Thread: [Dev-C++] A newbie question

I am in class learning C. I am trying to do something, just goofing not
schoolwork, and I wanted to know if I can put a variable in my printf
format string. IE

printf("%variables%5f%3s");

I am trying to make it where I can put spaces into a line but at
differing lengths each time.

If I am misspeaking by asking in this forum, please forgive me. If this
is not a place to ask questions of a general type, could you please
direct me where to go.
                                    Thanks,
                                                Blalock

p/s if this is the place for such posts, I have a thousand more :)

No.

You can try  #define, #ifdef, #ifndef, e.t.c. in some way but if you want to
create spaces only you can try something like this:

int main()
{
int i=0, spaces=0;

/* spaces are defined somewhere in the code */

for (i=0; i<spaces; i++)
printf(" "); /* It inserts spaces in a line */

...

return 0;
}

It is the right place.

Ok post them. :)

Hello,
  I am trying to make it where I can put spaces into a line but at =
differing lengths each time.=20

If you're using C (as you've said), you could try something along these =
lines...

#include <stdio.h>

Hello,

Here.  Let's try it this way (I hate my mail client by times... sorry =
about the double post guys).

How about something along these lines for variable spacing.

printf("%sSomething else.", sVar);

where sVar is a variable number of spaces.  You should be able to fill a =
string (character array in this case) via something in the <string.h> =
(or <cstring.h> if your compiler is predominantly C++) library.

strcat and strlen might be of use.
