Do you need your newlines simply removed from the strings? And what is "within fixed with fields"? — Alexander Pavlov

I think he means that it should be space filled if the data cannot take the entire field (space padded) so that the field is always the same length — Adrian

If you have 3 strings, a, b and c, you should be able to use something like this...

printf("a=%-20s b=%-20s c=%-20s", a, b, c);

This will left align your strings and they will be fixed at a width of 20 each.
