1. The document discusses various concepts in Java programming including data types, variables, operators, and decision making statements. It describes integer, floating point, character, and boolean data types.
2. It also covers variable declaration and scope, constants, arithmetic, relational, and logical operators. Decision making statements like if and switch statements are used for conditional branching in a program.
3. The document provides examples of declaring and assigning values to variables, using different types of operators to perform calculations and comparisons, and the syntax of if and switch statements.
C# is an object-oriented programming language that was developed by Microsoft. Some key points:
- It is based on C and C++ but aims to be simpler and safer with features like automatic memory management and type safety.
- Variables must be declared with a type and can be initialized when declared. Common data types include primitive types like int and string, as well as value types and reference types.
- It includes standard programming constructs like conditional statements, loops, operators, and functions.
- Comments begin with // for single-line and /* */ for multi-line. Keywords and identifiers have specific naming rules.
C# is an object-oriented programming language that was developed by Microsoft. Some key features of C# include its support for classes, interfaces, inheritance, exceptions, delegates, and events. C# code is compiled to an intermediate language called Microsoft Intermediate Language (MSIL) that is executed by the Common Language Runtime (CLR). This allows C# programs to run on any platform that supports CLR.
The document discusses various data types in VB.net including Boolean, integer, floating point numbers, strings, chars, and dates. It provides examples of declaring and using variables of each data type. It also briefly discusses operators in VB.net, listing arithmetic, comparison, logical/bitwise, and assignment operators and providing examples of each.
VBScript is a lightweight scripting language that can be used for both client-side and server-side programming. It is a light version of Visual Basic. VBScript supports variables, arrays, procedures, functions, conditional statements like If-Else and Select Case, and loops like For Each, Do While, and Do Until loops. Built-in functions provide date, time, and mathematical capabilities.
The document discusses the Common Type System (CTS) in .NET framework 4.5. It defines built-in data types that can be used, including value types that directly contain data and reference types that contain references to data stored in objects. The document also discusses declaring and initializing variables, converting data types, creating user-defined types like enums and structures, control statements like if/else and switch, methods including passing parameters, and overloading methods.
The document discusses different types of looping statements in VB.NET, including While, Do, For, and For Each loops. It provides examples and syntax for each type of loop. The key types of loops are:
- While loops repeat statements as long as a condition is true.
- Do loops execute statements first, then check a condition to repeat.
- For loops repeat a set number of times, specified by a start and end value.
- For Each loops iterate through each element of a collection, such as an array.
C# is an object-oriented programming language that is simple, modern and type-safe, derived from C and C++. It aims to combine the high productivity of Visual Basic with the power of C++. C# programs are typically written in .cs files and compiled to .exe files using the Visual Studio IDE and command line compiler. The language uses the .NET framework class library and supports value types that contain data and reference types that store references to objects.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
Need for Speed: Removing speed bumps from your Symfony projects ⚡️Łukasz Chruściel
No one wants their application to drag like a car stuck in the slow lane! Yet it’s all too common to encounter bumpy, pothole-filled solutions that slow the speed of any application. Symfony apps are not an exception.
In this talk, I will take you for a spin around the performance racetrack. We’ll explore common pitfalls - those hidden potholes on your application that can cause unexpected slowdowns. Learn how to spot these performance bumps early, and more importantly, how to navigate around them to keep your application running at top speed.
We will focus in particular on tuning your engine at the application level, making the right adjustments to ensure that your system responds like a well-oiled, high-performance race car.
Fundamentals of Programming and Language Processors
C# language basics (Visual Studio)
1. Page 1 of 8
The first line of the program using System; the using keyword is used to include the System namespace
in the program. A program generally has multiple using statements.
The next line has the namespace declaration. A namespace is a collection of classes. The “Hello World”
Application namespace contains the class Hello World.
The next line has a class declaration, the class Hello World contains the data and method definitions that
your program uses. Classes generally would contain more than one method. Methods define the behavior
of the class. However, the Hello World class has only one method Main.
The next line defines the Main method, which is the entry point for all C# programs. The Main method
states what the class will do when executed
The next line /*...*/ will be ignored by the compiler and it has been put to add additional comments in the
program.
The Main method specifies its behavior with the statement Console.WriteLine("Hello World");
WriteLine is a method of the Console class defined in the System namespace. This statement causes the
message "Hello, World!" to be displayed on the screen.
The last line Console.ReadKey(); is for the VS.NET Users. This makes the program wait for a key press
and it prevents the screen from running and closing quickly when the program is launched from Visual
Studio .NET.
Its worth to naote the following points:
C# is case sensitive.
All statements and expression must end with a semicolon (;).
The program execution starts at the main method.
Unlike Java, file name could be different from the class name.
C# Type Conversion Methods: C# provides the following built-in type conversion methods:

Accepting Values from User:
The Console class in the System namespace provides a function ReadLine() for accepting input from the user and store it into a
variable.
Arithmetic Operators:
Operator Description Example
+ Adds two operands A + B will give 30
- Subtracts second operand from the first A - B will give -10
* Multiplies both operands A * B will give 200
/ Divides numerator by de-numerator B / A will give 2
% Modulus Operator and remainder of after an integer division B % A will give 0
++ Increment operator increases integer value by one A++ will give 11
-- Decrement operator decreases integer value by one A-- will give 9
Relational Operators:
Operator Description Example
== Checks if the values of two operands are equal or not, if yes then condition becomes true.
(A == B)
is not
true.
!=
Checks if the values of two operands are equal or not, if values are not equal then condition
becomes true.
(A != B)
is true.
>
Checks if the value of left operand is greater than the value of right operand, if yes then
condition becomes true.
(A > B)
is not
true.
<
Checks if the value of left operand is less than the value of right operand, if yes then condition
becomes true.
(A < B)
is true.
>=
Checks if the value of left operand is greater than or equal to the value of right operand, if yes
then condition becomes true.
(A >= B)
is not
true.
<=
Checks if the value of left operand is less than or equal to the value of right operand, if yes
then condition becomes true.
(A <= B)
is true.
Logical Operators:
4. Page 4 of 8
Operator Description Example
&& Called Logical AND operator. If both the operands are non zero then condition becomes true.
(A && B)
is false.
||
Called Logical OR Operator. If any of the two operands is non zero then condition becomes
true.
(A || B)
is true.
!
Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is
true then Logical NOT operator will make false.
!(A &&
B) is
true.
Conditions:
Statement Description
if statement
An if statement consists of a boolean expression followed by one or more
statements.
if...else statement
An if statement can be followed by an optional else statement, which
executes when the boolean expression is false.
nested if statements
You can use one if or else if statement inside another if or else
if statement(s).
switch statement
A switch statement allows a variable to be tested for equality against a list of
values.
nested switch statements You can use one switch statement inside another switchstatement(s).
C# - Loops: A loop statement allows us to execute a statement or group of statements multiple times .
Loop Type Description
while loop
Repeats a statement or group of statements while a given condition is true. It tests
the condition before executing the loop body.
for loop
Executes a sequence of statements multiple times and abbreviates the code that
manages the loop variable.
do...while loop Like a while statement, except that it tests the condition at the end of the loop body
nested loops You can use one or more loop inside any another while, for or do..while loop.
Loop Control Statements:
5. Page 5 of 8
Loop control statements change execution from its normal sequence. When execution leaves a scope, all automatic objects that
were created in that scope are destroyed.
Control Statement Description
break statement
Terminates the loop or switch statement and transfers execution to the statement
immediately following the loop or switch.
continue statement
Causes the loop to skip the remainder of its body and immediately retest its
condition prior to reiterating.
C# - Arrays:
An array stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it
is often more useful to think of an array as a collection of variables of the same type.
Instead of declaring individual variables, such as number0, number1, ..., and number99, you declare one array variable such as
numbers and use numbers[0], numbers[1], and ..., numbers[99] to represent individual variables. A specific element in an array is
accessed by an index.
Declaring Arrays:
To declare an array in C#, you can use the following syntax:
datatype[] arrayName;
where,
datatype is used to specify the type of elements to be stored in the array.
[ ] specifies the rank of the array. The rank specifies the size of the array.
arrayName specifies the name of the array.
For example,
double[] balance;
Initializing an Array
Array is a reference type, so you need to use the new keyword to create an instance of the array.
For example,
double[] balance = new double[10];
