What is Compiler Design?

Compiler design is the field of computer science that mainly deals with the design and implementation of compilers, which are programs that translate source code written in a high and top-level programming language like c and c++ into machine code that can be executed and operated by a computer.

Compiler design involves several key activities, including:

Lexical analysis: This involves breaking down the source code into smaller units called tokens, which represent individual words, symbols, and operators.

Syntax analysis: This involves using the tokens to identify the structure and meaning of the source code and check for syntax errors.

Semantic analysis: This involves analyzing the meaning and context of the source code to ensure that it is semantically correct.

Code generation: This involves generating machine code or intermediate code that can be executed by the computer.

Optimization: This involves improving the efficiency of the generated code by reducing the number of instructions or making them more efficient.

Compiler design is a complex and challenging field that requires a strong understanding of programming languages, algorithms, and computer systems. It is an important area of study for anyone interested in programming languages, software development, or computer science in general.

Possibilities of Compilers: 

1. Correctness

2. Quickness of compiling

3. Maintain the right interpretation of the code.

3. The target code’s speed

4. Recognize programme structures that are lawful and illicit

5. A good reporting/handling of errors

6. Code fixing assistance

7. With the aid of a compiler, you can convert source code written in a high-level language into machine language.

8. Some crucial aspects of compiler design are correctness, speed of compilation, and preservation of the correct meaning of the code.

9. There are three categories for compilers. Compilers with a single pass Two-pass compilers and multipass compilers are more options.
