basic c++ question

[Pinoyguy75]

So I know '/t' is to add a tab after a word, but I forgot how to adjust that value (8 i think) to make it bigger or smaller. Can anyone remind me how this is done?

[henke37]

Nope, not possible, c++ does not have any screen, so you can not control how a tab character will be interpreted.

Actually it should be '\t' and you can try to use printf in your advantage here

printf("%xs","something");

Substitute x with the value you want for the tab.

I don't know a lick of C++ and I still know you can use C functions in C++ code.

That must say alot about you, then.

Yeah, I know, I use C++ mostly for OOP and memory management (I'm too lazy to use malloc), so I know C a lot better than C++.
Anyway, like wonderful said, C code works in C++, so if a quick solution is available in C, why not use it?

It is perfectly logical to use C code in C++. C++ is just an extension of C, so in a way C code is C++ code but not vise versa.

That's *mostly* true but when dealing with C console output functions things tend to get funky. Things work just fine if you only use C++ iostreams or if you only use the C output functions, but as soon as you start mixing them things can get out of sync quickly. You can end up with a situation where you do a

printf("Hello");
cout << "world";
printf("/n");

and your output is "worldHello"

You can mix them, but you have to make sure you call fflush() and cout.flush() every time you switch back and forth. It can be a headache and it's generally better to pick one set of functions and stick with it.

To answer the original question, to do any kind of formatting in C++, you want to use the functions in the iomanip header. If you want to output 5 spaces, you would do this:

#include <iostream>
#include <iomanip>

[snip]

   cout << setw(5) << ' ';

If you want to display 20 asterisks, you would do this:

#include <iostream>
#include <iomanip>

[snip]

   cout << setfill('*") << setw(5) << ' ';

[jmbpiano]

Ugh....

That last example should have been

#include <iostream>
#include <iomanip>

[snip]

   cout << setfill('*") << setw(20) << '*';
