First, don't "Run" but "Debug" your tool.
Then, in PB, you'll want to use the Standard I/O tab, not the Console
tab.
In Xcode, chose Show Stdio from the Debug menu.
Without getting to technical now, the Run window (only) shows the so
called stderr output stream.
This one is often used to printout error messages (hence the name...).
But if you're doing printf's, these will go to stdout and scanf will
take it's input from stdin.
The Console tab in PB when debugging is actually a GDB (debugger)
console, so not what you want (you'd use that to control the debugger).
The Standard I/O tab is "simulating" a terminal, so that's what you
want. That one is showing stdout (and stderr) and what you're typing in
will be stdin for your program.
hope that helps

Dear list,
This is a newbie question, so bear with me:
Question: Why do my C programs using scanf run perfectly in Terminal
but
not in the project builder run window?
More details: I write C programs in project builder using the
standard
tool. When the program includes the scanf function, I do not get the
desired
prompt in the run window of project builder. However, I do get the
desired
prompt when I run the program (which I build in project builder) in
Terminal.
Thank you.
