you can certainly password-protect files -- and even entire directories.... the easiest way is called "setting permissions" on *nix and windows has an equivalent, and the password protection is your account login. of course if you share an account the issue is moot. you also have no protection against the …

you can probably do it with scanf() in a complex and obscure and difficult-to-understand manner. i don't know how. but i do know how to do it with fgets() and atoi() in a simple, straightforward and easily-understood maner..

dude, this is really freakin easy. 360 degrees in a circle. 60 minutes in a circle 6 degrees per minute 1 degree per 10 seconds 0.1 degree per second. you can have 10 second resolution and only use integers. if you need 1 second resolution, you're still only in tenths …

we're not going to fix your code for you dude. you're going to do that yourself. (1) keep track of each number pair you generate by setting the appropriate element in a 10x10 array. (2) each time you generate a new pair, check and see if your 10x10 array has …

[QUOTE=idlackage;1197176]The number I'm looking for is valid when it's positive, and nine digits.

for one thing, you're finding a minimum value so call the variable "min" or something. not "max" remember how when you found max, you started at the lowest possible value and worked up. you set[iCODE] max = 0[/iCODE] and changed it any time the current value was found to be …

well, you don't have a return value. but i dont know if that's the source of your error code. i don't use Dev C++ so I can't say. I use CodeBlocks (w/ MinGW on windows) or gcc (on linux). I do recommend CodeBlocks, because it's my preference. I've heard criticisms …

i think a peer review is absolutely necessary for tutorials. i mean, just look at the sad state of "code snippets"... there's some horrible, non-working stuff in there. if i didn't know this site, and i came across some of those snippets, i would be inclined to think they were …

your variables.c file should NOT have a "main()" function. your variables.c file should have ONLY the implementation of the three functions prototyped in variables.h. the two files, variables.c and variables.h are a pair. the .h declares the prototypes, the .c defines the implementation. you may not be used to seeing …

dude, that's WAY too much code to look at. but it's nicely formatted and commented. so thanks for that. i'll try and give it a once over, but in the meantime, you should really learn to use fgets() inconjunction with strtol() to get your input. using scanf() [I]can [/I]do it …

Ctrl z is not a C function. IOW, the interpretation of ctrl-z is system dependent, and is not necessarily EOF. For example, on unix, ctrl-d is used as EOF. On systems where ctrl-z is used, it still doesn't always get interpreted as eof, as you have seen for microsoft OS, …

one problem is your function, palindrome, expects two integers to be passed into it. you've declared these integers in main as 'i' and 'k' but you don't assign any value to them before passing them into the call to palindrome. therefore, they will either be zero or some large value …

no it's not. it's terrible. it's ugly. and it's unportable. it wont even compile on a standard C compiler. i doubt it even works.

interesting question. i believe this is a proper LCG. At least i can't say that it isn't. I don't fully understand how, but it looks like he's using shifts to perform modulus operation.

this is probably the most interesting Community introductions thread i've seen yet.

here's a simple answer: a "hash function" takes a string of an arbitrary and probably variable length (called the [I]key[/I]) , and transforms it into a single integer (called the [I]hash value[/I]) which is a smaller, fixed width value. hash functions are widely used in cryptography and database management, for …
