All typedef does is allow you to add a name to an existing type.

Structures and unions will give you the chance to store non-homogenous data types into a single collection. Declaring a new data type typedef struct student_structure{ char* name; char* surname; int year_of_birth; }student; PLEASE don't typedef structs in C, it needlessly pollutes the global namespace which is typically very polluted already in large C programs. Also, typedef'd structs without a tag name are a major cause of needless imposition of ordering relationships among header files. 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.

typedef can be used to rename any data type including enum and struct definitions, which we will study shortly. The typedef specifier, when used in a declaration, specifies that the declaration is a typedef declaration rather than a variable or function declaration. Typically, the typedef specifier appears at the start of the declaration, though it is permitted to appear after the type specifiers, or between two type specifiers.

Following is an example to define a term BYTE for one-byte numbers − typedef unsigned char BYTE; After this type definition, the identifier BYTE can be used as an abbreviation for the type unsigned char, for example..

It is mostly used with user-defined datatypes when the naming of  typedef in C is an important keyword that is used to define a new name for existing types, it does not introduce a new type. The typedef is the compiler directive  4 Nov 2016 You can use typedef declarations to construct shorter or more meaningful names for types already defined by C or for types that you have  20 Jul 2020 Although it isn't really anything specifically associated with structs, typedef does tend to be used as a very common alternative way to define them. C - typedef - The C programming language provides a keyword called typedef, which you can use to give a type a new name.

Following is the general syntax for using typedef, Introduction to typedef in C typedef is a predefined keyword in C language. This typedef keyword tells the C compiler that “please assign a user given keyword to the already existing type”. It Means typedef gives an alternative user-friendly keyword for existing C language data types like unsigned int, long, int, char, float, etc. 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: 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 specifier, when used in a declaration, specifies that the declaration is a typedef declaration rather than a variable or function declaration.
