will compile but not run

[jthacker70]

Hey.. I have a problem and I am not sure what is going on. Hope it isn’t a silly question, but right now I have Borland C++ version 6 and am running XP none of my programs will run. If I have a program compiled and run it, nothing happens. The program will compile fine. But nothing happens when I execute it. The hello world program will not display hello world. An output window does not even open. I have tried other compilers, C++ and C, and all of them give similar results. On some of the compilers the output screen will flash then disappear. I am completely lost on this topic. I need a compiler on my computer so I can write my programs for class.... ANY suggestions or help will be greatly appreciated.

Oh yea.. I tried to input a value (cin>>x and it does not work either..

Do i understood you right: You has a "ordinary" C-compiler, not the Builder version?

And Your .EXE-file don't do anything when double-clicked?

Try to create a file with at specific name which does not crashes anything (something like "Testing.XXX") and close it. If this file creates....well, it runs!

Streams....isn't that a visual-thing???? I've never been friends with them....

Try x=GetChar() in stead, that's "good old-fasioned DOS"!

Keep making it perfect and it will end up broken.

Totte:

Streams are Standard C++, not a Visual C++ extension.

GetChar(), on the other hand, is non-Standard, and thus not guaranteed to be supported in every library implementation.


jthacher70:

Have you tried running the executables from on the command line?

That is, go to "Run Command" from the Start menu, type [tt]cmd[/tt], then use [tt]cd[/tt] (change directory) to navigate to where the executable is located, then type its name at the command prompt.

OK, i meant 'getchar()' which, according to "C: A reference manual" (ISBN 0-13-109802-0) is ANSI C standart and equals 'getc(stdin)' and is defined in "stdio.h".

By that the streams are already defined as ANSI C by the (stdin) so, Yes, the streams are standart C (ANSI).

Ok, yes, getchar all lower-case is Standard. Sorry for the misunderstanding.

There are also two types of Standard streams: the C FILE* streams (like stdin and stdout), and the C++ iostreams (like cin and cout, used by the original poster).
