C# 9 Deep Dive: Init-only features

A few weeks ago, we took a quick tour of some upcoming C# 9 features that will make your development life easier. We dipped our toes in the water. But now it’s time to dig a little deeper.

I’m starting a new series over the next several weeks, that will showcase all of the announced features incrementally. Then, we will tie it all together with an all-in-one app. As for the features we are showing off, we could always dig deeper by what we see in the Language Feature Status in GitHub, but the publicly-announced-at-Build features will most likely make it when .NET 5.0 launches in November 2020.

Let's Give Some Unit Testing Love to C# 8 and C# 9 Features

According to StackOverflow, C## is one of the most-loved programming languages. And I completely understand that—it is powerful, easy to learn and consistently improving and developing. It is a living language. :)

The last couple of years, there were new features added to the languages, and the new versions keep coming up—C## 7, C## 8, C## 9.

As you know, we at Progress Telerik are proud that our products are always in sync with the latest things in the .NET world, and C## 9 and JustMock are no exception.

How to Run C/C++ in Sublime Text?

C and C++ are the most powerful programming language in the world. Most of the super fast and complex libraries and algorithms are written in C or C++. Most powerful Kernel programs are also written in C. So, there is no way to skip it.

In programming competitions, most programmers prefer to write code in C or C++. Tourist is considered the worlds top programming contestant of all ages who write code in C++.

During programming competitions, programmers prefer to use a lightweight editor to focus on coding and algorithm designing. Vim, Sublime Text, and Notepad++ are the most common editors for us. Apart from the competition, many software developers and professionals love to use Sublime Text just because of its flexibility.

I have discussed the steps we need to complete in this blog post before running a C/C++ code in Sublime Text. We will take the inputs from an input file and print outputs to an output file without using freopen file related functions in C/C++.

Dicey Issues in C/C++

If you are familiar with C/C++then you must have come across some unusual things and if you haven’t, then you are about to. The below codes are checked twice before adding, so feel free to share this article with your friends. The following displays some of the issues:

1. Using multiple variables in the print function
2. Comparing Signed integer with unsigned integer
3. Putting a semicolon at the end of the loop statement
4. C preprocessor doesn’t need a semicolon
5. Size of the string matters
6. Macros and equations aren’t good friends
7. Never compare Floating data type with double data type
8. Arrays have a boundary
9. Character constants are different from string literals
10. Difference between single(=) and double(==) equal signs.

---

The below code generates no error since a print function can take any number of inputs but creates a mismatch with the variables. The print function is used to display characters, strings, integers, float, octal, and hexadecimal values onto the output screen. The format specifier is used to display the value of a variable.

1. %d indicates Integer Format Specifier
2. %f indicates Float Format Specifier
3. %c indicates Character Format Specifier
4. %s indicates String Format Specifier
5. %u indicates Unsigned Integer Format Specifier
6. %ld indicates Long Int Format Specifier

---

A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a non-negative integer in the range [0 to 4294967295]. The signed integer is represented in twos-complement notation. In the below code the signed integer will be converted to the maximum unsigned integer then compared with the unsigned integer.

ICYMI C# 9 New Features: Top-level Statements

This is the first in a series of articles on new features introduced in C#9.

Top-level statements allow you to simplify and remove some of the “ceremony” in your code.

For example, take the following console application written in C#8:

?

using System.Linq;

using static System.Console;

namespace ConsoleAppCS8

{

class Program

{

static int Main(string[] args)

{

string greeting = ""``;

if (args.Any())

{

greeting = args[0];

}

WriteLine(``"Please enter your name"``);

var name = ReadLine();

var upperName = ConvertToUpper(name);

WriteLine($``"{greeting} {upperName}"``);

return 42;

}

public static object ConvertToUpper(string name)

{

return name.ToUpperInvariant();

}

}

}

In the preceding code the “ceremony” consists of things such as the enclosing namespace, the Program class outline, and the Main method itself.

With top-level statements in C## 9 this code can be simplified to the following:

?

using System.Linq;

using static System.Console;

string greeting = ""``;

if (args.Any())

{

greeting = args[0];

}

WriteLine(``"Please enter your name"``);

var name = ReadLine();

var upperName = ConvertToUpper(name);

WriteLine($``"{greeting} {upperName}"``);

return 42;

static object ConvertToUpper(string name)

{

return name.ToUpperInvariant();

}

Notice in the C## 9 version that the structure is a lot “flatter” because there are no nested {} from the namespace, class, and Main method.

The application will still act in the same way, there is just less boilerplate code.

Loops in C++ | For, While, and Do While Loops in C++

In this Video We are going to see how to use Loops in C++. We will see How to use For, While, and Do While Loops in C++.
C++ is general purpose, compiled, object-oriented programming language and its concepts served as the basis for several other languages such as Java, Python, Ruby, Perl etc.
