What optimizations does the C# compiler perform when you use the /optimize+ compiler option?

  
The following is a response from a developer on the C# compiler team: We get rid of unused locals (i.e., locals that are never read, even if assigned). We get rid of unreachable code. We get rid of try-catch with an empty try. We get rid of try-finally with an empty try. We get rid of try-finally with an empty finally. We optimize branches over branches: gotoif A, lab1 goto lab2: lab1: turns into: gotoif !A, lab2 lab1: We optimize branches to ret, branches to next instruction, and branches to branches. (More...)

What are the different compiler generated methods when a .NET delegate is compiled?

Invoke()
BeginInvoke() and
EndInvoke(). (More...)

What is the role of compiler?

  
Compiler translates a high level language into machine language. (More...)

what is the difference between compiler and interpreter?
give any one example for interpretter?

  
An interpreter reads each line of the source code and
converts it to machine code on the fly. This happens every
time the programme is run. Consequently it is very slow as
it is converting source code to machine code while the
programme is running.


A compiler does it once and thats it.

DOS BASIC is an example for interpretter. (More...)

is JavaScript a compiler or interpreter.if so why?

  
javascript is a scripting language that executes on client browser.
its a interpreter language whereby script executes before compilation (More...)

What is JIT compiler

  
It is a compiler which converts MS IL code to Native Code (ie.. CPU-specific code that runs on the same computer architecture). Just-In-Time compiler- it converts the language that you write in .Net into machine language that a computer can understand.
