C unions allow data members which are mutually exclusive to share the same memory . This is quite important when memory is valuable, such as in embedded systems. Unions are mostly used in embedded programming where direct access to the memory is needed.
Read moreWhat is the union of a C?
A union is a special data type available in C that allows to store different data types in the same memory location . You can define a union with many members, but only one member can contain a value at any given time. Unions provide an efficient way of using the same memory location for multiple-purpose.

A typedef declaration creates a new name (an alias) for an existing type. It does not define a new type. An enum declaration defines a discrete type with named values . If you’re trying to learn C by asking one question at a time, that’s not a good approach.

C programlama dilinde , struct (yapı), bir bellek bloğunda tek bir ad altında fiziksel olarak gruplandırılmış değişkenler listesini tanımlayan ve farklı değişkenlere tek bir işaretçi (pointer) aracılığıyla erişilmesine izin veren bileşik bir veri türüdür.
