     As you know different type of variables can be used for different purpose having different types of data-types. C supports such types of a constructed data type, which is called Structure.

Definition :

     A structure is heterogeneous collection of related fields. Here fields are called structure member or structure element. Every field has different type-specifier (data-type).

The definition of structure of opposite of array, because array is set of homogeneous elements. But the structure has deep relationship with array.



Structure Variables : The general syntax used to declare a structure and structure variables is written as below :
struct structure-tag
{
  date-type1 strcture element-1 or member-1;
  date-type2 strcture element-2 or member-2;
  date-type3 strcture element-3 or member-3;
  ......................................................;
  date-type n strcture element-n or member-n;
};
main()
{
  struct structure-tag v1,v2,..........vn;
  local declaration;
  executable statements;
}


Simple Structure Program :



Output is as :

Name=Bintu
City=Muktsar

Structure within Structure (Nested Structure):



Output is as :
Enter the Name and City
