To create the array variable named ar, you would use :

a. int ar;

b. int() ar;

c. int[] ar;

d. none of these

Option (c)

Explanation:

In java language this type of declaration is possible. Full declaration would be:

int[] ar=new int[n]; //where n is size of array to be passed.

But, this is not possible in c,c++. In java, int[] ar, int ar[] ,int *ar all are creating an array. Array is a data structure which stores elements of similar data type and in a contiguous memory. Array can be initialized at the time of declaration as well or it can be read from user with the help of for loop as well. In c,c++ array can be initialized by int arr[] or int *ar only .
