What is the reverse of cout.width? (C++)
Question
I was trying std::cout.width(int)
to see what it did, and it pushes the text right to fill a minimum width:
TH
becomes:
TH
to fill a minimum width of 10. I am wondering if A) there is a way to reverse this, have a number of spaces put AFTER the text to fill a minimum width, and B) is there a way to create a maximum width AND a minimum width?
And on a lesser note, is it possible to create a class derived from cout
or ostream
?
Solution
Width sets the "column" size for what you are printing next with cout.
std::cout << left << "Hello";
would print the above as "left" aligned in the column you made.
Different "types" are aligned to certain sides by default.

One question at a time is a good idea, but you can't derive from cout because it is an instance, not a class. For details of deriving a new output stream type, read this book.
