Spacing Sample #1:
-------------------------------------
int main( void ) 
	{
	int x = 0;

	if( x < 0 )        /*  If X is Negative  */
		printf("Less than 0");
	else if( x == 0 )  /*  If X is Zero  */
		printf("Equal to 0");
	else               /*  If X is Positive  */
		printf("Bigger than 0");

	return 0;
	}

NOTES:
1.  These comments are on the same line as the conditional test
2.  Decide whether this is better than the next one
3.  I've got all the comments lined up with one another.



-------------------------------------
Spacing Sample #2:
-------------------------------------
int main( void ){
/* Variable: X -- indicates a positive, negative or zero value */
    int x = 0;

/*  If X is Negative  */
    if( x < 0 )        
	printf("Less than 0");

/*  If X is Zero  */
    else if( x == 0 )  
	printf("Equal to 0");

/*  If X is Positive  */
    else               
	printf("Bigger than 0");

/*  Ending Program  */
    return 0;
}

NOTES:
1.  These comments are all on their own line
2.  Decide whether this is better than the previous one
3.  I've got the comments aligned with the same context-level
    as the statement to which they apply.  See the page on
    Style.




-------------------------------------
Spacing Sample #4:
-------------------------------------
int main( void )
{
	int x = -5;

    /*  While Loop: Executes while X != 8.           */
    /*  Each execution of the loop increments x by 1 */
	while( x != 8 ){

		if( x < 0 )        /*  If X is Negative  */
			printf("Less than 0");
		else if( x == 0 )  /*  If X is Zero  */
			printf("Equal to 0");
		else               /*  If X is Positive  */
			printf("Bigger than 0");

		x++;              /*  Incrementing x by 1  */
	}

	return 0;
}


NOTES:
1. There's a blank line between the variable declarations and the
   while statements.
2. There's another one between the conditionals INSIDE the while
   statement and the x increment line.
3. There's another one between the closing brace for the while
   and the return statement.
4. Comments are on the same line as the applicable statement.

1.  Comments are on their own lines
2.  Sections of main are indicated by large comments.
