Difference Between Struct and Typedef Struct in C++
The below table demonstrates the key differences between struct and typedef struct in C++ are:
Feature | Struct | Typedef Struct |
|---|---|---|
Definition | Used to define a structure with the struct keyword. | Used to define a structure and create an alias for it. |
Syntax | struct StructName { members }; | typedef struct { members } AliasName; |
Instantiation | Requires ‘struct’ keyword for declaration and instantiation. | Does not require ‘struct’ keyword when declaring objects of the type. |
Purpose | Groups together different data types into a single unit. | Simplifies the syntax for using the structure, reducing code verbosity. |
Usage of Aliases | Cannot directly create an alias for the type name | Allows creating an alias for the type name, improving code readability |
Additional Typedefs | Cannot create multiple typedefs for the same struct | Can create multiple typedefs for the same struct, providing flexibility in naming |
Difference Between Struct and Typedef Struct in C++
In C++, the struct keyword is used to define a struct, whereas the typedef keyword is used for creating an alias(new name) for existing datatypes and user-defined datatypes like class, struct, and union to give them more meaningful names. In this article, we will learn the differences between a struct and a typedef struct in C++.
