C# Program to Implement Arithmetic Operations using Delegates

This is a C# Program to implement arithmetic operations using delegates.

This C# Program Implements Arithmetic Operations using Delegates.

Here the delegate is a form of type-safe function pointer used by the .NET Framework. Delegates are often used to implement callbacks and event listeners. A delegate does not need to know anything about classes of methods it works with.

Here is source code of the C# Program to Implement Arithmetic Operations using Delegates. The C# program is successfully compiled and executed with Microsoft Visual Studio. The program output is also shown below.

        {
            num *= b;
            return num;

            NumberChanger n1 = new NumberChanger(AddNum);
            NumberChanger n2 = new NumberChanger(MultNum);
            n1(25);
            Console.WriteLine("Value of Num: {0}", getNum());
            n2(5);
            Console.WriteLine("Value of Num: {0}", getNum());
            Console.ReadKey();

This C# program is used to implement arithmetic operations using delegates. Here the delegate is a form of type-safe function pointer used by the .NET Framework. Delegates are often used to implement callbacks and event listeners. A delegate does not need to know anything about classes of methods it works with. Print the arithmetic operation values.
