Chapter 7.2, Problem 7.8CP

Program Plan Intro

Array:

An array is defined as a group that consists of similar data types, but the size of array can also declared which indicates that the number of values an array can hold and it is always indexed, starting from 0.

Declaration of an array variable:

• • An array variable is declared with “[]” after the data type.
• • The following is the syntax for declaring an array variable.

dataType[] arrayVar;

   or

dataType arrayVar[];

• • Both the above given statements can be used, but the former one is mostly used.
• • The element type can be any data type and the same data type must be used by all the elements.

Array initialization:

Array declaration does not initialize the array in memory location. So, we can assign the values to that particular array.

The sequence of values within the braces and separated with commas is referred as an initialization list.

The array can be initialized in initialization list by group of array element is given below:

const int size= 3;

int[] arrayVar = new int[size]{1, 2, 3};

The array can be initialized without size declaratory in initialization list is given below:

 int[] arrayVar = new int[]{1, 2, 3};

The array can be initialized without new operator in initialization is given below:

 int[] arrayVar = {1, 2, 3};
