[Solved]Problem with skipws I/O manipulator

[JoshuaS]

Hello everyone!

I'm a bit confused about how to use the skipws I/O manipulator.

Suppose I have the following code:

string [ ] = "   Message";
cout.setf ( ios::skipws )
cout << string;
cout.unsetf ( ios::skipws )

I would expect the output of this to be:

Message

But instead it is:

   
   Message

So what am I doing wrong? I've searched wih Google, but I can't find anything that points me in the right direction.

Thank you in advance.

When the skipws format flag is set, as many whitespace characters as necessary are read and discarded from the stream until a non-whitespace character is found before every extraction operation.

That means skipws is for input.

It also doesn't work for input here. If I try to use the following code:

#include <iostream>
#include <fstream>

using namespace std;

int main ( )
{

    char string [ 100 ];
    ifstream infile ( "test" );

    infile >> skipws;
    infile.getline ( string, sizeof ( string ) );
    cout << string << '\n';

    return ( 0 );

}

Which will fetch the line " Hello" from the file test, my output is still:

             Hello

and not
Hello

Does anybody know what is going wrong?

Thanks in advance!

I've figured it out: you need to use the "ws" I/O manipulator, and not the "skipws" I/O manipulator!
