⭐
You can access members of a structure using the dot operator (`.`). Here’s how to print out the `student1` information: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
