Deleting the last one

[Leon]

Hey, I would like to is there any way for deleting last item in output?
For example;
for(i=0;i<10;i++)
{
cout<<i<<" ";
}
I want delete last whitespace in output. How I can do that?

Why dont you just delete that one from the code?

Otherwise, you can use \b //backspace character// on the next line when you wanna delete that white space

[Leon]

But \b doesn't work..
when i wrote
cout<<"d";
cout<<"\b";
It doesn't delete the 'D' character in output.
????

Can you explain why you would wanna do that in the first place?

for(i=0;i<10;i++)
{
cout<<i<< (i==9 ? "" : " ");
}

The part of code which is problem for me
for(j=0;j<10;j++)
{
if(b[j]==1)
{
cout<<j<<" ";
}
}
Array 'b' has ten element each controlling one statement to be true (if the 1st statement is true b[0]=1)
the values of 'j' is the numbers I need, but there must not be a whitespace after last one.

@Leon
Try this..

for(j=0;j<10;j++)
{
   if(b[j]==1)
      { cout<<j;
        if(j<8)
           cout << " "; }
 }

This won't work, because depending on statements the last printed value of 'j' can be ,for example '6', it means again whitespace will be printed.((((

@Leon..
Sorry, I made a small error in the example. Here it is corrected !

for(j=0;j<10;j++)
{
    cout << b[j];
        if (j < 9) // Have j to equal 1 less than maximum value of j in for loop
           cout << " "; // whitespace ONLY printed upto, but not including, last j in for loop
 }

Hope this is better...

Moschops's code works, you know. It's got my vote. +1 to Moschops.
