In this video, we will discuss and learn about how to use templates in C++ in Hindi.
C++ is a programming language that offers a lot of flexibility and power. It can be used to develop software in many different fields such as gaming, mobile apps, desktop applications, websites and more.
Templates in C++ are a powerful tool that can help you create reusable code without having to write the same code over and over again. Templates allow you to define the structure of your class or function, while leaving behind all the boilerplate code like function declarations and variable declarations for you to fill in later. This makes templates an ideal solution for creating reusable code.
Utilizing templates in C++ has numerous advantages, including:
It reduces duplication,
It reduces repetition, improves coding efficiency,
Maintains consistency throughout a programme,
Makes your code more readable.
The template in C++ is a programming language construct that allows you to create multiple instances of the same type of object with a different set of parameters.
When you want to create a template, you need to define the template and then declare that it is going to be instantiated with different types of parameters. The main difference between this and other languages is that in C++, we can provide more than one template definition in the same file. These definitions are differentiated by their name and their parameter types.
So, when we want to create a new type of object, we will use the following syntax:
template
T myObject;
myObject = new T();
Templates can be used in many different ways, but they are most widely used by C++ programmers to create efficient and reusable code. They allow a programmer to define functions or classes without having to specify the type of each argument individually.
The use of templates reduces the amount of code that needs to be written and provides more flexibility when it comes to changing the implementation later on.

A template is a programing code that contains the basic structure of a program. It has a set of instructions that are repeated in the code. For example, in C programming language, the following code is an example of a template:
#include
int main() {
printf("Hello World!");
return 0;
}
The above code prints "Hello World!" and returns 0 as the result.
A template is a programming language construct that allows the definition of one or more functions, called specializations, that can be used repeatedly to generate new objects. Templates are declared and instantiated with the help of a compiler.
A C++ template is a set of function definitions that can be used to create different types of objects at compile time. It is defined in terms of the type parameters and their corresponding arguments which are used to instantiate it during compilation time. Templates provide a mechanism for generic programming in C++, where the type and behavior of an object is determined by its template definition.
The main purpose of templates in C++ is to allow users to write generic code without having to know how many times they will use it. They provide a way for users to re-use existing code, and allow them to specify variables with one set of codes that must be used in all uses of the template. Templates also provide a way for users to make arguments optional so that the compiler can automatically decide how best to use the arguments based on type tye. Templates are declared with the keyword template followed by a list of parameters that are all separated by commas.
C++ templates provide a way to create reusable code. They are also used to define generic functions that can be used in multiple places in the program.
A template is a type of class that contains the definition of a function or data member and its interface. Templates are declared using the template keyword and they are instantiated using the new keyword. Templates are typically defined as an alias for other types, which can be specified in parentheses after the template name, or in angle brackets (like).
A C++ template is instantiated by providing an argument list for each of its parameters, which corresponds to each parameter's position in the parameter list for the template declaration. For example, if we have a declaration of a function that takes two integers as parameters and returns their sum ,int add(int x, int y) { return x + y; } then the following expression instantiates the function template:Example 1: Expression to instantiate a template having two parameters and returning their sum.double result = add(1, 2); // Instantiate with 1, 2 as argument list.
C++ is a programming language, which enables programmers to create software applications. It's often difficult for people who are new to programming to understand how C++ works, so it might seem like an intimidating concept.
The benefits of learning about templates in C++ in Hindi are:
- It will help you learn the basics of C++ without getting stuck on the syntax
- You'll be able to use templates in your own project
- You'll be able to use them with other languages as well
Templates can make the development process easier for programmers who want to reuse some parts of their code in different programs. They also help programmers save time by reducing the number of lines of code they have to write.
There are many benefits of using templates in C++:
- It helps reduce redundancy,
- It makes coding more efficient,
- It helps maintain consistency across a program,
- It makes your program more readable.
