Search autocomplete function in emacs

I am looking for a plugin to create an autocomplete popup for developing C ++ in emacs. what I tried is Cedet Semantics and autocomplete mode , they are pretty neat in terms of completing variable and function names, if I already have a few words. For example, I have a class called foo and a function that returns the integer 1

class foo{
   int getInt(){return 1};
};

In the main method, while I started typing this

int main(){
 foo bar;
 bar.get...
}

plugins have no problems with the appearance of sentences like bar.getInt (). However, what I'm really looking for is similar to Eclipse, as soon as I click the dot, possible options can be created for me. Is this possible in Emacs? Thanks

P.S. CEDET ++?
