To create a template class, you begin with _________ A. the template definition B. the keyword class C. the function definitions D. the keyword definition

The correct answer is: A. the template definition

A template class is a class that can be used to create multiple classes with different types. To create a template class, you begin with the template definition. The template definition is a special kind of function definition that specifies the type parameters for the template class.

The keyword class is used to define a class. The function definitions are the definitions of the member functions of the class. The keyword definition is not used in C++.

Here is an example of a template class definition:

c++
template <typename T>
class MyClass {
public:
void print() {
std::cout << "The type of the object is " << typeid(T).name() << std::endl;
}
};

This template class can be used to create classes with different types. For example, the following code creates a class called MyInt that is a specialization of MyClass for the type int:

c++
MyInt myInt;
myInt.print(); // prints "The type of the object is int"

The following code creates a class called MyString that is a specialization of MyClass for the type std::string:

c++
MyString myString;
myString.print(); // prints "The type of the object is std::string"
