Displaying Contents of a file in columns

[Salchester]

I am currently writing a program, that outputs contents from a txt file. The only problem is i need the information to be presented in columns. How can this be done. Could i use ' if ' statements.

Many Thanks

considder this code

#include <stdio.h>
int main()
{
  int i;
  for(i=1; i< 21; ++i)
    if(i%3)
      printf("\t%d", i);
    else
      printf("\t%d\n", i);
  printf("\t%d\n", i);
  return 0;
}

Many Thanks,

Question, what does the % sign mean. Could you explain to be what the coding does, so that i can understand a bit more!!!!!

Many Thanks

the % is modula operator, it tells what the remainder of teh equivalent division would have been
7/3 = 2 and 1 remains
6/3 = 2 and 0 remains
7%3 = 1
6%3 = 0
So the if() clause will be true for as long as 3 dosn't add up to i.
So you'd just let the else clause hold the linebreak, this will only be printed for every third loop through the printout.

Is there anyway this can be achieved, just woundering.
Many Thanks
