I am just begninning C and I was wondering this:

Just like in QBASIC yuo can use the LOCATE y, x function. Is there a
way to do this in C?

Not portably. Some platforms provide non-standard extensions, for
example "conio" for Microsoft systems.

This is in the FAQ.

19.4: How can I clear the screen?
How can I print text in color?
How can I move the cursor to a specific x, y position?

A: Such things depend on the terminal type (or display) you're
using. You will have to use a library such as termcap,
terminfo, or curses, or some system-specific routines, to
perform these operations. On MS-DOS systems, two functions
to look for are clrscr() and gotoxy().

For clearing the screen, a halfway portable solution is to print
a form-feed character ('\f'), which will cause some displays to
clear. Even more portable (albeit even more gunky) might be to
print enough newlines to scroll everything away. As a last
resort, you could use system() (see question 19.27) to invoke
an operating system clear-screen command.

Since some of us haven't yet begun QBASIC, you may want to explain what
the LOCATE y, x QBASIC function is supposed to do. If it's about locating
a substring inside a string, strstr() does the job.

No. It moves the console cursor to row #y, column #x.

Example

I actually knew that, but I wanted to point out the ambiguity of the
question, *especially* considering the subject line.

Well you sure were subtle about it. You had me fooled into thinking you
didn't know it.

To me his point was clear as crystal. His BASIC skills were clearly
impossible to deduce from what he said, but clearly not the point.

Yes, he had me fooled too.

Now he has me fooled into thinking that he can't admit he was wrong;
possibly because that would be an egregious (but common) character
trait in someone who delights in correcting others.

There was a flaw in my original post, that was a good give away: my
advice made sense only for the LOCATE y$, x$ syntax! ;-)

But if you hadn't yet begun QBASIC, how would you know the syntax
that language uses to refer to string variables?? ;-)

I have no problems admitting my ignorance on most BASIC dialects, QBASIC
included. However, that ignorance is not complete...

It seems to be one of the very few features common to all BASIC dialects
and I have already demonstrated certain familiarity with some of them,
in past discussions with Joona ;-)
