UNIT 1 1 What is compiler? Ans:- A compiler is a program that translates human readable source code into computer executable machine code. To do this successfully the human readable code must c omply with the syntax rules of whichever programming language it is written in. The compiler is only a program and cannot fix your programs for you. If you make a mistake‚ you have to correc t the syntax or it won’t compile 2 compare NFA and DFA ? Ans:DFA- single value transition function is represented

COMPILER CONSTRUCTION TOOLS INTRODUCTION: Writing a computer is tedious and time consuming task. There are some specialized tools for helping in implementation of various phases of compilers. These tools are called compiler construction tools. These tools are also called compiler-compiler‚ compiler-generator‚ or translator writing system.

Right from my school days I was much more interested in mathematics‚ science and IT workshops in our school scoring more than 90% marks in those subjects displayed my enthusiasm in those subjects‚ Simultaneously‚ I have completed computer language courses C and C++ at that very young age itself. Following my interest in those subjects I opted for mathematics‚ physics as my core modules in my higher education. I secured more than 80% in my two year intermediate. But‚ unfortunately

they are interested in how best to do things; we shall not be interested in optimality at all‚ but rather we shall be concerned with the question of possibility-what can and what cannot be done. We shall look at this from the perspective of what language structures the machines we describe can and cannot accept as input‚ and what possible meaning their output may have. This

computer or control system causing physical movement. (E.g. devices for opening windows in a computer controlled ventilation system) Algorithm – It is a sequence of instructions designed to perform a particular task and it is independent of any programming language. It includes precise details about the operations to be performed and in what order.
