Difference Between C++ and C++ Standard

[PainterGuy]

hello everyone,

i was reading somewhere that there is C++ and C++ Standard. could some please tell me the main difference between two? and i also read something that some things such as "getch()" are non standard. can you guide me a bit on this? i will really appreciate this help of yours.

cheers

As far as I know there are standards that relate to the grammar of the syntax and functionality of the language. I'm not sure if its an ISO or ANSI standard, but if you want to adhere to that standard then the compiler has to meet those certain requirements.

Also C++ comes with what is known as a standard template library and provided your compiler adheres to the right standard, the STL should work the same for every standard-meeting compiler.

The other standard library for C++ is the C++ standard library which has a lot of C++ specific things as well as inheriting the C standard library which has a tonne of functions that deal with things ranging from routines dealing with files to memory allocation and other common routines that do your basic standard OS type things.

I don't know what the getch() function refers to, but I'm guessing its some kind I/O function that gets a character from an I/O source.

I'm sorry I can't answer your question specifically, but if you want to see the C++ standard that has to be enforced for the various compilers out there, you should do yourself a favor and look up the ANSI and ISO standards for C++.

The other standard library for C++ is the C++ standard library

Standard C++ is defined by a committee of the ISO. The current standard dates to 1998. It defines both the C++ language itself, and the C++ standard library. There is a draft for a new standard which will probably become official in the next year or two. Many of the features of the new standard are available in g++ (GNU C++) 4.6 which was released last week, and there's a thread here discussing some of those features.

The C++ standard library includes most or all of what was once called the "standard template library" (STL), which was designed before the first C++ standard appeared in 1998.

Individual compilers (Microsoft, GNU, etc.) often include non-standard "extensions" to C++. Some of them are anticipated features in the next standard. Others are intended for programming on specific platforms such as Windows.

many many thanks, chiro and jtbell. it helped me. and chiro you shouldn't be sorry because i was able to understand some stuff which could and it was useful. and that's what matter.

okay much grateful for this teaching. will ask any related questions here whenever i have some.

cheers

Hello there! I can provide some insight into the difference between C++ and C++ Standard. C++ is a programming language that was developed in the late 1970s and is still widely used today. It is a high-level, general-purpose language that is commonly used for developing applications, operating systems, and other software.

C++ Standard, on the other hand, refers to the official standard for the C++ language, which is maintained by the International Organization for Standardization (ISO). This standard specifies the rules and guidelines for writing C++ code, ensuring that code written in this language is consistent and can be easily understood by other developers.

One of the main differences between C++ and C++ Standard is that C++ is a language, while C++ Standard is a set of rules and guidelines for using that language. This means that C++ Standard is constantly evolving and being updated, while C++ remains the core language.

In terms of the "getch()" function, it is a non-standard function that is commonly used in older versions of C++. This function is not part of the official C++ Standard, but it is still supported by many compilers. However, it is recommended to use alternative functions that are part of the C++ Standard, such as "cin" for input and "cout" for output.

I hope this clarifies the difference between C++ and C++ Standard for you. If you have any further questions, please don't hesitate to ask. Happy coding!
