What is a structure in C explain the syntax of structure declaration with example?

Syntax of struct struct structureName { dataType member1; dataType member2; … }; For example, struct Person { char name[50]; int citNo; float salary; }; Here, a derived type struct Person is defined. Now, you can create variables of this type.

Defining a structure. struct keyword is used to define a structure. struct defines a new data type which is a collection of primary and derived data types. Syntax: struct [structure_tag] { //member variable 1 //member variable 2 //member variable 3 …

A “structure declaration” names a type and specifies a sequence of variable values (called “members” or “fields” of the structure) that can have different types . An optional identifier, called a “tag,” gives the name of the structure type and can be used in subsequent references to the structure type.

Declaration. The general syntax for a struct declaration in C is: struct tag_name { type member1; type member2; /* declare as many members as desired, but the entire structure size must be known to the compiler.
