I just installed vista yesterday and i use bloodshed compiler. Im doing standard iostream coding right now and the window wont stay open.

For example:

A simple hello world program wont stay open and a return value of 0 wont help, i dont know what to do.

This has nothing to do with Vista. Include the <cstdlib> header and then append this line to your source.

system("PAUSE");

If you're concerned about portability, "system (PAUSE);" isn't. The perception that a window should remain open until it notices that the user has finished reading the screen is incorrect. It is one of the most commonly expressed "problems" on any forum. A previous answer from this forum:

Quote:

Programs run until they complete, then terminate. If you run your program from the command line, then the window belongs to command.exe. When your program completes, command.exe will put out another prompt in the same window. Your output will still be showing.

If you run your program in its own window (double-clicking its icon, say), then it will terminate and the window will close.

If the IDE (if you have one) provides the window, then IT will stay open, but if it spawns a window specifically for that execution, the window will close.

Note that the key word is "terminate". You may add an input statement to the end of your program so that it doesn't terminate until you provide it input. It'll sit there and wait for that, giving you plenty of time to look. You can use "cin.get ()."

You will need to clear the input before "cin.get ()" in case your user has pounded in some extraneous stuff. You can use cin.sync (), although there is some controversy regarding its standardized applicability to a basic_istream, or you may use cin.ignore (). See your documentation.
