A structure contains an ordered group of data objects . Unlike the elements of an array, the data objects within a structure can have varied data types. Each data object in a structure is a member or field. A union is an object similar to a structure except that all of its members start at the same location in memory.

Union. 1. Definition. Structure is the container defined in C to store data variables of different type and also supports for the user defined variables storage . On other hand Union is also similar kind of container in C which can also holds the different type of variables along with the user defined variables.
