Typedef
RESERVED KEYWORD IN THE C AND C++ PROGRAMMING LANGUAGES
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.
