These days very few programs are written in assembly language. Some parts of operating system kernels are written in assembly language usually because they need to perform some function very specific to a particular microprocessor architecture. Other programs written in assembly language include programs written for very cheap microprocessors in embedded systems. Such systems have very little resources and do not run operating system and compilers. Finally some specific parts of applications programs may be written in assembly language for performance optimization, but examples of those today are quite rare indeed.

No, there is no such thing as 'middle level language'. C is high level language, and it is no way similar to Assembly language.
A High level language is a language like C, Pascal, Fortran. To convert, the easiest way is to use a compiler. A compiler will take the instructions written in a high level language and convert them into machine code which is the specific instruction set for that type of computer. Assembly language is just a human readable form of a machine code which is how the designers of the computer instruction set made it work. A disassembler will show the assembly language from machine code. But the compiler usually includes a lot of optimisations from a the high level language and will not often generate very simple assembly.
The assembly language does not support object oriented program so they change to c and c++ the c++ will support object oriented program this are the demerits of assembly language.
A programming language that is machine-independent is called a "high-level" language - this includes Java, C++, Python, etc. A programming language that is machine-dependent is called a "low-level" language. For PCs, this usually includes assembly, binary code or some proprietary languages on embedded devices.
That depends on each individual compiler. Some are written in assembly, some in C/C++, others are written in whatever high-level language the author likes best.

Either in Assembly or in some high level language/the hex-code (for the mnemonics) that the microprocessor 8085 generally understands.
Unix is primarily written in the C language, with some small snippets of assembler code for low level bootstraps.

There are several different assembly languages. Some examples are MIPS, 86x, and RISK.

An assembler is used to convert low-level assembly language into machine code. Assembly language is a symbolic language that maps 1:1 with the machine code produced by the assembler. A compiler is used to convert a high-level language into a low-level language such as intermediate byte code, assembly or native machine code. An interpreter is used to convert a high-level language or byte code into native machine code. Statements are typically converted to machine code instructions one statement at a time, rather than all at once. All high-level are either compiled or interpreted, however some are both compiled and interpreted. Most compiled languages compile to machine code, however some, such as Java, compile to an intermediate byte code which must then be interpreted to produce the machine code.
Assembly language is used to write programs using the instruction set for a particular processor/controller.(example : 8051 or 8086 or MIPS).It is confined to a particular machine, it involves symbolic representation of the binary machine codes and other constants needed to program a given CPU architecture.Assembly Language require an ASSEMBLER to convert the assembly code to machine level code(HEX CODE)High Level Language require a Compiler to convert into ASSEMBLY THEN machine level code.(Now-a-days compilers are smart enough to generate the machine code directly)To write assembly code it is necessary to know the architecture of the processor or controller.To write an High Level Program it is not neccessay to know the architecture completly.Assembly language is not protable.High Level Language is Portable.with regardsMohan Kumar.JMCIS,MANIPAL.Assembly language is used to write programs using the instruction set for a particular processor/controller.(example : 8051 or 8086 or MIPS).High Level Language is used to write programs using some grammer rules or languages created like C,PASCAL,FORTRN,JAVA.Assembly Language require an ASSEMBLER to convert the assembly code to machine level code(HEX CODE)High Level Language require a Compiler to convert into ASSEMBLY THEN machine level code.(Now-a-days compilers are smart enough to generate the machine code directly)To write assembly code it is necessary to know the architecture of the processor or controller.To write an High Level Program it is not neccessay to know the architecture completly.Assembly language is not protable.High Level Language is Portable.with regardsMohan Kumar.,MCIS,MANIPAL.EACH HLL INSTRUCTION SPECIFY SEVERAL INSTRUCTIONS IN isa OF COMPUTER.

Machine languages consist entirely of numbers and are almost impossible for humans to read and write. Assembly languages have the same structure and set of commands as machine languages, but they enable a programmer to use names instead of numbers.Each type of CPU has its own machine language and assembly language, so an assembly language program written for one type of CPU won't run on another. In the early days of programming, all programs were written in assembly language. Now, most programs are written in a high-level language such as FORTRAN or C. Programmers still use assembly language when speed is essential or when they need to perform an operation that isn't possible in a high-level language.High-level language:-A high level language hides the micro abstractions such as set of command required to be performed by the processors such as CPU. Java and C++ are all high level languages.Java, C++ : all easy to write non-binary languagesExample : (i=10, i
