What are 2 main differences betweenarrays andstructs?

The two main differences between arrays and structures are as following according to me :-

1. Array is collection of data elements of same data type while a structure is collection of variables of different data types.

2.Array is a primitive data type while structure is a user defined data type.

There are other differences also which are as following:-

1. The size of array is fixed while the size of structure is not fixed as structure can contain different variables of different data types.

2.array is declared as following :-

int array [100];

where 100 is the size of the array means it can store up to 100 integer values.

struct class{

int roll_number;

char *name;

int admission_no;

};

3.Traversing and searching in an array is easy and fast while it is difficult and slow in structures.
