Replacing an integer value with a blank space

dusty (25)
If the number zero is acquired via ifstream, how can you replace it with a blank space? I've looked around the web and found related things but nothing that helps with my particular issue. I have tried to simply replace the zero with ' ' but it doesn't work and sends my iomanip settings haywire. Relevant part of the program is:

You can't put chars in an int. You could use int then convert it to char to have a space.

i created char blank = ' ', and for the else statement changed the code to this. Now all the zeros read as 32. Any ideas?

	q4cnt++;
}
else
	quiz4 = blank;

I just noticed in your first version shown you did not use " for cout. Try changing that or do this:

Don't set the int as a space with a char.
Example how to do it:

int tf = 0;
	if (quiz1 != 0)
{
        q1AVG += quiz1;
	q1cnt++;
}
else
	tf = 1;
if (quiz2 != 0)
{
	q2AVG += quiz2;
	q2cnt++;
}
else
	tf = 1;
if (quiz3 != 0)
{
	q3AVG += quiz3;
	q3cnt++;
}
else
	tf = 1;
if (quiz4 != 0)
{
	q4AVG += quiz4;
	q4cnt++;
}
else
	tf = 1;
}
if (tf == 1) cout << " ";


Never mind this I think I'm wrong.

Never mind that shouldn't be the problem. Tell me what it does when you run it.

This creates a space before the entire cout << right << setw... if there is a zero in the inFile
