Compiler V4.140
I have tried fprintf(pc,"<%6s>", "a"); but it does not work.
| Code: |
I want it to print "< a>". But it prints "<a>".
|
How do i fix this?
Is it even possible in CCS?

Just put a space in the format string:
fprintf(pc,"< %5s>", "a");

The forum removed my extra spaces. |

If your string is only one character, then the same answer applies. Just put more spaces....
However it sounds as if what you want is to 'right justify'. If so, then you have to do this by filling.
So (for instance):
| Code: |
#include <string.h>
//arrive here with your string in a variable 'a'
char filler[7]=" "; //note 6 spaces
fprintf(pc,"<%s%s>",filler+strlen(a),a);
|
This prints 6-the_length_of_'a' spaces from 'filler', then the string 'a'.
Beware - if 'a' is longer than 6 characters....
