   • Why is C used as the main programming language for operating systems?

     Top Answer

     Answered Dec 30, 2013 · 14 votes

     C is the language most like the machine code while still maintaining portability between different architectures.

     Here are some features of C that are not seen in many other languages that make it suitable for OS developement:

     • Direct memory access. Memory management is left to the programmer and therefore is an advantage in OS development where practically all things useful involve directly manipulating areas of RAM. Examples included Memory mapped IO, DMA controllers, page tables, etc. If these things cannot be directly represented by C structures, they can at least be accessed with C pointers.
     • No runtime dependencies. Unlike C++, Java, C# and others, C has absolutely no runtime dependencies. It doesn't expect a memory manager, it doesn't expect process management, the only runtime dependency it has is that something calls the main() function. That means that you can write a C program that runs directly on hardware without expecting some kind of memory manager or input or output layer. This of course means that you have to implement your own, but nonetheless this is possible unlike in other languages. Much of the standard library doesn't require an operating system (ie string.h), while those parts that do can be implemented minimally by the programmer in OS development.
     • Efficient byte-level manipulation. C is perfectly suitable at efficient byte level manipulation. That is, copying data to different areas, flipping bits around, and processing data in small amounts. While this is more tedious for the programmer, it is much more efficient both in usage of RAM and in processing time, which is essential in Operating Systems.
     • All C code has a direct 1-1 translation to machine code that is easily understandable. As a result, C has no built in complicated data structures like trees or hash tables. This must be implemented by the programmer, the premise behind this being that the programmer should be able to see any C code and know exactly what it does in hardware. This doesnt occur in other languages like Python for example that has things such as the "Dictionary" datatype whose backend implementation is not necessarily known to the programmer. The C (and UNIX) philosophy is that the programmer knows better than the language, and this makes it very suitable for fine tuning details in OS and systems development, with the obvious downside of not having convenient structures built in.

   • Why is 'int' used as just int and why not as std::int in C++?

     Top Answer

     Answered Mar 09, 2020 · 12 votes

     Keywords such as int and return and the main() function are all included in the C++ standard. std does not mean that only those things are standardized. Instead, it refers to the things that are in the standard library (which, like keywords, is a part of the standard). Include files such as #include <vector> are needed to use the standard library, but keywords can be used without any #includes.

   • Why is an integer always used as the controlling variable in a for loop?

     Top Answer

     Answered Nov 17, 2010 · 28 votes

     In C, an "int" is defined as the most efficient integer type for the current machine.

     It usually match the registers of the CPU, that's how it is the most eficient.

     Using a smaller type of integer value may result in some bit-shifting or bit masking at the CPU level so you would get no gain...

   • why there is no check to see if the subscript used for an array exceeds the size of array in c language?

     Top Answer

     Nope, this is undefined behavior. And well that's why it may work and it may not. (Depends on the moon). You should avoid it. Don't think that this is making your program work by allocating more memory - it doesn't.

     If you write this, you are writing in some part of your program's memory which will in turn result in errorneous result or if it is trying to write to some memory which is non-modifiable, you will get error. In either way you are invoking undefined behavior - anything may happen from crashing your code to a correct execution. Don't rely on that.

     so if it's not allocating memory so where he is storing the elements. I just want to know what is happening internally in the system??

     Well it is writing to the memory out of the bound of the array where it is not supposed to write. That is what is happening. That is why this is not what you should be doing. You are basically changing part of memory that program is being assigned and moreover which you are not supposed to change.

   • Why is %c used in C?

     Top Answer

     Answered Jun 08, 2012 · 31 votes

     Because %d will print the numeric character code of the char:

     printf("%d", 'a');-

     prints 97 (on an ASCII system), while

     printf("%c", 'a');

     prints a.

   For example, C is the intermediate language underlying Eiffel and Forth. This means that, instead of generating machine code for every architecture to be supported, compilers for those languages just generate intermediate C code, and the C compiler handles the machine code generation.
