Frequently Asked Questions
Q1: What is a compiler?
A1: Without changing the meaning of the program, a compiler translates the code written in one language to some other language. It is also expected that a compiler should make the target code optimized and efficient in terms of space and time.
Compiler design principles provide an in-depth view of optimization process and translation. Compiler design covers error detection & recovery along with the basic translation mechanism. It includes syntax, lexical,and semantic analysis as front end, and optimization and code generation as back-end.
Q2: Why to learn compiler design?
A2: Computers are a balanced mixture of software and hardware together. Hardware is a mechanical device and its functions are controlled by a compatible software. In software programming, hardware understands and follows instructions in the form of electronic charge. This is a counterpart of binary language. As we all know, binary language has only two alphabets, 0 and 1. To instruct and let the computer understand, the hardware codes must always be written in binary format, which is simply a series of ones and zeros. It would be very difficult and unmanageable task for computer programmers to write such codes. That is why we have compilers to write such codes.
Q3: What are the phases of a compiler?
A3: There are mainly two major phases of compilation. Each phases will take input from the output of the previous level and work in a coordinated way.
- Analysis phase – It is an intermediate representation which has been created from the given source code. There are four parts in it. Lexical, syntax, semantic analyzer and intermediate code generator are the types under analysis phase.
- Synthesis phase – In this phase, equivalent target program has been created utilizing the intermediate representation. There are two parts in it. Code optimizer and code generator.
