2. Explanation:

   To find:

   1) Why we need array?

   2) Is array replaces the concept of loop?

   3)Write the syntax of array declaration and initialization with an example.

   Solution:

   1) Array is a collection of similar data type.Whenever we have a requirement of taking input which are all similar we declare and initialize array.

   Note*: Array of alphabets is known as string.

   2) Yes, array replaces the concept of loop.

   3) Syntax of array declaration:

   syntax of array declaration is different in different programming languages.

   I hereby write syntax of C language:

   variable_type Name_of_array[size]

   for eg:

   INT BRAIN[5]

   here BRAIN is an array of integer type,it has one dimensional.

   In simple terms we can store 5 integer values in BRAIN.

   Syntax for array initialization:

   Variable_type Name_array[size]={integer values separated by commas}

   The array which declare above will be initialize like this

   INT BRAIN[5]={27,12,25,11,5}

   Note*: Array can be initialize while declaration:

   for eg:

   INT BRAIN[ ]={27,12,25,11,5}

   Hope it helps you.
