'Game Programming Tricks of the Trade' is a compilation of techniques from today's leading game programmers. Beginners will get started with invaluable tips, while intermediate game programmers can use these tricks to take their skills to the next level. Notepad is a utility program for Windows operating system. This utility software helps to code various programs that can even control the system workings through which you can perform many tricks in it. These tricks are very interesting and you can use these tricks to prank your friends. To leave a comment for the author, please follow the link and comment on their blog: RDataMining.
What general tips do you have for golfing(tips and tricks) in C?
1. Use bitwise XOR or - minus sign to check for inequality between integers:
if(a^b)instead ofif(a!=b)save 1 character.if(a-b)instead ofif(a!=b)also save 1 character.
2. Abuse main's argument list to declare one or more integer variables:
3. The comma operator can be used to execute multiple expressions in a single block while avoiding braces:
4. The ternary conditional operator ?: can often be used as a stand in for simple if-else statements at considerable savings:
5. #define macros whose expansion has unbalanced braces/parentheses:
6. Use *a instead of a[0] for accessing the first element of an array.
7. Combine assignment with function calls:

8. Initialize multiple variables together:
Instead of this:
Do this:
9. Collapse zero/nonzero values
When you have an integer value and you need to collapse it to either 1 or 0, you can use !! to do so easily. This is sometimes advantageous for other alternatives like ?:.

Take this situation:
You could instead do this:
Another example:
Could be rewritten as:
10. Avoid catastrophic function-argument type declarations
If you're declaring a function where all five arguments are ints, then life is good. you can simply write
But suppose d needs to be a char, or even an int*. Then you're screwed! If one parameter is preceded by a type, all of them must be:
But wait! There is a way around this disastrous explosion of useless characters. It goes like this:
This even saves on a standard main declaration if you need to use the command-line arguments:

There are more than 100 R tips at http://pj.freefaculty.org/R/Rtips.html, which provide quick examples to small challenges in everyday R programming, especially for users switching from other languages to R. There is also a .PDF version for it at http://pj.freefaculty.org/R/Rtips.pdf.
It presents short examples on:
– Data Input/Output
– Working with data frames: Recoding, selecting, aggregating
– Matrices and vector operations
– Applying functions, tapply, etc
– Graphing
– Common Statistical Chores
– Model Fitting (Regression-type things)
– Packages
– Misc. web resources
– R workspace
– Interface with the operating system
– Stupid R tricks: basics you can't live without
– Misc R usages I find interesting.
