Visual C++ 6.0 Runtime Error

[=?iso-8859-1?q?Drag=F3nChristiano?=]

The following code doesn't appear to run correctly compiled with Visual
C++ 6.0. I haven't gotten a chance to try this in GCC yet. "A" is
never output, not even on the first iteration. I have heard of
something called a stacking error, could someone please explain this to
me?

while(infile>>c){
cout << "A";
while(flag){
cout << "B";
if(isalpha(c)){
total++;
} else {
flag=false;
}
}
words++;
flag=true;
}

I don't know what you mean by "stacking error", but please see the
following FAQ:

Your post falls under FAQ 5.8.

I don't know what that is, sorry.

Have you tried debugging (stepping through) your program?

while(infile>>c){
cout << "A";

Try adding a nudge:

cout << "A" << flush;

while(flag){

BTW, what's the value of 'flag' the first time around?

cout << "B";

Maybe even add 'flush' here too.

if(isalpha(c)){
total++;
} else {
flag=false;
}
}
words++;
flag=true;
}
