Using template functions is an example of ___________ abstraction.

When you define a class as a template,then that class can contain _________ data type.

Which of the following describes a class that would be a good candidate for conversion to a template class?

When would you want to make a function a function template?

Classes can be defined as templates.

Templates are an example of algorithm abstraction

Writing a template class

If your program defines a class template,then the compiler will generate a class for each different data type for which it is instantiated.

Which of the following is a correct template prefix?

All classes should be converted to templates

In a template function definition,all parameters must be of the template class T).

Given the following template function definition,which of the following is not a valid invocation of the function? Template <class T> Void swapT& left,T& right) { //implementation goes here,not relevant to the question } Int int1,int2; Float flt1,flt2; Char ch1,ch2; String s1,s2;

Which would be the correct way to instantiate a containerClass object in your main program? Template <class T> Class containerClass { Public: ContainerClass); ContainerClassint newMaxSize); ContainerClassconst containerClass& source); ~containerClass); T getItem); Int getCount); Int getSize); Void addItemT item); Private: T *container; Int maxSize,count; };

If you want to make a function a template function,you must precede the function declaration and definition with

Given the following function template,which of the following are NOT valid calls to larger? Template <class T> T largerconst T& left,const T& right) { Ifleft > right) Return left; Else Return right; }

Using templates in your program where warranted,is an example of

In a class template implementation,every use of the class name as the name of the class should be followed by <T>.

If you need to pass a class template named myClass)function an object of the class as a value parameter,then the type of the parameter is

In the following function template,what must be true in order to use the function with a given data type? Template <class T> Int smallest T array[],int size) { Int small=0,i; Fori=0;i<size;i++) { Ifarray[i] < array[small]) Small=i; } Return small; }

If you define some list class template in your program,and then declare a list of integers,2 lists of doubles and 1 list of strings,how many different version of the template class will the compiler provide?
