    copied!<p>I got a bit of issue here.</p> <ul> <li>Vehicle is parent class</li> <li>Car and Motorcycle is child class</li> </ul> <p>this is my main cpp file</p> <pre><code>int main() { // assuming max size is up to 100 VehicleTwoD *vehicletwod[100]; int vehicleCounter = 0; Car *car = new Car(); Motorcycle *motor = new Motorcycle(); cout &lt;&lt; " Please enter name of vehicle "; cin &gt;&gt; vehicleName; if (vehicleName == "Car") { vehicletwod[vehicleCounter] = car; //issue here vehicletwod[vehicleCounter].setName(vehicleName); //issue end } return 0; } </code></pre> <p>This is my car.cpp</p> <pre><code>struct Point { int x, y; }; class Car: public Vehicle { private: Point wPoint[4]; double area; double perimter; public: void setType(string); void setPoint(); string getType(); string getPoint(); } </code></pre> <p>The issue here is setName is a function of Vehicle, but not a function of Car. but i did the inheritance which should inherit the function. but doesn't seems to work.</p> <p>It say...Request for setName in vehicletwod[vehicleCounter]' which is of non class type VehicleTwoD*</p> <p><strong>Above Issue is fixed</strong> </p> <p>Additional Issue:</p> <p>Okay i fixed the previous issue by changing . to -></p> <p>Here the other issue.</p> <p>as the code is. on this part</p> <pre><code> if (vehicleName == "Car") { vehicletwod[vehicleCounter] = car; vehicletwod[vehicleCounter]-&gt;setName(vehicleName); //now i want to setPoint which is a function of child class vehicletwod[vehicleCounter]-&gt;setPoint(); //issue here } </code></pre> <p>I try to setPoint which is a function of child class, Car</p> <p>However it say.. Vehicle has no member named 'setPoint'</p> <p><strong>After doing what John mention.. the above issue is also fixed..</strong></p> <p>But the hardest part is on how to retrieve what been set since it is a vehicletwod object and not a car object.</p> <p>Assume after setPoint, i want to getPoint() </p> <p>i try do this</p> <p>vehicletwod[0]->getPoint();</p> <p>I get an error saying getPoint is of non-class type 'vehicletwod'</p>
