It looks to me that you are reading data into a buffer that does not get deleted at the end. Check your code for the ever so elusive buffer.

One way to do this, which is easiest on the user, is to extract the numeric content of the entry and go on. Here is a simple code snippet: [php]// A foolproof input routine for numbers: // The input string is analyzed for nondigit characters // which are removed, the …

I used to play around with Borland BGI graphic stuff more than twenty years ago, and am amazed that this thing still hangs around. When Windoze first came out, I learned to use the Graphics User Interface (GUI) and a bunch of API calls to do graphics. I am quite …

I hope this is not homework! That would be cheating! This will do something like that, learn from it: [php] #include <iostream> #include <iomanip> // for setw() #include <stdlib.h> // for system() using namespace std; int main() { int k; int scores[50]; // array to hold 50 integers // initialize …

Attached is an HTML file (zipped) that has all the information about disks you ever wanted.

Since you are writing a C program use getchar() to wait. [code]// you can also use just #include <iostream> // this works in DevCpp because iostream chain-includes down // to sdtio.h (not recommended for portable code) #include <stdio.h> int main() { printf("Hello, world!\n"); getchar(); // wait return 0; } [/code]

The getpid() function gets the (unique) process identification from the system. You need to include the process.h header. Beware, this function is not standard C. [code]#include <stdio.h> #include <process.h> int main() { printf("This program's process identification number (PID) " "number is %X\n", getpid()); printf("Note: under DOS it is the PSP …

There is a DOS based tile game with mouse support written in Turbo C++, check: [php] http://www.programmersheaven.com/d/click.aspx?ID=F26995 [/php]

How about this one? It's also in the C code snippets. I never knew it would work for anything below 1900, but it shows 01/01/1800 to be a Wednesday. [php]// function to return the day of the week given the date // Original Turbo C modified for Pelles C #include …

Try this, works well with the free Dev C++ compiler. [php]// display arrow characters with Dev C++ #include <iostream> using namespace std; int main() { char left,right,up,down; up = 24; down = 25; left = 27; right = 26; cout << up; cout << down; cout << left; cout << …

You will not be adding up your total with something like =+ the correct operator is += Unless you have to use double return key, I would go with something as simple as t1 and flag down the 't' character to exit the loop.

This site has an example of eyes folowing the cursor. The program is for Visual C++ and is surprisingly simple.

There is enough English there to find your way around. It also gives …

The VB6 Working Model is floating around for almost free on a CD ROM with a number of books. I picked up "Sams Teach Yourself Visual Basic 6 in 24 Hours" at Borders for $19.99. The VB6 Working Model performs well, but lacks the help files. At least you get …

Just Extreme's code a little tidied up for Dev C++ Hope you can see the flow of things. [code]// Dev C++ code #include <iostream> using namespace std; int main() { int k, m; for(k = 1; k <= 10; k++) { // outputs 1,2,3,...,10 stars for(m = 0; m < …

You might want to look into Visual C++ Express. The beta version of this "student edition" is still free at: [url]http://lab.msdn.microsoft.com/express/visualc/[/url]

Take a beginner's look at: [url]http://gd.tuwien.ac.at/languages/c/programming-bbrown/cstart.htm[/url] The best way to get the hang of it is to write a few programs. There is also a great free C compiler at: [url]http://smorgasbordet.com/pellesc/index.htm[/url]

Take a look at: [url]http://gd.tuwien.ac.at/languages/c/programming-bbrown/cstart.htm[/url] At this point, don't waste your money on poorly written and mostly outdated books.

You can look under Line and Curve Functions in the Win32 Programmer's Reference.

The "undetermined character constant" was just one error. I fiddled with the code a little, take a look: [php]// student's grades Dev C++ #include <iostream> #include <ctype.h> // toupper() using namespace std; class student { private: char st_name[25]; char st_major[25]; int i_test1; int i_test2; int i_test3; int i_average; char ch_grade; …

I found this neat little GUI calculator program on the net. It uses a function called _gcvt(double val,int limit,string cBuf), which seems to be used to convert a double val to a string cBuf, with some formatting and limiting. I replaced it with sprintf(), but the output looks rather crude …

There is one site I like (black on white): [url]http://gd.tuwien.ac.at/languages/c/programming-bbrown/cstart.htm[/url] and just for reference and comparison of C vs C++ look at: [url]http://www.cppreference.com/[/url] Don't worry, most C++ compilers handle C just fine.

Here is a little Delphi code that gives you just a hint: [code]// get the hard drive serial number (Delphi Pascal) procedure TForm1.SerialNumberButtonClick(Sender: TObject); var VolumeSerialNumber : DWORD; MaximumComponentLength : DWORD; FileSystemFlags : DWORD; SerialNumber : string; begin GetVolumeInformation('c:', nil, 0, @VolumeSerialNumber, MaximumComponentLength, FileSystemFlags, nil, 0); SerialNumber := IntToHex(HiWord(VolumeSerialNumber), 4) …

For a very detailed look at ListBoxes go to: [url]http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/listboxes/listboxes.asp[/url] Otherwise you have to write a little function to pad the string with spaces on the left.

Alfred E. Newman comes to mind with Mickey Mouse as vicemouse. Honestly, it doesn't matter, all these folks live in a different world! Dani would at least care about the younger folks.

There is a C code snippet in this forum under "Day of week given a date" that can give you an idea.

Just a hint! Mixing up l and 1 are easy to do and hard to catch reading the code. I would use slightly more meaningful variable names like q and r. Also avoid using the often used i in loops and counters, it is another hard to read character, replace …

double fmod(double x, double y) is a function, so you have to rewrite your code a little. It returns the remainder of the division x / y. Make sure to #include <math.h>

Breaking out of a loop does not necessarily mean the use of the break statement. The way you wrote the while loop does it for you. [php]// exit a loop (Dev-C++) #include <iostream> using namespace std; int main(int argc, char *argv[]) { char answer; while((answer != 'Q') && (answer != …

[QUOTE=N3wbi3C0d3r]I tried to do something similar but much more simple, but i dont know what i did wrong. Wont compile it right. [CODE] //Clock for seconds #include <iostream.h> int main () { int HH; int MM; int SS; int result; cout << "Enter Hours :HH:"; cout << " "; cin …

Wow, variables and types are a mess here! Narue is right, the compiler will bitch! Oops, where did the structure type come from? Eric, doing this thing in small stages might help! Like your input section, comment out the other code, Compile and test each stage!

Man, this gets my rusty brain working. exp(1/3*(ln(x))) gives you the cuberoot of x ln(x) can be found to the nth degree of accuracy via binary expansion and exp() via continued fraction expansion. This is a hint, go at it tiger!

This one is still looking for a name! Warning from the Department of Energy: There's a new computer virus on the loose that's worse than anything we've seen before! It gets in through the power line, riding on the powerline 60 Hz subcarrier. It works by changing the serial port …
