hello frnds this is a snippet that removes comments of c, c++ , java files

This snippet will allow you to separate or "explode" strings into vectors via a character separator or the visa versa. In which case you would take a vector and "implode" it into a string separated by a character. Also keep in mind that this requires the libboost libraries. This was …

Generates all primes till n terms. Not a wonder scripts which will generate till billions, but works pretty fine till few millions.

A simple solution that prints the first n values in the fibonacci series up to the limit of an unsigned long. The program takes either command line arguments or interactive input for n and has code in place to make the program more flexible, like printing to a file.

Gives different combinations(Permutations) of string in input

This filters out the letters and numbers in the parameters you give it.

Here are some functions I made for SDL abstraction:

a string which can be used ala std::string, preserves case, but comparisons are not case sensitive.

This would let you store different things of same type into one data structure, here its a list. A good and popular example would be file and folder hierarchical structure in your computer. Perhaps this is what this code demonstrates. The code has two classes [INLINECODE]File [/INLINECODE]and [INLINECODE]Directory[/INLINECODE](derived from File). …

This code will create for you an application. we are goig to use visual c++ for it open visual, c++. click file then New. in the New dialogue box click projects. click win32 application. give it a name eg my_project. and click finish. Then again click file. click files. the …

This snippet shows different types of csting liblary implementation.

An interactive program using std::cin, std::cout, while loop and switch which will take from user no. 0 to 9 and print the number in characters. (eg. if user inters 0 the program shall respond You Have Entered : ZERO) If any negative number is given program should terminate.

This snippet has a will convert Decimal number to Binary number.

This snippet has a will convert Decimal number to Octal number.

This program was inspired by my college math 1 class. It takes the values of a1, a2, b1, b2, c1, c2 and solves, displays the equation and shows the work. It also stops if the equation is dependant or inconsistent (Zero division) Cramer's Rule if a1x+b1y=c1 and a2x+b2y=c2 then x=((c1*b2)-(c2*b1))/((a1*b2)-(a2*b1)) …

This program solves the geometric problem, called the Convex Hull problem. Given a set of points, the objective is to find a region such that the line joining any two points lies within that region. Informally, it is the polygon of largest area that can be formed out of the …

This is a simple rock paper scissors game using random numbers.

this's daoremon's song code i hope you ever see doraemon's movie...

Evaluates an expression as a string using reverse polish notation.

This code snippet actually contains a few nifty things. There are two functions, hasVisited() and main(). hasVisited() makes use of a very handy function for CGI programmers: getenv. You can see I use it to retrieve REMOTE_ADDR which is the person's IP address. In main() it gets the count from …

here is code for reversing a string

This can be used for plotting radioactive decay of an unlimited* number of elements, decaying into each other. *Limited only by memory and user attention span.

For those of you who live at home, run this on your parents' computer fullscreen, blue background, white font. Then put the mouse over the block in the upper lefthand corner, and enjoy the show.:twisted:

This code will let you play Battleship against the computer (bad graphics, I know) for a while, upon which it quits without so much as an error message. Could an experienced coder look this over and tell me why? Thanks. Venomlash :?:

this small function calculate mCr

This is a little code for a shell that allows for simple redirection and multiple yes! MULTIPLE piping abilities. It is slightly glitched for background processes, and this is only my second program written with C/C++ so it looks to be quite inefficient, but the piping works pretty nicely. The …

I created a bowling game, Which for the most part works correctly. I toiled for hours trying to figure out how to do the scoring so i gave up. Its fairly simple code so not much of a description needed.

So you want random numbers with negative values... How do you get them? This is a simple method to do so.
