The IO.File.____________________ command opens a text file and assigns it to an object variable.​

As with other variables,an array declared as a class-level variable is visible to all procedures within the class.​

A(n)____ form allows users to switch to other forms within the application while it is open.​

Objects on a form cannot be referenced from any other form.​

A sequential search is the most efficient way of searching for an element.​

The BinarySearch procedure returns ____ if the desired value is found in the array.​

When an array is initialized but do not assign values immediately,no default values are automatically assigned to the elements.​

​ -​A form that is shown as ____________________ allows the user to switch to other forms in the application.

The array procedure ____________________ arranges the elements in an array from the smallest value to the largest.​

The elements in an integer type array will be initialized to ____.​

Identify the letter of the choice that best matches the phrase or definition​ a.​implicitly b.​zero c.​BinarySearch d.​upper-bound e.​parallel f.​function g.​two-dimensional h.​Sort i.​element j.​array REFERENCES: 530 530 530 531 532 532 542 543 545 546 -​An array with this kind of index declared is not implicitly sized

The ____________________ procedure of a Form object loads another form,hides the existing form and stops execution of code on the hidden form until this form is closed.​

When using the Preserve keyword to redimension an array to a smaller size,a separate array of elements will be made to store the values that were truncated from the end of the array.​

An application can only contain one Windows Form object.​

The ____ loop stops when the loop has processed every element in an array.​

When declaring an implicitly sized array,declaring a(n)upper-bound index will cause an error to occur._________________________​

An array with two index values for each element is a(n)____ array.​

When an array is declared,the numeric value specified in parentheses is the ____.​

Identify the letter of the choice that best matches the phrase or definition​ a.​implicitly b.​zero c.​BinarySearch d.​upper-bound e.​parallel f.​function g.​two-dimensional h.​Sort i.​element j.​array REFERENCES: 530 530 530 531 532 532 542 543 545 546 -​When this procedure is applied to an array,the lowest value is placed in the first element

The ____________________ object is used to write lines of text to a file.​
