The size of the array shoeSize? double [] shoeSize = {8.5, 7, 12.5, 9.5, 9, 11.5, 6} is 6
Explanation:
- Arrays are zero-based : the seven elements of a 7-element array are numbered from 0 to 6. Hence, the size of the array is 6.
- An array is collection of items stored at memory locations. The main aim of an array is to store multiple items of same type together.
- An array is a collection of one or more values of the same type. Each value is called an element of the array.
- The location of an item in an array is known as array indexing.
- The first array index is 0 or 1 and indexes continue through the natural numbers.
- The upper bound of an array is generally language and possibly system specific.
- An array type is a data type that represents a collection of elements each selected by one or more identifying keys that can be computed at run time during program execution.

Stack is LIFO data structure (Last In First Out) where the last element entered in stack will be the last one to be out of stack. It has three operations: push() : used to insert an element in stack, pop() : used to delete an element from the stack, top() : used to return the top of the stack i.e. the newest member of the stack. All these operations will take place at the top.
<u>Explanation:</u>
Now, looking at the program, x and y are initialized the values of 2 and 3 respectively. The stack pushes 8 onto the stack making it the first member of the stack. Then the value of x which is 2 is pushed onto the stack. Next, (x+5) = (2+5) = 7 is pushed onto the stack.
Pop() is used to delete hence 7 is popped out from the stack. top() is assigned to y which is 2 in this case and again 2 is popped out from the stack. Now, (x+y) = (2+2) = 4 is pushed onto the stack. And the top() is assigned to x which is 4. 4 is again popped out from the stack. Hence the value of x is 4.
