String comparison in Visual Basic:
- The relational operators are used to compare strings. The result of relational operations is always a Boolean value.
- The relational operators and their meanings are given below,
Symbol | Meaning |
< | Less than |
<= | Less than or equal to |
> | Greater than |
>= | Greater than or equal to |
== | Equal to |
<> | Not equal to |
Is | Compare references. |
- While comparing two strings, the corresponding letters are compared. And the result will be true if all the comparisons are true.
Explanation of Solution
2. “AAA”> “AA”
The Unicode of every letters are given below,
- The decimal value of “A” is 65. So when comparing “A” and “A”, “A” is equal to “A”...
Explanation of Solution
3. “ABC123”< “abc123”
The Unicode of every letters are given below,
- The decimal value of “A” is 65 and of “a” is 97. So when comparing “A” and “a”, “A” is smaller than “a”.
- The decimal value of “B” is 66 and of “b” is 98...

This application manages a parking space for a configurable maximum number of vehicles. The designed application must handle the following functions: ● Each garage slot has a width and depth that describes the slot dimensions.● The garage consists of a configurable maximum number of slots with different dimensions. ● Each vehicle shall be identified by a model name, unique identification number, Model year and vehicle dimensions (width and length).● Park-in function that marks the arrival time of a vehicle if there is an available slot that matches vehicle dimensions.● The slot selection for vehicle park-in could be done using multiple algorithms:○ First Fit selection where the first slot with big enough dimension to host the vehicle will be selected○ Best Fit selection where the slot with the best dimension match should be used where the wasting area of the slot is minimized. ● Slot selection algorithms could be extended in the future version of the application.● Park-out function…

(y/n): n Specifications The formula for finding the greatest common divisor of two positive integers x and y must follow the Euclidean algorithm as follows: Subtract x from y repeatedly until y < x. Swap the values of x and y. Repeat steps 1 and 2 until x = 0. y is the greatest common divisor of the two numbers. You can use one loop for step 1 of the algorithm nested within a second loop for step 3. Assume that the user will enter valid integers for both numbers.
