Murus, on the other hand, helps to use PF feature to convert the network firewall into an application firewall wherein you can allow or restrict movement of data packets for each application individually which even helps in restricting spreading of virus, worms or data leak by an application.Price: Murus comes in three versions: Murus Lite (Free), Murus Basic ($10), and Murus Pro ($17). And by restricting the network functions itself, it affects all the applications. Common firewalls like Mac’s own PF, restrict and monitor the inbound and outbound network traffic based on attributes like IP address, ports, protocols etc. Well, here’s the catch. While Murus lite is the free version of the application, Murus Basic and Murus Pro are the paid versions that come packed with some extra features like logs Visualizer, Vallum, and all companion apps.Check it out here: 2. 
Infinite While loop. A while loop that never stops is said to be the infinite while loop, when we give the condition in such a way so that it never returns false, then the loops becomes infinite and repeats itself indefinitely. An example of infinite while loop. For loop in C programming with example: A loop is used in a programming to execute set of statements repeatedly until a given condition returns false. The foreach loop in C or more specifically, range-based for loop was introduced with the C11.This type of for loop structure eases the traversal over an iterable data set. It does this by eliminating the initialization process and traversing over each and every element rather than an iterator. C for loop - A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.
Originally released by Bloodshed Software, but abandoned in 2006, it has recently been forked by Orwell, including a choice of more recent compilers. It can be downloaded from:
http://orwelldevcpp.blogspot.comInstallation
Run the downloaded executable file, and follow its instructions. The default options are fine.Support for C++11
By default, support for the most recent version of C++ is not enabled. It shall be explicitly enabled by going to:Tools -> Compiler OptionsHere, select the 'Settings' tab, and within it, the 'Code Generation' tab. There, in 'Language standard (-std)' select 'ISO C++ 11':
Ok that. You are now ready to compile C++11!
Compiling console applications
To compile and run simple console applications such as those used as examples in these tutorials it is enough with opening the file with Dev-C++ and hitF11.As an example, try:
File -> New -> Source File (or Ctrl+N)There, write the following:
Then:
File -> Save As.. (or Ctrl+Alt+S)And save it with some file name with a
.cpp extension, such as example.cpp.Now, hitting
F11 should compile and run the program.If you get an error on the type of
x, the compiler does not understand the new meaning given to auto since C++11. Please, make sure you downloaded the latest version as linked above, and that you enabled the compiler options to compile C++11 as described above.Tutorial
You are now ready to begin the language tutorial: click here!.C++ while loops statement allows to repeatedly run the same block of code until a condition is met.
while loop is a most basic loop in C++. while loop has one control condition, and executes as long the condition is true. The condition of the loop is tested before the body of the loop is executed, hence it is called an entry-controlled loop.
