Typedef int Array

typedef is a reserved keyword in the programming languages C and C++. It is used to create an additional name (alias) for another data type, but does not create a new type, except in the obscure case of a qualified typedef of an array type where the typedef qualifiers are transferred to the array element type.

The C language contains the typedef keyword to allow users to provide alternative names for the primitive (e.g.,​ int) and user-defined​ (e.g struct) data types . Remember, this keyword adds a new name for some existing data type but does not create a new type.

The typedef is an advance feature in C language which allows us to create an alias or new name for an existing type or user defined type. The syntax of typedef is as follows: … typedef int myint; Now myint is an alias of int . From now on we can declare new int variables using myint instead of int keyword.

What is typedef in C and C++? As the name itself suggests, typedef stands for “type definition ”. typedef is nothing but a way to assign a new name to a pre-existing data type. In other words, typedef is basically a reserved keyword that we use in order to create an alias name for a specific data type.
