All above is NOT- again NOT NOT NOT NOT C++...


the c++ way is - are you all still with me (pay attention... NOW)?

string a; // that is right, here we declare a string and named it a
string b; // same as above

// give some values to a and b...like

a="why cannot I still write c++ code";
b="c++ code";

a.find_first_not_of(b);

That is what we call sleek C++ code in the UNITED STATES OF AMERICA!

Now, re-read it 100 times and admit that above posts are flawed,
erronous, completely bizzare and ultimately useless.
