Answer:
Option (c)
Step-by-step 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 .
