no matching function for call to

here's the code, when calling functionC, the error messge is
"no matching function for call to `sampleB::functionB (sampleA&)"

Code:

class sampleA
{
  public:
  
  sampleA(){}
  
  void functionA(){}
  
  private:

};

class sampleB
{
   public:
   
  sampleA object1;
  
  sampleB(){}
  
   int functionB (sampleA& in)
  {
    in.functionA();
  }
   
   private:
};

void functionC (sampleB in2)
{
  in2.functionB(in2.object1);
}

the code above looks fine, but when applying it into program, the error happens:
" no matching function for call to `ocean::getcoordinates (submarine &)' "

Code:

typedef struct target
{
        int x;
        char y;
        bool hit;
        target *next;
} Target;

target *newTarget()
{
       target *temp;
       temp = new(target);
       temp->hit = false;
       temp->next = NULL;
       return temp;
}

class submarine
{
      public:
             submarine()
             {
                        head = newTarget();
                        head->next = NULL;
             }

             void setsub(string subname, int subsize, int depth)
             {
                        name = subname;
                        size = subsize;
                        maxdepth = depth;
             }

             int getcoordinates()
             {
                        int temp;
                        char tempchar;
                        cout<<"Please enter the X coordinate. (1-10)\n";
                        cin>>temp;
                        while (!(temp >= 1 && temp <= 10))
                        {
                              cout<<"Inappropriate coordinate. Try again.\n";
                              cin>>temp;
                        }
                        head->x = temp;
            }


      private:
              target *head;
              int size, maxdepth;
              string name;
              bool destroyed;

};


class ocean
{
      public:
             ocean()
             {
                    sub.setsub("Stealth Spy Sub", 1, 100);
             }

             int getsubcoordinates (submarine& sub)
             {
                  sub.getcoordinates();
             }


             submarine sub;
      private:
              int score, ammo;


};


void setup(ocean& in, ocean& in2)
{

          in.getcoordinates(in.sub);
}

ocean doesn't have a memberfunction called getcoordinates.
it is called getsubcoordinates.

This one is easy. You don't have a getcoordinates(sub&) method for ocean objects, but you do have a getsubcoordinates(sub&) method.

EDIT: Kurt types faster than me.
