Originally released inthe language has grown and changed across 7 major versions. Once a knock off of Java in all but name has jumped out ahead on many aspects.
Throughout its life, the release of a new version of the language has been highly coupled with releases of new versions of Visual Studio as well as with releases of the.
This coupling has actually reduced the pace of innovation. If a feature was not quite ready for release by the time a cutoff was reached then it would be forced to wait for the next release which was, most likely, two years away.
Increasing Pace of C Releases Under, what many have called, the new Microsoft, the pace of innovation has increased. To achieve this, the developer division at Microsoft has decoupled a number of technologies which used to be shipped all together.
NET runtimethe compilers and the languages that compile to run on the runtime have all been split into their own packages and versions.
This means that each one can be released at its own cadence. We can see the success of this model already with the work done on. At almost the same time as. NET Core 2, C 7.
There is already work ongoing towards C 7. All this means that C 8 is quite a way off in the future. None the less we have a few ideas about what could be in C 8. All of the concepts in the article are proposals for inclusion in C 8 but some of them, or all of them, may not make it. The syntax is also the best guess and is subject to change.
The best source of information on the evolution of the C language is on the GitHub repository for the C language at https: Language design discussions are public and there is an extensive discussion in the issues section around new features. Check the milestones for which issues are tentatively scheduled for each release.
They provide a nice estimate of the future C roadmap. Primitives are the likes of int, char and double. These types cannot take on the value of null. Creating a new int without assigning a value will result in an int with a value of 0 rather than a null.
On the flip side, reference types any object such as string have always been able to take on a null value and have null as the default. This has the unfortunate disadvantage of allowing null references to sneak into applications.
New in C 8 will be an opt-in feature for making reference types non-nullable. Retrofitting a concept like this into C is quite difficult as it has the potential to cause compilation errors in code which have previously been fine. Thus what is needed is a way to create this functionality without creating an insurmountable amount of work for developers.
Per the design proposalthe C team has decided to take an approach of allowing developers to opt into nullable reference types. There will be a project level setting to enable validation of nullable references.
Once enabled, objects that can take on a value of null will need to be declared using the same? Write s ; Will cause a warning because String cannot take on a value of null.
Instead the code String? Write s ; Would need to be used. However, this code would also throw a warning because of Console.
Write is not expecting to receive a nullable string. In fact, the original code was likely in error so the cascade of warning is helping us avoid a runtime error. To me, this is the language change which has the most potential to improve the quality of code which is produced.
F has long been a favorite of mine for writing error free code because of just this avoidance of runtime null exceptions.
I suspect that the number of warnings one might find upon activating the opt-in on a larger code base will be disheartening but the errors should be quite easy to address and the resulting code more resilient. Records A nice new C 8 feature is a new way to create a C class called records.
They are essentially a very lightweight class that is a collection of fields. They help quickly create POCO type objects and also solve a key problem around comparing equality between objects.Feb 09, · Product Development Specialist mastering in various aspects of software development with extensive experience in full cycle of the software design process including requirement specification, prototyping, design, implementation, testing, and maintenance.
In computer science, write-ahead logging (WAL) is a family of techniques for providing atomicity and durability (two of the ACID properties) in database systems.
In a system using WAL, all modifications are written to a log before they are applied. Usually both redo and undo information is stored in the log.

Aug 24, · This is the way that we can write the rest of our system to work against our common interface, but yet still use a high quality, full featured logging system like log4net to take care of the actual work of writing our logging messages out to a file or a database or whatever we desire/5(36).
