Thread: How to draw points?

The thing is that i've got to make a program for school to calculate distances between points and the shortest way and all that. But i would like to add a function to draw the points like a graphic and so. how can i do it? i don't have a clue because all we've done so far is dos-based programs

If you don't want to include libraries take a look at this faq . It shows you how to format output. Especially look here

Code:

#include <stdio.h> 

int main ( void )
{
  printf ( "%5d\n", 123 );      /* Prints "  123" */
  printf ( "%*d\n", 5, 123 );   /* Prints "  123" */
  printf ( "%+05d\n", 123 );    /* Prints "+0123" */
  printf ( "%x\n", 123U );      /* Prints "7b" */
  printf ( "%#x\n", 123U );     /* Prints "0x7b" */
  printf ( "%#X\n", 123U );     /* Prints "0X7B" */
  printf ( "%-10.2f\n", 12.3 ); /* Prints "12.30" */
  printf ( "%10.2f\n", 12.3 );  /* Prints "     12.30" */
  printf ( "%lu\n", 123UL );    /* Prints "123" */
  printf ( "%s\n", "Testing" ); /* Prints "Testing" */
  printf ( "%c\n", 'A' );       /* Prints "A" */

  return 0;
}

Then you could use --- and ||| for the streets/paths.

Yes, something like that, althoug it seem rather dificult. I haven't got many programming knowledge.
