Managed code is a code whose execution is managed by Common Language Runtime. It gets the managed code and compiles it into machine code. After that, the code is executed.The runtime here i.e. CLR provides automatic memory management, type safety, etc.Managed code is written in high-level languages run on top of .NET. This can be C#, F#, etc. A code compiled in any of this language with their compilers, a machine code is not generated. However, you will get the Intermediate Language code, compiled and executed by runtime.C/C++ code, called "unmanaged code” do not have that privilege. The program is ... Read More
For sorting the rows in a meaningful way we can use ORDER BY clause. Suppose we want to sort the rows of the following table −mysql> Select * from Student; +--------+--------+--------+ | Name | RollNo | Grade | +--------+--------+--------+ | Gaurav | 100 | B.tech | | Aarav | 150 | M.SC | | Aryan | 165 | M.tech | +--------+--------+--------+ 3 rows in set (0.00 sec)The query below sorted the table by ‘Name’.mysql> Select * from student order by name; +--------+--------+--------+ | Name | RollNo | Grade | +--------+--------+--------+ | Aarav | ...

Firstly, set the base −double n = 10;Now set the two exponents for division −double e1 = 10; double e2 = 8;Let us see the complete code to get the result of division of exponents of the same base.Example Live Demousing System; class Demo { static void Main() { double res, n, e1, e2; n = 10; e1 = 10; e2 = 8; res = e1 - e2; Console.WriteLine("Result = {0}^{1} : {2}", n, res, Math.Pow(n, res)); Console.ReadLine(); } }outputResult = 10^2 : 100
You can execute statements in C# in checked or unchecked context.In checked, the exception is raised by arithmetic overflow, whereas in unchecked context, arithmetic overflow is ignored.Checked ExceptionsUse the checked keyword to explicitly enable overflow checking for integral-type arithmetic operations and conversions. For this, just set the checked keyword.Overflow checking can be enabled by compiler options, environment configuration, or use of the checked keyword.res = checked(val + 10);Let’s say the value of val is 2147483647 i.e. the max value of int type. The above will raise an error since it is checked. This enables overflow checking at runtime.Unchecked ExceptionUse the ... Read More
Firstly, set the base.double n = 2;Now set the two exponents for division.double e1 = 5; double e2 = 4;Let us see the complete code to get the result of multiplication of exponents of the same base.Example Live Demousing System; class Demo { static void Main() { double res, n, e1, e2; n = 2; e1 = 5; e2 = 4; res = e1 + e2; Console.WriteLine("Result = {0}^{1} : {2}", n, res, Math.Pow(n, res)); Console.ReadLine(); } }OutputResult = 2^9 : 512
Dictionary is a collection of keys and values in C#. Dictionary is included in the System.Collection.Generics namespace. Dictionary is a generic type and returns an error if you try to find a key which is not there.List collection is a generic class and can store any data types to create a list.A list is a group of items −List myList = new List() { "Maths", "English", " Science" };Dictionary is a set of key-value pairs.Dictionary d = new Dictionary(); d.Add("squash", 1); d.Add("football", 2); d.Add("rugby", 3);Looping is easier and faster in a list and access element using index ...

As we know that DESCRIBE statement will provide the information/structure of the whole table. With the help of DESCRIBE statement along with table name and the column name, we can get the information about that column.SyntaxDESCRIBE table_name col_name;Example1mysql> Describe employee ID; +-------+---------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------+---------+------+-----+---------+----------------+ | ID | int(11) | NO | PRI | NULL | auto_increment | +-------+---------+------+-----+---------+----------------+ 1 row in set (0.11 sec)The query above will give the information about the column ‘ID’ of a table named ‘employee’.Example2mysql> Describe ...

An operating system is a construct that allows the user application programs to interact with the system hardware. Since the operating system is such a complex structure, it should be created with utmost care so it can be used and modified easily. An easy way to do this is to create the operating system in parts. Each of these parts should be well defined with clear inputs, outputs and functions.Simple StructureThere are many operating systems that have a rather simple structure. These started as small systems and rapidly expanded much further than their scope. A common example of this is ... Read More
If we have ALTER ROUTINE privileges then with the help of DROP FUNCTION statement, we can delete a MySQL stored function. Its syntax can be as follows −SyntaxDROP FUNCTION [IF EXISTS] function_nameHere function_name is the name of the function which we want to delete from our database.Examplemysql> DROP FUNCTION if exists Hello1; Query OK, 0 rows affected (0.70 sec)Now after deleting the function, check for the CREATE FUNCTION statement and we will get the error as follows −mysql> SHOW CREATE FUNCTION Hello1; ERROR 1305 (42000): Function Hello1 does not exist.
