What is the difference between an array of structures and an array within a structure?

Answer 1

The main differences between an array and a structure are:

An Array is a collection of similar data items.An array is derived data type.It behave like a built in data type. An array can be increased or decreased.

A structure is a collection of dissimilar data items.It is a user defined data types.It must be declared and defined.A structure element can be added if necessary.

Answer 2

A structure has a fairly small amount of different data items, which may be of different types. The items are referred to by name - each data item has its own unique name. An array has several items (possibly thousands, or even millions of them), usually all of the same type. The items are usually referred to by number - but you may want to do some reading on "associative array", for a different type of array. In the associative array, items are referred to by a key, which may be of text type.

Answer 3

In the C Programming language, a structure may contain MULTIPLE DATA TYPES, also including arrays of those types, and the structure becomes a USER-DEFINED type. An array may contain a number of items all of the SAME TYPE, including user-defined types such as structures (see above).

Answer 4

struct A {/*...*/}; // a type A structure

A a[100]; // an array of 100 type A structures

struct B {

int a[5]; // an array of 5 integers within a type B structure

};

Answer 5

array is a collection of same data type and structure can be collection of same of different data type.
