Read moreWhat is structure and union explain with example?
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.

In other words, it is a structure that allows the same storage space to be used to store values of different data types at different times.
Read moreWhich is better to use union or struct?
If you want to use same memory location for two or more members, union is the best for that . Unions are similar to the structure. Union variables are created in same manner as structure variables.

You can access the members , the way you are trying( but the structures which are inside the union should have unique members) but you should make sure that while compiling the code gcc should know that you are trying like that, command : gcc -fms-extensions file_name.
