Static and dynamic storage allocation in compiler design code#

The difference lies in the way they read the source code or input. InterpreterĪn interpreter, like a compiler, translates high-level language into low-level machine language. It deals with macro-processing, augmentation, file inclusion, language extension, etc. PreprocessorĪ preprocessor, generally considered as a part of compiler, is a tool that produces input for compilers. The C compiler, compiles the program and translates it to assembly program (low-level language).Īn assembler then translates the assembly program into machine code (object).Ī linker tool is used to link all the parts of the program together for execution (executable machine code).Ī loader loads all of them into memory and then the program is executed.īefore diving straight into the concepts of compilers, we should understand a few other tools that work closely with compilers. User writes a program in C language (high-level language). Let us first understand how a program, using C compiler, is executed on a host machine. Similarly, an assembler is a program that converts the assembly language to machine-level language. A compiler is a program that converts high-level language to assembly language. The high-level language is converted into binary language in various phases. This is known as Language Processing System.

These programs are then fed into a series of tools and OS components to get the desired code that can be used by the machine. So we write programs in high-level language, which is easier for us to understand and remember. The hardware understands a language, which humans cannot understand. We have learnt that any computer system is made of hardware and software. It would be a difficult and cumbersome task for computer programmers to write such codes, which is why we have compilers to write such codes. To instruct, the hardware codes must be written in binary format, which is simply a series of 1s and 0s. Binary language has only two alphabets, 0 and 1.

Hardware understands instructions in the form of electronic charge, which is the counterpart of binary language in software programming. Hardware is just a piece of mechanical device and its functions are being controlled by a compatible software. Computers are a balanced mix of software and hardware.
