A Simple FeedForward Three Input Perceptron(Neural Network) using C#

Simple Perceptron with binary classifier using C#

The following code is a simple three input perceptron neural network with a binary classifier using c#.
This neural net was the most primitive invented by Rosenblatt in 1959.

Simple Arithmetic Calculator using C#

Simple Arithmetic calculator in C# using Switch case

The following is the code for creating a simple arithmetic calculator using switch case:

what is a switch case?

Switch case helps the programmer to provide multiple conditions when multiple options are required to be provided

.

Syntax:

switch(variablename)
{
case expression1:
statement;
break;
case expression2:
statement;
break;
.
.
.
default:
statement;
break;
}


The Program for simple arithmetic calculator is as follows:


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class maths
{
static void Main(string[] args)
{
// float datatype chosen for decimal calculation.
float a, b;
// character datatype chosen to provide option for-
// switch case.
char option;

Console.WriteLine("Enter the numbers to be calculated");
// first value to be provided by the programmer.
a = Convert.ToInt32(Console.ReadLine());
// second value to be provided by the programmer.
b = Convert.ToInt32(Console.ReadLine());

Console.WriteLine("Enter the option");
Console.WriteLine("Enter a to add");
Console.WriteLine("Enter b to subtract");
Console.WriteLine("Enter c to multiply");
Console.WriteLine("Enter d to Divide");
// option to be inserted by the programmer.
option = Convert.ToChar(Console.ReadLine());
// switch case
switch (option)
{
// various options of switchcase(a,b,c,d)
case 'a':
Console.WriteLine("the sum is{0}:", a + b);
break;
case 'b':
Console.WriteLine("the difference is{0}:", b - a);
break;
case 'c':
Console.WriteLine("the product is{0}:", a * b);
break;
case 'd':
Console.WriteLine("the divided output is {0}:", a / b);
break;
// default option.
default:
Console.WriteLine("invalid choice");
break;
}

}
}
}

Simple C# - Add Two Numbers and Print out its Sum

C# Code-Add Two Numbers and Print out its Sum

The following is the code using C# to Add two numbers and print out its Sum,
The code below consists of integer(int) data type with values specified.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class sum
{
static void Main(string[] args)
{
// defining the datatype int a and int b.

int a = 5;// datatype int a(integer) with value 5.

int b = 3;// similarly int b(integer) with value 3.

// now addition of a and b and printing out its sum.

Console.WriteLine("The Sum Is :{0}", a + b);

}
}
}

But if the programmer wishes to input values of his own or technical term userdefined values the code is as follows.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class sum
{
static void Main(string[] args)
{
int a, b;
Console.WriteLine(" Enter the values to be added");

// provide user defined inputs

a=Convert.ToInt32(Console.ReadLine());
b=Convert.ToInt32(Console.ReadLine());

// print out the sum
Console.WriteLine("The Sum Is :{0}", a + b);

}
}
}

similarly other mathematical operations can be performed ,eg: subtraction,multiplication etc.

A simple C# program for Beginners-Hello World

The Following program is for people who have just started learning C# .

C# program for Beginners-Hello World

1. To create your first application , Open Visual studio 2008 or Visual C# Express edition.
2. In Visual studio select C# from the Menu and select Console Application.
3. Next in solution explorer on the right hand corner(if not visible click on view from the menu bar at the top and select solution explorer)rightclick on the program.cs file and rename it to helloworld.cs(it will pop up a message ,just press enter/return key)
4. you ll see the name of the class changes to helloworld (highlited in lighter shade of blue color).

So..lets get started,Now type in the following code,

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class helloworld // name of the class
{
static void Main(string[] args)// main method with void return type
{
Console.WriteLine(" Hello World");// print out the statement on command prompt.
}
}
}


Now Press key F6 to Compile /build the code or use mouse to click on build from the menu bar at the top.

Now Press Key Ctrl+F5 to see the output or choose option Debug from menu bar and click on start without debugging option.

Thats it...you just created your very first application using C#.

Simple C# Code to Arrange arrays in Descending and Ascending Order.

// The Following Code arranges the Single-Dimensional Array in Descending Order.

C# Code to Arrange arrays in Descending and Ascending Order.


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class descend
{
static void Main(string[] args)
{
int[] num1 = new int[5] { 55,2,90,45,7};// Array Defined of 5 elements.
Array.Sort(num1); //Sorts the Array first.
Array.Reverse(num1);//Reverses the Array
foreach (int i in num1)// Loop applied for each element in the array
{
Console.WriteLine(i);// Output Is Displayed
}
}
}

// To Arrange the array in Ascending order the code is given below;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class Ascend
{
static void Main(string[] args)
{
int[] num1 = new int[5] { 55,2,90,45,7};
Array.Sort(num1);
foreach (int i in num1)
{
Console.WriteLine(i);
}
}
}
}


Its the same as the code for arranging arrays in descending order ...except "Array.Reverse()" has been excluded from the code

.

// hope this helps you all.
