[c++]Question about setw

[Banfa]

weaknessforcats am I doing something wrong in my code because I can't find anything about a stringstream only being capable of being used once.

You can reuse a stringstream, however in doing so you need to reset it first before you try to use it call the method

stringstream::c lear();

on your instance of the class before trying to reuse it.

Doesn`t `setw` set the width of the column to which the data is printed?; whereas \t sets the width of the column separating the 2 data columns.
e.g.
cout<<setw(3)<< i<<"\t"<<setw(5 )<<i*i<<"\n"; //might keep the data columns tidier.

\t does not set the width to anything, it is a character and how it is handled normally depends on the terminal to which you send it.

Commonly the terminal moves the output cursor to the next column multiple of 8.
