Programming: What's new in Programming Techology?

Whats new in Programming Technology?

World changes in seconds, even worst Computer world changes in picoseconds.Battle over programming languages continues and new technologies are evolving seconds by seconds.

Well programming life is not easy. It gets worst when you have to switch between one programming languages to other programming language. I know if we know the syntax of one one programming languages then its not that hard to learn other one.Today I am going to share some new programming experience with Windows 8 machines.

Windows world has changed. Now individual can write program in any programming language, make amazing apps (application) for multiple platforms.

We are no more limited to any programming language. We can use whatever programming language we like. Can you imagine building apps with wed development languages like HTML5, CSS and JavaScript? Well its real.

Now we can use HTML5, CSS and JavaScript to build awesome commercial application without knowing other hardcore programming like Java, C++ or C#.

Windows8 app store lets user do upload web based application as well which are perfectly written in web technologies. With the less knowledge of Java and C++, one can create great application with just basic knowledge of HTML5.

If you hate Windows and like other Open source platforms like Linux/ BSD or other programming then you should be happy enough that you can use the same skills to write apps for Ubuntu phones and desktops.

We know that New Ubuntu phones are coming and lots of application are being released. Its perfect time for programmers to switch their PC to Linux and download QT creator and start making cool apps.

Unlike Windows8 and Ubuntu apps can work for both Ubuntu phones and desktop computers. Which is great. Got to download the right tools and program great apps and help this world be a great place for programmer and general users.

C# 2012: Print your name five times

Do you love programming in command line, Program written in Visual studio using c# can be debugged in command line without GUI. Here is simple program written in C# which prints your name five times: 




using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Class_Activity_Friday_5_DC
{
class Program {
static void Main(string[] args)
{
for (int z = 1; z <= 5; z++)
{
Console.WriteLine("John Doe"); //Write your name
     }
   }
  } 
 }

The program is written using for loop. If you have some experience in programming then you will definitely understand it. Do not forget to comment me if you have any questions.

C# 2012: Quadratic Equation

If you are taking college algebra and you think its too difficult to do calculation. One more condition, if you are good in programming like me then go ahead and paste this code in your visual studio and do the college assignment in few minutes.
 I wrote this crapy codes in my c# class, back 2012. I passed maths class with A, because I developed right tool at right time. I have not pasted the .designer.cs file codes. If you have some experience in programming then you will be able to figure out yourself. Any questions, then feel free to comment down. Chill the code !!

            double B = Convert.ToDouble(coeffX.Text);

            double C = Convert.ToDouble(consTant.Text);
           

            double E = -B - Math.Sqrt((Math.Pow(B,2) - 4*A*C));
            double F = -B + Math.Sqrt((Math.Pow(B,2) - 4*A*C));
          
         
            double G = 2 * A;

            double Xp =(E)/(G);
            double Xn = (F)/(G);

            positiveX.Text = Xp.ToString();
            negativeX.Text = Xn.ToString();

        }

Windows 8 App: using javascript and HTML5

 Building First Windows 8 application which i can write Hello World. This is default.js file codes which are all javascript code. If you want to learn more about windows 8 Application development then I recommend you to visit http://www.msdn.microsoft.com

C# 2012: Pseudocode

Pseudo-code, literally it means fake or false  code. Knowing to write pseudo-code is very important fact in the life of programming. It helps you to figure out the flaws about your program and enhance your idea as well.

Here is a sample of pseudo code which helps in calculating the quadratic equation in simple way:
We know famous equation (ax2 + bX+ c = 0)
First of all we have to ask user Enter the value for coefficient of X(square):
and enter the value for coefficient of X and finally value for constant. Then we store the value in some variable and execute the formula:

//Global Variables
decimal a=0;
decimal b = 0;
decimal c= 0;

{
a = Convert.Todecimal(textbox1.text);
b = Convert.Todecimal(textbox2.text);
c= Convert.ToDeciaml(textbox3.text);

}

//write the forumla
decimal result = (formula goes here//);
textbox4.text = result.ToString();
}

This is just an example of pseudo code which works in theory but never executes in practical. Note: in the formula, you need to use Math method and operators to execute further. I can help you to understand the logical flow of the program.

You can comment me if you want to get further free codes in C#. Thank you!

Python : Simple Program

Python is one of the most important procedural programming language. I learnt this in my second semester. This is one of the simple program I would like to share:

#Conditional statement in entering bar

print ("Welocome to Okmulgee Dance Bar! ")
y = input ("What is your name ?"))
number = 18)
gate= int(input ("Enter your age: ")))
if gate== number:)
print ("You are right aged," + y, "Welcome and have fun"))
elif gate< number:)
print("Grow up," + y ,"Still wait some more years to come back! "))
elif gate> number:)
print("Welcome! "+ y ,"What would you like to have?"))
)
if gate >= number:)
z = input ( "Enter your order: "))
print("Thank you for ordering,"+ z, "! Your order will be proceed in few seconds!"))
elif gate < number:)
print("Thank you for your try! Hope you will turn 18 soon!"))
input ("press"))

C# 2012: Gravitation Force Codes

Its time for you to try new challenges in C# programming language. C# is one of the most powerful object oriented language. Its is easy to learn and can be programmed very efficient programs very easily.
Here are the screenshots:
-->

Initial Program

Result after entering data

Here are the free code: I have written the code myself. So it will be hard for you to understand but you can email or contact me to ask any questions:

Use this code to put in any .cs file:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Gravitational_Force
{
    public partial class Form1 : Form
    {
        //Global Variable
        decimal M1;
        decimal M2;
        decimal r;
        decimal Force;

        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            M1 = Convert.ToDecimal(txtM1.Text);
            M2 = Convert.ToDecimal(txtM2.Text);
            r = Convert.ToDecimal(txtR.Text);

            double G = 6.6726 * Math.Pow(10, -11);
            decimal Gc = (decimal)G; //Converting double to decimla
            Force = (Gc* M1 * M2)/ r * r;

            label10.Text = "Force = " +Math.Round( Force,10) + "N";

            label5.Text = "F = G * M1 * M2 * / r* r ";
            label6.Text = " F = 6.6726* 10 ^-11 * " + M1 + "*" + M2;
            label8.Text =  r + " * " + r;
            label9.Text = "------------------";
            label7.Text = " F =  " +Math.Round(Force, 10) + " N";
        }
    }
}
