 C Structure

A structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized

The structure is a user-defined data type in C language which allows us to combine data of different types together. structure assists with developing a perplexing information type which is increasingly significant. It is to some degree like an Array, however, a cluster holds information of comparable kind as it were. Be that as it may, the structure then again can store information of any sort, which is down to earth progressively valuable.

How to characterize structures? 

Before you can make structure factors, you have to characterize its information type. To characterize a struct, the struct watchword is utilized.

Syntax of struct

struct structureName

{

    dataType member1;

    datatype  member2;

     ...

};

Example

struct Person

{

    char name[50];

    int  no;

    float Salary;

};

Here, a derived type  Struct Person is defined. Now, you can create variables of this type
