Question

Thoroughly discuss and answer the following questions. Copy the questions to your submission and answer them underneath each question.

1.What is the difference between an array’s size declarator and a subscript?

2.What is “array bounds checking”? Does C++ perform it?

3.When an array name is passed to a function, what is actually being passed?

Answer 1

1)

Subscript is used to access array elements for example: arr[0]
Array size declarator is used to define the size of array at the time of decleration i.e the number of elements the array will hold.

2) C++ does not perform arrayBound Checking.
array bounds checking is a check that prevent the program to access beyond the bounds of array. This support is provided by some language but not C++

3) The Base Address of the array.
