Did you post the EXACT question and code because that code will not compile due to several syntax errors. >>What will be printed if the user enters “Wingding”? Nothing because there is nothing in the program to accept anything from the keyboard.

The can of Dr Pepper I am now drinking doesn't emit any vibrations on its own, so that theory is proved false.

you can't do that. But what you can do is have a vector of vectors, just like a 2d array of doubles [code] vector<double> columns; vector<columns> rows; [/code] Now each row is like your vector_0, vector_1, etc.

I have no idea what you are talking about. What is "lazy evaluation" ? And why does it matter whether cio_putstr() returns void or something else ?

>>it sorts but then just quits out of the program for no reason.. Nope. It quits because there are problems with the code you wrote. Please post the code so that we can help you. The basic idea of sorting structures is the same as sorting an array of integers. …

you have a few problems with that class. I just put all the files into one *.cpp file because I was too lazy to use separate files as you posted them. The main problem was in the readBinary() function. Using the sample data you posted I got the same output …

Welcome to DaniWeb. With all your experience I suspect you will be a big asset for helping others.

>>Is it possible to print anything on screen in C or C++ without using main(). Yes -- write a MS-Windows win32 api program which uses WinMain() instead of main(). Or use VC++ 2008 and it will generate a console program that starts with _tmain().

I think your loop is wrong [code] int main() { char op; do{ printf("\n"); printf(" A : Quadrado\n "); printf("B : Rectangulo \n"); printf(" C : Circulo\n"); printf(" D : Triangulo\n"); printf(" E : Trapezio\n"); printf(" Indique a opcao : "); scanf("%c",&op); op = toupper(op); // cin.ignore(256); // printf(" Opcao …

read them in as characters so that you can read them one character at a time.

Is there a question there? Or are you just posting your code because you are very proud of it?

Too bad they don't [URL="http://www.youtube.com/watch?v=lF4qii8S3gw&NR=1"]teach this [/URL]in school any more :)

try pre-declaring the classes in the header files, but that works only if the object you want to use is a pointer. So you would probably have to change [icode]GLCursor MovementCursors [/icode]to a pointer [icode]GLCursor* MovementCursors;[/icode] [edit]what ^^^ said :) [/edit]

srand() doesn't return a value. All that function does is seed the random number generator. What you want is rand(), not srand(). srand() should be called only once at the beginning of the program to seed the generator. From then on the program calls rand() to get a random number. …

>>only prob i have now is storing it in2 an class array What array? You need to post the exact class declaration instead of making us guess what you are doing.

The first thing you have to do is design the structure. What information is on each line of the file? You can't do anything else until you figure that out.

Reading the information from the data file is very much similar to how you have it coded now to get it from the keyboard. The only difference is that you have to open an ifstream object. [code] ifstream in("infile.txt"); int i = 0; while( in >> studentInfo[i][0] ) { in …

Nice, but don't walk around their lawn in bare feet :) If you have ever stepped on a wet pasture pattie with bare feet then you know what I mean.

Why did you put all that C code inside a C++ program? I realize C++ supports FILE* and associated functions, but if you want to write c++ then do it the right way using fstreams and other c++ classes.

To find both row and column, start the function out by setting both values to 0, and [b]temp[/b] to the value of whatever is in a[0][0]. Then if the value in a[i][j] > temp (note: not >=) change the value of all three variables -- temp, row, and col.

>>unsigned short int If you are compiling for UNICODE you should be using wchar_t datatype for portability. *nix computers define wchar_t as unsigned long int, which is obviously not the same as MS-Windows. And the last time I read the UNICODE standard was considering a 64-bit integer so that it …

>>Is there an easy/fast way to convert C++ with class structure, etc to C? No. First convert the class to a structure and remove all its methods as well as access rights (public, protected, private). If it has base class(s) you will have to remove them too. Next, convert class …

compiling on a 64-bit operating system is not sufficient -- you have to build it with a 64-bit compiler.

Please seee post #11 in [URL="http://www.daniweb.com/forums/thread193067.html"]this thread[/URL] because its the same problem.

because no memory has been allocated to aSome -- its nothing more than a pointer that has a random address.

What operating system (and version) are you using? You may have to go to Tools --> Compiler Options --> Directories also in Programs tab, then add the full path to all files and programs

Great! start typing :) And welcome to DaniWeb.

All of the problems with the code you posted are due to carelessness -- misspelled words. When programming you have to learn to pay attention to small details, such as capitalization and spelling. Look at your compilers error messages and fix the problems one at a time. Normally the first …

who or what is libJudy? (don't tell me its a library because I already guessed that :) )

You really need to fix the problem instead of trying to hid it.Try commenting out large blocks of code until the program no longer produces those errors. That will narrow down your search for the problem.
