Structure in C

Structure is grouping of variable under one name. Simple variable can be used to hold one piece of information at a time and arrays can be used to hold one element of the same data type. But structures can hold more than one element with different data types. Structure can contain integer, character, float, double arrays.

Syntax for structure definition:
struct strucure_name
{
             structure elements;
};

The keyword struct is used to define and declare structure.
