Code:
/* C typedef assigns a name to a type. Its syntax can be really awful. */ #include <stdio.h>
/* Make fred an alias for the type name integer. */ typedef int fred;
/* Assign a type name to an enumeration. */ typedef enum { Sun, Mon, Tue, Wed, Thu, Fri, Sat} day;
int main() { fred m = 5; day today = Fri;
if(today == m) printf("Yes!\n"); else printf("Nope.\n"); }
The typedef is the only way to create type names in plain C. It essentially aliases for types for other types. It still exists in C++, but is not used very often, since classes are usually used to create new types.
