Struct Extension This tells the preprocessor to pull in the entire contents of multiprocessing.h and put them into the output file at this position.. Youll notice two different forms for the #include statement. Python The arguments of this command are the same as the second and third argument of \class. Python allows the writer of a C extension module to define new types that can be manipulated from Python code, much like the built-in str and list types. Returning multiple values using an array (Works only when returned items are of same types): When an array is passed as an argument then its base address is passed to the function so whatever changes made to the copy of the array, it is changed in the original array.

A union is used for grouping different types of variables under a single name. Quelle est la diffrence entre class et struct ? The struct statement defines a new data type, with more than one member. | Structures and unions will give you the chance to store non-homogenous data types into a single collection. typedef in C. The typedef is a keyword used in C programming to provide some meaningful names to the already existing variable in the C program.
