Typedefs A typedef declaration introduces a name that, within its scope, becomes a synonym for the type given by the type-declaration portion of the declaration. You can use typedef declarations to construct shorter or more meaningful names for types already defined by the language or for types that you have declared.

The only purpose of typedef is increased program clarity. typedef can be used to rename any data type including enum and struct definitions, which we will study shortly. Example of typedef in C Now that it is pretty clear as to what typedef is, let us consider a simple problem at hand to acknowledge its significance. Suppose, we are expected to create a structure named student with details such as name and age, instead of writing the keyword struct followed by its structure name, we could use an alternative name in order to maintain the clarity of the code. C Tutorial – structures, unions, typedef In the C language structures are used to group together different types of variables under the same name. For example you could create a structure “telephone”: which is made up of a string (that is used to hold the name of the person) and an integer (that is used to hold the telephone number). During your programming experience you may feel the need to define your own type of data.
One of the important features of ‘typedef’ is that it allows the programmer to encapsulate the details of implementation that may change over time. C语言允许用户使用 typedef 关键字来定义自己习惯的数据类型名称，来替代系统默认的基本类型名称、数组类型名称、指针类型名称与用户自定义的结构型名称、共用型名称、枚举型名称 このページではC言語における typedef について解説します。 多くの具体例を踏まえて解説していますので、是非実際の使い方と一緒に typedef の使い方や効果を理解・実感していただければと思います！ スポンサーリ In C programming language, typedef is a keyword used to create alias name for the existing datatypes. Using typedef keyword we can create a temporary name to the system defined datatypes like int, float, char and double.
In the context of C programming, this article explains how the enum keyword allows meaningful names to be used instead of integer values to index a collection
It basically introduces a name that becomes the synonym of the given type using the type declaration within that scope.

C Tutorial – structures, unions, typedef. In the C language structures are used to group together different types of variables under the same name. For example
In this tutorial, we will discuss: The typedef keyword allows us to rename a data type to a name that has more meaning to our program. The only purpose of typedef is increased program clarity. typedef can be used to rename any data type including enum and struct definitions, which we will study shortly. The typedef declaration provides a way to declare an identifier as a type alias, to be used to replace a possibly complex type name The keyword typedef is used in a declaration, in the grammatical position of a storage-class specifier, except that it does not affect storage or linkage: typedef names for structs could be in conflict with other identifiers of other parts of the program.
