In C language, the integer takes 2 bytes for a 32-bit compiler and 4 bytes for a 64-bit compiler. The float always takes 4 bytes. The character always takes 1 byte. So why is there only variation in the case of integers?
Umm, not always. 32-bit compilers also use 4 bytes as the size of an int.Actually the C language standard says that an int must be at least 16-bits wide. But it doesn't say it has to be exactly n-bits wide. So compiler writers generally go with the word size of the underlying machine - which is 32 bits on most machines today. (Word size is, loosely speaking, the number of bits the processor can physically process at one shot)Coming to why this is so (why int is the only type without a fixed size), int is the only type where you do not 'interpret' the bits stored in memory. The char type uses ASCII encoding. This encoding was not defined by the C language committee, but since they chose to use it, they had to go with ASCII's 1byte wide characters. So the size of a char was fixed. Storage and encoding of float and double are also defined by IEEE standards, so the C language committee had to fix the size of float to 4 bytes. But when it comes to integral types, there is no encoding standards that specifies the number of bytes to use. So the C language committee chose to leave it undefined to allow compiler writers enough leeway to optimise code according to underlying architectures. It is very truly said that C leans towards the convenience of the compiler writer rather than of the high level user. Accordingly, you see compilers merrily changing the size of int, long and long long according to convenience and underlying architectures, but not messing with ASCII or IEEE.
What does Windows 8.1 Single Language mean?
windows 8.1 Single Language means Single Language option in OS ,however you can change the languages of your choice at any time , but you have to reset to factory settings and then have to do the things to change your language . Almost this functionality is similar in other versions of windows also. The major variation of windows 8.1 single language and other versions of windows 8.1 (Professional,Enterprise) lies in the extended development and management functionalities provided with professional /Enterprise versions. You can't use a single language edition , if you want to develop apps for windows platform . In short , windows 8.1 single language is similar to a Windows 7 Home premium version , bets optimized for Home users . For changing language you can more details in my blog below.Some tech tips
Which is the best C compiler for Windows 8?
All depends on what you mean by "best" as it all depends what you care about/consider to be important. If price is your guide, then a freebee like GCC or LLVM is likely to be considered your "best" option, although you might not have all of the same features as other compilers. But in those cases, besides price, it also helps that functionally the compiler will have pretty much the same input syntax no matter what the target OS (Windows, UNIX etc.).If you want pure performance of the output code (ie. fight/win the benchmark wars, make your customers happy for the speed of a your product), a commercial compiler such as Intel's icc (i.e. "Composer") is used by many firms and app developers regardless of the target chip. It and its companion ifort (Fortran) are often considered the "best" choices if code generation is the key (although they don't always win - the folks at Intel take code generation very seriously and if you find placed where they are not generating the best code, you can file bug reports and they do look into it when I have done so). Also this compiler will generate code for parallel devices such as Intel's Phi so, there are lots of tools for going from pure serial execution to parallel code; which many other tools suites lack. But while there is a free version to try out, you will need to pay for it.Finally, MSFT's Visual C is the default since its what the target OS developer uses themselves. Its a fine tool, well integrated with Windows and probably the most popular by # of users - so many people consider it the "best" for that reason.As always, "your mileage may vary" but it's worth doing a little investigation and thinking a bit about what your care about. Then looking at comparisons over that set of criteria.
Which is the best C++ compiler for Windows 8 and above?
Answers mentioned here talk about IDE (Codeblocks, Eclipse etc) while you have asked about the compiler.What is the difference between a compiler and an IDE?Here is a link to the list of C++ compilers from Bjarne Stroustrup himself.Link: C++ CompilersYou have a lot of options amongst paid and free open source compilers. So you must choose one according to your needs and requirements. I doubt if anyone can give you a single “best compiler” as it depends on what you are using C++ for(Programming Contests, Web, Games etc).I use C++ for algorithmic programming competitions, so my choice is gcc with Codeblocks IDE.
How do you run your first assembly language program on a 64-bit Windows operating system?
As a new learner of assembly language, it is little bit trouble to run your first program specially at 64 bit operating system. Now I show you how to run your first program.First of all download the following two files:1. MASM2. DosBox->Now extract the 8086 (MASM) download file to c drive->Install the DOSBox0.74and see the following link-Running first assembly language program using 8086 MASM assembler at windows 7 (64 bit).
How can I download Turbo C for Windows 10?
How can I install Turbo C on Windows 10?You don’t. It was succeeded by Turbo C++ in 1990 (!), and Turbo C++ was had its last release in 2006 (!!). If you really, really, really need to use Turbo C for some reason, you would need to install it under an old version of Windows or in a DOS emulator, but you should almost never need to use Turbo C or Turbo C++ in 2018.If you want to work in C, you should use either MinGW-W64 (a Windows fork of GCC) or Clang with your IDE of choice. Code::Blocks is popular, JetBrains has CLion, or you can use Visual Studio with its own compiler or one of those I mentioned previously. If you decide to use Visual Studio, just bear in mind that its C compiler is somewhat lacking, given that it doesn’t completely implement the most recent C standards, but its C++ compiler is probably on par with MinGW and Clang.
