      public:
              void innerFunction();
      };

}; void OuterClass::outerFunction() {

 cout << "This is a function in the base class\n";
 InnerClass myclass;
 myclass.innerFunction();

} void OuterClass::InnerClass::innerFunction() {

  cout << "This is a function in the InnerClass class \n";

} int main() {

 OuterClass myclass;
 myclass.outerFunction();

 return 0;
