Question
Describe the syntax we use for a class template.
Expert Solution
Step 1
Class template:
A class template creates basic outline for a class. The members of that class use arguments of the type template argument. The syntax statement for class template declaration is as below:
Step 2
template <class template_name> class class_name {
class_namemember_name( template_nameargument_name)
};
Class template specialization is the instant of a function created by the compiler from the template for a specific set of arguments passed to the object. The syntax statements are specialized as in the example below:
- Consider a class template display with type parameter class_name called with double arguments.
- The compiler then detects a display object invocation in the code.
- Type parameter template_name is substituted by double throughout the definition.
- The class template specialization created is display< double> instead of template type display <template_name>.
