Control instructions in C#

There is a Chinese Proverb "If you give a man a fish you feed him for a day. If  you teach a man to fish you feed him for a lifetime.". Let me teach you how to fish for the answer to questions such as this.

First, do you know how to use the debugger? Are you familiar with breakpoints? Are you familiar with the debugging commands Step Into, Step Over and Step Out? If not then try to find articles about that or ask here.

Next, break up the code into something such as:


Then put a breakpoint somewhere in there such as on the "t1 = i | j & 5;" line. Then debug. First use "Debug | Windows | Locals" to show the Locals window. You probably want to pin the window to keep it showing. Note that we cannot show the Locals debugging window unless we are debugging so you won't find it if you are not debugging. Then single-step (Step Over) each line and watch what happens to the data. Note that the data will be shown using a red font if the data has changed.

I hope you learn a lot using these techniques many times in the future.
