They direct the pre-processor about what to do. These (#) tags are called preprocessor directives. They are closer to humans but far from machines. High-Level Language – If a program contains #define or #include directives such as #include or #define it is called HLL.This is where language procedure systems come in handy. Now, these programs go through a series of transformations so that they can readily be used by machines. The hardware knows a language, that is hard for us to grasp, consequently, we tend to write programs in a high-level language, that is much less complicated for us to comprehend and maintain in thoughts. We know a computer is a logical assembly of Software and Hardware. Language processing systems (using Compiler) – Source-to-source Compiler or transcompiler or transpiler is a compiler that translates source code written in one programming language into the source code of another programming language.It is capable of creating code for a platform other than the one on which the compiler is running. Cross Compiler that runs on a machine ‘A’ and produces a code for another machine ‘B’.The compiler is software that converts a program written in a high-level language (Source Language) to low-level language (Object/Target/Machine Language).
