C# Programming videos | C# Part 5 - Variables and Data Types
Posted by Andrew Gould on 31 October 2014
This part of the Basic Programming in Visual C# series explains how to use variables - an integral part of any programming language. You'll learn how to declare a variable and choose its data type, how to assign values to and read from a variable and how to initialise a variable. You'll learn about working with different data types such as strings, numbers and dates and understand the importance of type-casting and converting data types.

Making a video bigger
You can increase the size of your video to make it fill the screen like this:
Play your video (the icons shown won't appear until you do), then click on the full screen icon which appears as shown at its bottom right-hand corner.
When you've finished viewing a video in full screen mode, just press the Esc key to return to normal view.
Improving the quality of a video
To improve the quality of a video, first click on the Settings icon:
Make sure you're playing your video so that the icons shown appear, then click on this gear icon at the bottom right-hand corner.
Choose to change the video quality:
Click on Quality as shown to bring up the submenu.
The higher the number you choose, the better will be your video quality (but the slower the connection speed):
Don't choose the HD option unless you have a fast enough connection speed to support it!
Is your Wise Owl speaking too slowly (or too quickly)? You can also use the Settings menu above to change your playback speed.
I noticed if the user enters a max age that is smaller than the min age, the message box returns a meaningless answer.
A) How can the code be amended to correct this?
B) Probably better if there's some data validation to prevent users entering a max age < min age.
You could use an If statement to deal with this situation. If statements are covered in the next video which you can see here https://www.wiseowl.co.uk/c-sharp/videos/c-sharp-basics/if-statements/
I hope that helps!
