Templated Classes: (Declarations) Which of the following demonstrates proper syntax for defining a templated class? template class myArray { private: T *ptr; // this private pointer type is 'deferred' until compile-time int size: public: myArray( ints) ptr = new T[s]; // allocate an array of type T, of sizes size -s; // stores in private member "size" } }; myArrayai(5); // create an instance of myArray template class myArray { private: T*ptr; // this private pointer type is 'deferred' until compile-time int size: public: myArray( ints) ptr = new T[s]; // allocate an array of type T, of size 5 size -s; // store s in private member "size" } }; myArray-int> ai(5): / create an instance of myArray class myArray { private: T*ptr; // this private pointer type is 'deferred' until compile-time int size; public: myArray(Tarr[], int s) { ptr = new T[s]; // allocate an array of type T, of size s size -s; // stores in private member "size" } myArray-int> ai(5); // create an instance of myArray class myArray private: T*ptr; // this private pointer type is 'deferred' until compile-time int size; public: myArray(Tarr[], int s) { ptr = new T[s]; // allocate an array of type T, of size 5 size = 5; // store s in private member "size" } }; myArray int> ai(5); // create an instance of myArray
