Understanding a union

Understanding a union: C: Data Structures, Pointers, and File Systems
Understanding a union: C: Data Structures, Pointers, and File Systems

A union works like a structure with a similar declaration, members, and reference to the members. The difference between a union and structure is that the union's members all share the same data space. Unlike a structure, you can set and access only one member of a union at a time. The union's shared data space makes its implementation risky as it's possible to corrupt the shared storage space unintentionally.
