C structures are defined by some special and large variables of various data types.

It is contained by several named variables that is represented in a single name. Any program structure is usually consists of some logical expression with a predefined organized way. The 'C Structure' must be composed in the following specific arrangement:

• Documentation section
• Link section
• Definition section
• Global declaration section
• Main ( ) function section
• Subprogram section

For an example, if we want to create a C Structure, we will use 'strut' keyword. it is the compressed form of structured data type.

         struct struct name {

            DataType member1_name;

            DataType member2_name;

            DataType member3_name;

            …...............................................;

         };
