Typedef in C

A typedef is a mechanism in C that allows you to create new types based on existing types. This means you can define a new type with the same name and members as an existing type, but with different types for different data types.

Benefits of Typedef:

Code reusability: You can reuse existing types in multiple parts of your code without having to rewrite them from scratch.
Improved readability: Using typedef can make your code more readable and easier to understand.
Enhanced type safety: Typedef can help to prevent errors by ensuring that you are using the correct type of data in the correct context.

Example:

typedef struct Student {

char name[50];

int age;

float marks;

} Student;

This typedef defines a new type called Student that is based on the existing type struct Student. The Student type has three members: name, age, and marks.

Usage:

Once a typedef has been defined, you can use the new type name instead of the original type name. For example:

Student student;

student.name = "John";

student.age = 18;

student.marks = 90.5;

This code creates a Student object named student with the name "John", age 18, and marks 90.5.
