The function retrieveAt of the class arrayListType is written as a void function. Rewrite this function so that it is written as a value returning function, returning the required item. If the location of the item to be returned is out of range, use the assert function to terminate the program. Also, write a program to test your function. Use the class unorderedArrayListType to test your function.

int retrieveAt(int location, array){

   // Function to retrieve the element from the list at the position

   // specified by the location

   if (location <= array.size() - 1){

       return array[location];

   } else{

       cout<<"Location out of range";

       assert(); // Assuming the assert function is defined in the program.

   }

}

Explanation:

The void retrieveAt function is converted to a return function that returns the integer item of the array given the location and the array variable as arguments. The assert function is used to terminate the program.

the answer is d.
