What is a template class?
Definition. As per the standard definition, a template class in C++ is a class that allows the programmer to operate with generic data types. This allows the class to be used on many different data types as per the requirements without the need of being re-written for each type.
What are templates?
A template is a form, mold, or pattern used as a guide to making something. Here are some examples: A ruler is a template when used to draw a straight line. A document in which the standard opening and closing parts are already filled in is a template that you can copy and then fill in the variable parts.
What is a template class in OOP?
A template is a blueprint or formula for creating a generic class or a function. The library containers like iterators and algorithms are examples of generic programming and have been developed using template concept.
How the template class is different from the normal class * 1 point?
How the template class is different from the normal class? Explanation: Size of the object of template class varies depending on the type of template parameter passed to the class. Due to which each object occupies different memories on system hence saving extra memories.
What is template and its types?
Templates in c++ is defined as a blueprint or formula for creating a generic class or a function. To simply put, you can create a single function or single class to work with different data types using templates. C++ template is also known as generic functions or classes which is a very powerful feature in c++.
What is the use of a template?
A template is a document type that creates a copy of itself when you open it. For example, a business plan is a common document that is written in Word. Instead of creating the structure of the business plan from scratch, you can use a template with predefined page layout, fonts, margins, and styles.

What is class template example?
A class template can be declared without being defined by using an elaborated type specifier. For example: template class Key; This reserves the name as a class template name. All template declarations for a class template must have the same types and number of template arguments.
What is the need for class template?
A class template describes a set of related classes or data types that differ only by types, by integral values, by pointers or references to variables with global linkage, or by a combination thereof. Class templates are particularly useful in describing generic, but type-safe, data structures.
What does template function indicate?
What does this template function indicates? Explanation: As the return type of function is template T, therefore, the function is returning a general type. Now as the function is taking a template T as its argument which is a general type, therefore, it is accepting a single general type argument.
What is class template in C++ Mcq?
1) Template is a feature of C++ that allows us to write one code for different data types. 2) We can write one function that can be used for all data types including user defined types.
What is difference between template and template?
What is difference between template and template . For me both are generating the same result. There is no difference. typename and class are interchangeable in the declaration of a type template parameter. You do, however, have to use class (and not typename) when declaring a template template parameter:
What is the use of class template?
Class Templates Like function templates, class templates are useful when a class defines something that is independent of the data type. Can be useful for classes like LinkedList, BinaryTree, Stack, Queue, Array, etc.
What is the difference between a template and a generic class?
The basic difference in generics has implications for building applications that combine templates and generics. For example, suppose you have a template class that you want to create a generic wrapper for to expose that template to other languages as a generic.
What are some examples of templates in C++?
Examples of function templates are sort (), max (), min (), printArray (). Below is the program to implement Bubble Sort using templates in C++: Class Templates Like function templates, class templates are useful when a class defines something that is independent of the data type.
