My journey through 2017

My journey through 2017:

Passed my dream subject CSE in 4 years by keeping a decent CGPA, thesis, extra curriculur, research papers, hackathons, project fair, ACM contests, math olympiad without any fail/retake in undergraduate
Did 1.5 years research thesis based on ML
Took some undergraduate classes
Got the graduation convocation cap
Done TA ship successfully
Solved 250+ more ACM type algorithmic problems after graduation
Submitted data mining paper and rejected 2 times from IEEE
Found that there is no job in BD industry for CSE researchers all are developing jobs except teaching career.
Moved to PHP based platform
Some failed interview for Software Engineering position
Got job at April 1 as a software engineer for 3.5 years just after practicing 20 days laravel framework ; there condition was so strict though! :/
unfortunately missed it
Found the condition of PHP jobs in the BD job market though I loved it since my childhood 🙁
Switched to C#/.NET
Enrolled professional training outside of university curriculum for the first time through LICT+BCC scholarship
Got one semester temporary fulltime Lecturer position from an reputed university after passing 3-4 types of interview including written tests.
Seen everyone got the Lecturer job in FB page before Eid, I thought I am not selected and no chances, then I focused in C# training but one day got the call from HR unfortunately missed it for not understanding the HR tones of saying while I was sleeping after whole night coding the C# homework. Missed it 🙁
Attended BUET exam for the first time and failed :/
Got decent merit position in JU with 3 hr preparation for MSc
Got sick for the first time for jaundice
Attended some govt. job exam and found this is maybe not for me
published my technical blog with everyone in facebook after 7 years
My blog got hacked after 4 years
Recovered successfully in 10 minutes! :p
Learned about people, met with lots of positive and negative people, Learned some terms loyal,disloyal,fake from the real life
Searched someone special for myself
To be continued.
I am happy with my life and I have both failure and some success stories in 2017 which I didn’t share before. I am exploring my life. I am happy with it. Allah knows better where I am going in coming years. Please keep me in your prayers. 🙂

        public string StudentName
        {
            get { return sname;  }
            set { sname = value;  }
        }
    }

    class Program
    {
        static void Main(string[] args)
        {

            //obj.Display();
            Console.ReadKey();
        }
    }
}

using System;

obj.StudentID = 10;

obj.StudentName = "Zaki";

Console.WriteLine(obj.StudentName);

Console.WriteLine(obj.StudentID);

//obj.Display();

Console.ReadKey();

}

Automatic Property:

//auto implemented property

using System;

namespace LinqOperators
{
    class Student
    {
        public int Sid { private get; set; }
        public string Sname { get; set; }


       
    }

    class Program

}

Delegates:

using System;

namespace Delegates
{
    delegate int Caluclation(int Fnum, int Snum);

    class Delegates
    {
        public static int Add(int Firstnum, int Secondnum)
        {
            return Firstnum + Secondnum;
        }

        public static int Sub(int Firstnum, int Secondnum)
        {
            return Firstnum - Secondnum;
        }

        public static string Display(string Sname)
        {
            return Sname;
        }

        public static void Main(string[] args)
        {
            Caluclation calc = Add;
            Console.WriteLine(calc.Invoke(3, 4));
            calc = Sub;
            Console.WriteLine(calc.Invoke(10, 5));

            Console.ReadKey();
        }
    }
}

using System;

namespace Delegates

{

delegate int Caluclation(int Fnum, int Snum);

class Delegates

{

public static int Add(int Firstnum, int Secondnum)

{

return Firstnum + Secondnum;

}

public static int Sub(int Firstnum, int Secondnum)

{

return Firstnum - Secondnum;

}

public static string Display(string Sname)

{

return Sname;

}

public static void Main(string[] args)

{

Caluclation calc = Add;

Console.WriteLine(calc.Invoke(3, 4));

calc = Sub;

Console.WriteLine(calc.Invoke(10, 5));

Console.ReadKey();

}

Lambda Expression with FUNC:

using System;


namespace LamdawithDelegates
{
    delegate int MyDelegatesss(int firstNum, int secondNum);

    class Program
    {
        public static int Add(int firstNum, int secondNum)
        {
            return firstNum + secondNum;
        }
        static void Main(string[] args)
        {
            MyDelegatesss calc = Add;
            Console.WriteLine(calc.Invoke(5,4));
            Console.ReadKey();

        }
    }
}

using System;

namespace LamdawithDelegates

{

delegate int MyDelegatesss(int firstNum, int secondNum);

class Program

{

public static int Add(int firstNum, int secondNum)

{

return firstNum + secondNum;

}

static void Main(string[] args)

{

MyDelegatesss calc = Add;

Console.WriteLine(calc.Invoke(5,4));

Console.ReadKey();

}

Some logics:

//delegate example

delegate int MyDelegate(int firstNumber, int secondNumber);
MyDelegate myDelegate=(firstNumber,secondNumber)=>firstNumber+secondNumber
int result=myDelegate(3,4);
Console.WriteLine(result);

//delegate example

delegate int MyDelegate(int firstNumber, int secondNumber);

MyDelegate myDelegate=(firstNumber,secondNumber)=>firstNumber+secondNumber

int result=myDelegate(3,4);

Console.WriteLine(result);

Lambda using Function:

//lambda using FUNC
Func<int, int , int> funcdel=(a,b)=>{return a*b};
int Result=funcdel(30,20);
Console.WriteLine(Result);

//lambda using FUNC

Func<int, int , int> funcdel=(a,b)=>{return a*b};

int Result=funcdel(30,20);

Console.WriteLine(Result);

Multicast Delegates:

A delegate instance holding the multiple method at a time is multicast delegate.
But the rule is that all the method must be altered because all method in a single instance they remain present. Multiple reference method at a time.

using System;

namespace MulticastDelegates
{
    public delegate void MultiDelegate(int a, int b);

    public class SampleClass
    {
        public static void Add(int x, int y)
        {
            Console.WriteLine("Addition value:"+(x+y));

        }

        public static void Sub(int x, int y)
        {
            Console.WriteLine("Subtraction Value:"+(x-y)); 
        }

        public static void Mul(int x, int y)
        {
            Console.WriteLine("Mutiplication Value:"+(x*y));
        }

    }

    class Program
    {
        static void Main(string[] args)
        {
            MultiDelegate del = SampleClass.Add;
            del += SampleClass.Sub;
            del += SampleClass.Mul;
            del(10, 5);
            Console.WriteLine();
            del -= SampleClass.Mul;
            del -= SampleClass.Sub;
            del(10, 5);
            Console.ReadKey();
        }
    }
}

using System;

namespace MulticastDelegates

{

public delegate void MultiDelegate(int a, int b);

public class SampleClass

{

public static void Add(int x, int y)

{

Console.WriteLine("Addition value:"+(x+y));

}

public static void Sub(int x, int y)

{

Console.WriteLine("Subtraction Value:"+(x-y));

}

public static void Mul(int x, int y)

{

Console.WriteLine("Mutiplication Value:"+(x*y));

}

class Program

{

static void Main(string[] args)

{

MultiDelegate del = SampleClass.Add;

del += SampleClass.Sub;

del += SampleClass.Mul;

del(10, 5);

Console.WriteLine();

del -= SampleClass.Mul;

del -= SampleClass.Sub;

del(10, 5);

Console.ReadKey();

}

Anonymous Method:
Unnamed function. In the bracket we are writing the logic. Unnamed method we are writing the logic. Unanmed method.

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

namespace AnonynemousMethod
{
    public delegate double Areapointer(int r);
    class Program
    {
        static void Main(string[] args)
        {
            Areapointer point=new Areapointer(
                delegate(int r)
                {
                    return 3.14 * r * r;
                }
                );

            double area = point(20);

            Console.WriteLine(area);

            Console.ReadKey();
        }
    }
}

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace AnonynemousMethod

{

public delegate double Areapointer(int r);

class Program

{

static void Main(string[] args)

{

Areapointer point=new Areapointer(

delegate(int r)

{

return 3.14 * r * r;

}

);

double area = point(20);

Console.WriteLine(area);

Console.ReadKey();

}

The same AnonymousMethod work can be done in a single line with this lambda operation:

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

namespace AnonynemousMethod
{
    public delegate double Areapointer(int r);
    class Program
    {
        static void Main(string[] args)
        {
            Areapointer point = r => 3.14 * r * r;

            double area = point(20);

            Console.WriteLine(area);

            Console.ReadKey();
        }
    }
}

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace AnonynemousMethod

{

public delegate double Areapointer(int r);

class Program

{

static void Main(string[] args)

{

Areapointer point = r => 3.14 * r * r;

double area = point(20);

Console.WriteLine(area);

Console.ReadKey();

}

=> This is known as goes to operator and it is similar to AnonymousMethod()

Linq also using lambda not only Delegate

Func:

Func is a readymade function where the first data type is for input and the second one is for output. It does not need any delegate to declare.

using System;

namespace FuncwithLambda
{
    class Program
    {
        static void Main(string[] args)
        {
            Func<double, double> area = r => 3.14 * r * r;
            double result = area(20);
            Console.WriteLine(result);
            Console.ReadKey();
        }
    }
}

using System;

namespace FuncwithLambda

{

class Program

{

static void Main(string[] args)

{

Func<double, double> area = r => 3.14 * r * r;

double result = area(20);

Console.WriteLine(result);

Console.ReadKey();

}

Action:
Action does not support any return type:

using System;


namespace Action
{
    class Program
    {
        static void Main(string[] args)
        {
            Action<String> area = sttr => Console.WriteLine(sttr);
            area("zaki");

        }
    }
}

using System;

namespace Action

{

class Program

{

static void Main(string[] args)

{

Action<String> area = sttr => Console.WriteLine(sttr);

area("zaki");

}

DataReader and DataAdapter and DataSet

Difference Between DataReader and DataAdapter and DataSet:

Datareader: Datareader will be the best choice where we need to show the data to the user which requires no manipulation.

DataAdapter: DataAdapter read data from the database and is used to bind the data to the DataSet because DataAdapter working as a bridge between DataSet and the DataBase.

DataSet: DataSet is best suited where there is possibility of manipulation on the data.
