The Importance of Compiler Construction
A compiler performs two functions. First, it translates
source code written in one programming language into another programming
language that can be understood by the processor on which the program will run.
For example, compilers translate C++ code into assembly language and Java
source code into bytecode that can be interpreted by the Java Virtual Machine
(JVM). Secondly, compilers can help identify errors in source code before it’s
even executed, thus preventing bugs from reaching end-users and saving time and
money for developers as well as for organizations whose software products have
to work perfectly before being sold or deployed.
How does a compiler work?
The compiler takes code written in a high-level language
(such as Java or Python) and translates it into instructions that a computer
can execute. The translation process usually involves multiple stages,
including lexical analysis, parsing, semantic analysis, and code generation.
Each stage translates an aspect of human-readable source code into lower levels
of representation (machine code or assembly language). If you’re interested in
building your own compiler from scratch, understand that there are a number of
different approaches to each stage depending on your goal(s). For example, LLVM
is an open-source framework used for building compilers because it allows you
to work with all stages using a single API.
Why are compilers useful?
It may sound simple, but programming would be impossible
without compilers. They take complex instructions and make them user-friendly.
Without them, we’d still be working on punch cards. Today we’re going to talk
about how compilers work, why they’re so important, and where we might see their
role in computer technology going in the future.
Who uses compilers?
Programmers! They create source code that a compiler can
understand. That's why compilers are such essential tools in software
development. You see, source code is one thing. Another thing entirely is
machine code—the language computers actually speak. A compiler takes
human-readable source code and turns it into the machine-readable (and executable)
format. Without compilers, we'd have to create machine-readable versions of our
programs by hand. Of course, programmers would never do that! Instead, they
rely on their compilers to automate the translation process for them—allowing
them to focus on creating ever more complex software applications for all those
computers out there without having to worry about how computers really work
inside.
 Future directions in compiler technology
The purpose of compiler construction is to translate a
program expressed in a source language (the source code) into another form that
can be executed by a computer. This process involves reading and analyzing one
or more files containing some kind of programming language using various
algorithms to convert it into an equivalent program expressed in machine
language. Computer programmers need compilers to develop software since
computers do not understand high-level languages like Java or C++. A compiled
program will run on any computer which has a compatible operating system and
hardware platform; such programs are said to be portable, which saves time and
money on porting them from one computer to another.

The only difference is the additional tier(s), whereby marketers also earn a commission on sales generated by people they referred to the program. Affiliate Programs
