Question

What is generics in C

Answer 1

Basically, generic is used when you need to write a class or a function which can work with any kind of data types. You can define classes and functions with a place holder. You can use it something like this:

using System; 
// < > to specify Parameter type 
public class example <T> { 
// private data members 
private T data; 
// using properties 
public T value 
{ 
// using accessors 
get
{ 
return this.data; 
} 
set
{ 
this.data = value; 
} 
} 
} 
// Driver class 
class Test { 
// Main method 
static void Main(string[] args) 
{ 
// instance of string type 
example<string> name = new example1<string>(); 
name.value = "anything"; 
// instance of float type 
example<float> version = new example<float>(); 
version.value = 5.0F; 
Console.WriteLine(name.value); 
// display 5 
Console.WriteLine(version.value); 
} 
}
