I need to make myfile with a .html extension can somebody tell me how or write me a code?

Answer 1

string name;
cout<<"What would you like new html file to be named?"<<endl;
getline(cin,name);
cout<<"Creating New Html File...Moment."<<endl;

name+=".html"; // the crucial ommision?

ofstream myfile (name);

Answer 2

You simply need to add .html to the end of the file name:

name.append(".html");

Answer 3

Do you want to take into account the possibility that the filename entered by the user already ends in ".html" ? In that case, you can get the suffix with name.substr(name.size()-5) - after you've checked that there are at least 6 characters in name, of course.
