In C, the typedef(keyword) allows the programmers to define the new data type name by using existing data types in C. The keyword typedef helps to increase

needed */ typedef unsigned char Byte; /* Integer is the type used to declare an array consisting of a single int */ typedef int Integer[1];   Thus the typedef allows a simpler syntax when dealing with function pointers. This becomes more apparent when function pointers are used in more complex  Normally we use the standard name of data type like int, unsigned int, char, struct etc. to represent the feature of variable and function in the program. typedef  The typedef declaration provides a way to create an alias that can be used common C idiom to avoid having to write "struct S" typedef struct {int a; int b;} S, * pS  In C, the typedef(keyword) allows the programmers to define the new data type name by using existing data types in C. The keyword typedef helps to increase  typedef is a keyword in the C programming languages. The purpose of typedef is to assign alternative names to existing types, most often those whose standard  typedef int aaa, bbb, ccc; typedef int ar[15], arr[9][6]; typedef char c, *cp, carr[100]; /* now declare some objects */ /* all ints */ aaa int1; bbb int2; ccc int3; ar yyy;  People often use typedef to improve the portability of code, to give aliases to structure or union types, or to create aliases for function (or function pointer) types . In  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  In C programming, we use the typedef declarations to create shorter and meaningful names for types already defined by C like int, float or char.

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 keyword Typedef is used to give a new symbolic name for the existing name. Typedef is type definitions make code more readable by giving application-specific names to types. In this example, we will create type definition with structures. typedef is a keyword used in C language to assign alternative names to existing datatypes.

The C programming language provides a keyword called typedef, which you can use to give a type a new name. 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..
