• Are comments compiled in to C# Silverlight Applications

  - by LarryDev

  Is it safe to store information such as usernames and passwords within comments in your source code? I am not worried about some getting access to my source but I am concerned in regards to someone decompiling my compiled silverlight XAP file. Is anybody 100% sure if the compiler strips off commented code. I would assume it does but I want to be…

• Does string concatenation use StringBuilder internally?

  - by JamesBrownIsDead

  Three of my coworkers just told me that there's no reason to use a StringBuilder in place of concatenation using the + operator. In other words, this is fine to do with a bunch of strings: myString1 + myString2 + myString3 + myString4 + mySt... The rationale that they used was that since .NET 2, the C# compiler will build the same IL if you use…

• What are some lesser known usages of #pragma?

  - by Xavier Ho

  I've never understood the need of #pragma once when #ifndef #define #endif always works. I've seen the usage of #pragma comment to link with other files , but setting up the compiler settings was easier with an IDE. What are some other usages of #pragma that is useful, but not widely known?

• Why does Go compile quickly?

  - by Evan Kroske

  I've Googled and poked around the Go website, but I can't seem to find an explanation for Go's extraordinary build times. Are they products of the language features (or lack thereof), a highly optimized compiler, or something else? I'm not trying to promote Go; I'm just curious.

• Variable reference in a Groovy GString

  - by Maurits Rijk

  From the book "Groovy and Grails recipes" I'm using the following code snippet: String HelloLanguage = "def hello(language) {return \"Hello $language\"}" However, I get a compiler error "You attempted to reference a variable in the binding or an instance variable from a static context." because language can't be bound. What is wrong?

• Gimpel's PC-lint and Flexelint; Anyone used them?

  - by samoz

  So I've read a few magazine articles and the website for Gimpel's PC-lint and Flexelint C/C++ compiler. It's really expensive (at least for me), but it seems like it might have some merit to warrant the cost. So I'm wondering if anyone else has used/bought them and can provide their opinions?

  I have the following code snippet: enum { one } x; enum { two } y; x = y; That will compile in C, but in C++, I get the following error: test.c:6: error: cannot convert ‘main()::<anonymous enum>’ to ‘main()::<anonymous enum>’ in assignment Can someone explain to me why this is happening? I would prefer an answer with…

  I want to collapse or expand sub-sequences of a list e.g. ['A', 'B', 'D', 'E', 'H'] -> ['AB', 'DE', 'H'] and vice versa currently I wrote some ugly code like: while True: for i, x in enumerate(s): if x == 'A' and s[i+1] == 'B': s[i:i+2] = 'AB' break else: break For people who asking 'why do that thing':…

• Compilation error with C++ templates. Is there any easy way to understand them?

  - by Naveen

  While working with the C++ templates (most of the time using STL or boost) I run into the compilation errors that are miles long. I find it hard to figure out what compiler is trying to tell me. Is there any quick reference guide or a tool which can convert this error into something more understandable to humans?

• which RDBMS or other tool provides good SQL syntax error messages?

  - by zzz

  I use MySQL and it gives no meaningful error messages beyond "syntax wrong close to something or other". This is in sharp contrast to the sort of nice, clear error messages we are used to getting from java compiler and similar. So, are there RDBMS or sql validation tools that provide clearer, meaningful error messages?

• Is possible to generate constant value during compilation?

  - by AOI Karasu

  I would like my classes to be identified each type by an unique hash code. But I don't want these hashed to be generated every time a method, eg. int GetHashCode(), is invoked during runtime. I'd like to use already generated constants and I was hoping there is a way to make the compiler do some come computing and set these constants.…

  I'm reading a compiler book and kinda confused when it says "a S-attribute grammar is also a L-attribute grammar". Couldn't understand. Can someone make it clear (an example should be great). Thanks.

• problem understanding templates in c++

  - by hidayat

  Template code is not compiled until the template function is used. But where does it save the compiled code, is it saved in the object file from which used the template function in the first place? For example, main.cpp is calling a template function from the file test.h, the compiler generates an object file main.o, Is the template…

• Why compile + link when build a C++ code, instead of generating executable directly

  - by Dbger

  I was asked of this question when mentor an entry-level programmer, I was thinking of this compile + link process so official and usual that I never think about why. One thing I could think of is to improve the development productivity, but should there be any other more compiler-related reasons?

• Easy way to convert c code to assembly?

  - by Bob

  Is there an easy way (like a free program) that can covert c/c++ code to x86 assembly? I know that any c compiler does something very similar and that I can just compile the c code and then disassemble the complied executable, but that's kind of an overkill, all I want is to convert a few lines of code. Does anyone know of some…

• Invalid use of 'void' in C++ when using struct and classes

  - by Aaron Haaf

  I have 1 compiler error. It is from this line in my code: cout << myClass->Get_Type().discription; Where as Get_Type() is: void Tile::Get_Type() { return &myStruct; } I'm not quite sure what I am doing wrong. Or what for that matter could be going wrong.

• 'Invalid conversion from some_type** to const some_type**'

  - by petersohn

  I've got a function that requires const some_type** as an argument (some_type is a struct, and the function needs a pointer to an array of this type). I declared a local variable of type some_type*, and initialized it. Then I call the function as f(&some_array), and the compiler (gcc) says: error: invalid conversion from…

• Is it possible to write apps for Android in C# ?

  - by Roberto Sebestyen

  We all know that Android runs Dalvik VM programs. Normally developers write programs in Java and they compile it to Dalvik bytecode. I wonder if it would be possible to create a compiler that can take C# code and compile it into Dalvik bitecode.
