Predict the output or error(s) for the following:

class base

{

        public:

            virtual void baseFun(){ cout<<"from base"<<endl;}

        };

class deri:public base

{

        public:

            void baseFun(){ cout<< "from derived"<<endl;}

        };

void SomeFunc(base *baseObj)

{

        baseObj->baseFun();

}

int main()

{

base baseObject;

SomeFunc(&baseObject);

deri deriObject;

SomeFunc(&deriObject);

}

Answer:

            from base

            from derived

};

class deri:public base

{

public:

void baseFun(){ cout<< "from derived"<<endl;}

};

void SomeFunc(base *baseObj)

{

baseObj->baseFun();

}

int main()

{

}

Answer:

from base

from base

Explanation:

Predict the output or error(s) for the following:

class base

{

        public:

        int bval;

        base(){ bval=0;}

        };

 

class deri:public base

{

        public:

        int dval;

        deri(){ dval=1;}

        };

void SomeFunc(base *arr,int size)

{

for(int i=0; i<size; i++,arr++)

        cout<<arr->bval;

cout<<endl;

}

 

int main()

{

base BaseArr[5];

SomeFunc(BaseArr,5);

deri DeriArr[5];

SomeFunc(DeriArr,5);

}
