printf("%5d" ,3) -> " 3"
printf("%-5d" ,3) -> "3 "
printf("%s" ,center(5,3));
-> " 3 "
where spaces() is:
char *center(int width,int value) {
static char returnbuffer[MSL];
char buffer[MSL];
if (width>returnbuffer) abort();
sprintf(buffer,"%d",value);
memset(returnbuffer,' ',MSL);
returnbuffer[(width-strlen(buffer))/2]=0;
strcat(returnbuffer,buffer);
returnbuffer[strlen(returnbuffer)]=' ';
returnbuffer[width]=0;
return returnbuffer;
}
this _should_ center it, haven't tried it.
