CSharp .Net Matrix Multiplication Program with Output

Posted by 20Fingers2Brains on Tags: , , ,

C# .Net Matrix Multiplication Program 

This C#.net program is about Matrix Multiplication with output and source code.For matrix multiplication we take 2D arrays and perform multiplication operations on two arrays and store the result in third array. Matrix multiplication program is compiled and executed using microsoft visual studio and .net compiler

Matrix multiplication program Logic:

  • First we declare two integer variable m and n to store the matrix dimensions entered by user
  • Declare three two dimensional arrays to store matrix A, matrix B and matrix C
  • Read matrix A using for loop and store it in array matrix a[m,n]
  • Read matrix B using for loop and store it in array matrix b[m,n]
  • Perform sum of matrix A and matrix B   using for loop and store it in array matrix c[m,n].
  • using  c[i, j] += a[i, k] * b[k, j];
  • show content of matrix a , 
  • show content of matrix b and 
  • show content matrix c as multiplication of matrix a and matrix b

csharp dotnet break keyword example

Posted by 20Fingers2Brains on Tags: , , , ,

C# .net Program Break Keyword Example

  • This C# .net Program is about use Break Keyword.
  • Break Keyword is used to break the flow of program and throw the control outside the loop or conditional statement.
  • Break keyword will bring the control out of current loop in which it is written not out of all the loops.
  • Break Keyword in c# can be used with
  • For Loop
  • Swith Case
  • While Loop
  • Do While Loop
  • If Condition
  • If Else Condition

C# Program Logic:

  • In below c# program we have used while loop to show use of break keyword
  • The initial condition of while loop is set to true
  • The integer variable num is initially set to zero and incremented by 1 inside the while loop
  • Inside the while loop we have used if condition to check when the break statement should be executed.
  • In this program when the num variable is equals to 5 then the break statement is executed and controls comes out of while loop

Break Keyword C# Program

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

namespace BreakProgram
{
    class Program
    {
        static void Main()
        {
            int num = 0;
            while (true)
            {
                //Increment the number by 1
                num++;
                Console.WriteLine(num);
                //if num is 5 , break the loop
                if (num == 5)
                {
                    Console.WriteLine("Break Statement Executed.");
                    break;
                }
            }
            Console.WriteLine("Program End.");
            Console.ReadLine();
        }

    }
}

Output of Break Program

Break Statement Executed.
Program End.

c# program convert array list to array example

C# Program to convert ArrayList to Array Example

  • This csharp program is about how to convert array list to array
  • In this c# Program first we have created ArrayList Object and named it as arrayList
  • In order to use ArrayList in our program we have to import System.Collections namespace.
  • After creating arrayList we have added items to the arrayList Object using arrayList.Add() method.
  • To store arrayList items to an array we have created an string array object.
  • Finally using  arrayList.ToArray(typeof(string)) as string[]; we have converted Arraylist to an array.
  • Following is the program to convert ArrayList to Array
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;

namespace ArrayListToArrayProgram
{
    class Program
    {
        static void Main(string[] args)
        {
            ArrayList arrayList = new ArrayList();
            arrayList.Add("AAAAAAAA");
            arrayList.Add("BBBBBBBB");
            arrayList.Add("CCCCCCCC");
            arrayList.Add("DDDDDDDD");

            string[] array = arrayList.ToArray(typeof(string)) as string[];

            Console.WriteLine("Contents of Array are:");
            foreach (var item in array)
            {
                Console.WriteLine(item);
            }
        }
    }
}


Output of Arraylist to array program.

Contents of Array are:
AAAAAAAA
BBBBBBBB

csharp program to find n prime numbers in c# dotnet

Posted by 20Fingers2Brains on Tags: , , , ,

Prime number program in csharp: c# program for prime number

  • The following code code prints prime numbers using csharp .net programming language. 
  • Logic for Primer Number is shown below in the code snippet with output: 
  • A number is prime if it is divisible only by one and itself. 
  • Number two is the only even and also the smallest prime number. 
  • Some example prime numbers are 2, 3, 5, 7, 11, 13, 17....etc. 
  • Every student learning programming in csharp .net will definately have to write the basic program to find prime numbers as it helps to develop the logical mind needed for programming
  • The following program will ask you to enter a number 
  • After taking the input number it will display the number of prime numbers
  • if you enter 10 the program will show the first 10 prime numbers
Prime Number Code:
 
 using System;

 namespace primerNumber
{
    class Program
    {
        static void Main(string[] args)
        {
            int num, i = 3, count, c;

            Console.WriteLine("Enter the number of prime numbers you want");
            num =Convert.ToInt32( Console.ReadLine());

            if (num >= 1)
            {
               
                Console.WriteLine("First "+num+" Prime Numbers are :\n");
                Console.WriteLine("2");
            }

            for (count = 2; count <= num; )
            {
