What is Class?

As we know, in any school system there are many classes and in each classes students belongs to many casts. So, Class is a group of different data types that casts. Class is also works like data type; just its calling terminology is different than all other data types. Integer (int), Character (char), Floating Point (float) is system defined data types but Class is user defined data type.

What are differences between sizeof operator and strlen function?

sizeof is keyword of c which can find size of a string constant including null character but strlen is function which has been defined in a header file named string.h and can find number of characters in a string excluding null character. Most probably it is used to compare the size of string with some conditions.   Example:-   #include<string.h> void main(){     int a,b;     a=strlen("itorian");     b=sizeof("itorian");     printf("%d  %d",a,b);     getch(); }

Swap two variables without using third variable in C

There are many ways to do this:-   Solution: 1   void main(){     int x,y;     scanf("%d%d",&x,&y);     //swapping     x=x+y;     y=x-y;     x=x-y;     printf("%d %d",x,y); }   Solution: 2   void main(){     int x,y;     scanf("%d%d",&x,&y);     //swapping     x=x^y;     y=y^x;     x=x^y;     printf("%d %d",x,y); }

C Programming Garbage Collection examples

#include<stdio.h> #include<conio.h> main() { printf("%d",printf("CQUESTIONBANK")); getch(); }   OUTPUT: Check the output on your compiler.   So, there are many garbage collection program in C and C++ programming language.   Try out one more program :-   main() { short int a=5; printf("%d"+1,a); getch(); }   OUTPUT: On Terbo 6, 51, d, compiler error etc. and on developer only d will be printed. Try on your compiler.

Migrating database from ASP.NET Identity to ASP.NET Core Identity

Image
As you know ASP.NET Core Identity (table structure) is different from what we had earlier in ASP.NET Identity. Actually the identity system which we have today with .NET Core is very mature and continuously evolved be it ASP.NET Membership, ASP.NET Identity 1, ASP.NET Identity 2 and now ASP.NET Core Identity. Recently I had to migrate few application to ASP.NET Core and similar its identity database. Because the table schema is changed, i had to re-think and create migration script which I would like to share with you today. It is very simple and easy, just three step and I had everything ready: STEP 1 : Change name of existing tables STEP 2 : Create ASP.NET Core Identity tables STEP 3 : Migrate data from old tables (ASP.NET Identity) to new tables (ASP.NET Core Identity) Script:  https://gist.github.com/itorian/c699e8534b392a6c726ec66c48100072 You should also watch my video, where I demoed migration.

Lambda two tables and three tables inner join code samples

In this blog post you will learn inner join using lambda queries. There will be two samples, in first sample you will see how you can join two tables and in second sample you will see how you can extend even further to join three tables and so on. I will sample in-memory data, but the same implementation will work with IQueryable (lazy query) too. Here's the code snippet:- namespace ConsoleApp1 {     class Program     {         static void Main()         {             var table1 = new List<Table1>();             table1.Add( new Table1 { Id = 1, Name = "Name 1" , Address = "Address 1" });             table1.Add( new Table1 { Id = 2, Name = "Name 2" , Address = "Address 2" });             table1.Add( new Table1 { Id = 3, Name = "Name 3" , Address = "Address 3" });             table1.Add( new Table1 { Id = 4, Name = "Name 4" , Address = "Address 4" });
