using sscanf in a loop

[b rad311]

Hi, How can I advance the sscanf statement to read each word in the sentence? Right now my output is an endless loop of "This".

CString incoming_line="This is my example incoming line.";
CString string_out;
while (sscanf(incoming_line, "%s", string_out )==1)
{
cout<<string_out<<endl;
}

Thanks!

you could do something like this:

int offset = 0;
while (sscanf(incoming_line + offset, "%s", string_out )==1)
{
cout<

Chris, Thanks for your help. I'm getting the following error when I use your suggestion.

Error 2 error C2666: 'ATL::CStringT<BaseType,StringTraits>::operator +' : 3 overloads have similar conversions

Any ideas? Thanks,

You cannot use a CString object in this capacity.

Hi David, Should I use "const char*" instead?

oops. didn't see the CString there.

If you did, then how would scanf() be able to change its contents? Since you are using MFC, have a look at CStringT::Tokenize() or AfxExtractSubString().
