Question

As of now I’m using below line to print with out dot’s

fprintf( stdout, '%-40s[%d]', tag, data); 

I’m expecting the output would be something like following,

 Number of cards..................................[500] Fixed prize amount [in whole dollars]............[10] Is this a high winner prize?.....................[yes] 

How to print out dash or dot using fprintf/printf?

Answer 1

A faster approach:

If the maximum amount of padding that you’ll ever need is known in advance (which is normally the case when you’re formatting a fixed-width table like the one you have), you can use a static ‘padder’ string and just grab a chunk out of it. This will be faster than calling printf or cout in a loop.

static const char padder[] = '......................'; // Many chars  size_t title_len = strlen(title); size_t pad_amount = sizeof(padder) - 1 - title_len;  printf(title); // Output title  if (pad_amount > 0) {     printf(padder + title_len); // Chop! }  printf('[%d]', data); 

You could even do it in one statement, with some leap of faith:

printf('%s%s[%d]', title, padder + strlen(title), data);
