How Do I Prevent the User from De-compiling My C# Application?

How do you prevent your code from being stolen? How do you stop people from decompiling your application? How do you protect your intellectual property? These are the questions we will tackle in this episode of Dev Questions.

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.

Behind the compiler: 20 examples of C# code before and after compiling

Over years I have written many blog posts about C# and .NET that demonstrate also how things work internally and what C# compiler produces from the code we write. I have called these chapters usually as “Behind the compiler”. This post is growing list of my writings covering interesting findings about C# compiler work.

Compilation of a C program - Behind the 'screen'

First, what is compilation?

**Compilation **is an automated process of conversion of a source code (script) into an object code.

In software terms, a Compiler compiles a script i.e. it converts the source code into object code. But, before the conversion, it checks for the presence of any syntax errors in the code, after which the code is converted into an object code.

Let us now have a look at the various phases of compilation.

Source Generators Will Enable Compile-Time Metaprogramming in C#

Source generators are a new feature of the C# compiler that enables inspecting user code using compiler-generated metadata and generating additional source files to be compiled along with the rest of program.

Loosely inspired by F# type providers, C# source generators respond to the same aim of enabling metaprogramming but in a completely different way. Indeed, while F# type providers emit types, properties, and methods in-memory, source generators emit C# code back into the compilation process.
