Java) morph the program not into a machine code but into a program in a certain low level language. The architecture (a set of program means) for which a compilation is executed is called an object machine. Normally this code should also be executed in the specific operation system environment since it uses the opportunities provided (system calls, function libraries). Most compilers morph the program from a certain high level programming language onto a machine code which can be directly executed by the central processor. It immediately gained popularity among programmers as it was generating codes faster than all the others. A year later Watcom was founded which in 1988 presented the C compiler. In 1980 a new version was developed for IBM 360 and IBM PC, which supported the FORTRAN 77 standard. The compiler worked on IBM 7040, IBM 360 and DEC PDP-11. The year 1957 can be considered a birth year for the compilers theory when the first compiler of the Fortran language appeared, which was created by Backus and providing a good working object code. Primarily, the purpose of creating compilers was to transform mathematical formulae into the machine code. It is difficult today to figure out when the first compiler appeared since at that time there were lots of experiments and layouts carried out by different groups. Initially, compilers appeared at the beginning of the 1950s.

Besides, some of them are special languages of a high level which are convenient to describe algorithms used in the production of compilers. Usually, the syntactical translation mechanism is being used in the CCs. The CC source code is just a formality used to describe compilers containing lexical or syntax analyzers, code generators and other parts of the compiler produced. The CC is often being referred to as the programming language where the source code is a description of a language’s compiler, and the object program in the language compiler itself. Besides, there are also special languages of compilers design – the so-called “compilers of compilers”.Ī compiler of compilers (CC) is a system which allows a compiler generation there is a variety of grammars at the system input, and ideally, there is a program at the output. Online Java Compiler is a system program which “translates” a program in a certain algorithmic language to one in a language close to an artificial language which is, to some extent, equivalent to the initial one. Compilers are being written both on the autocode, and in high level languages.
