1. INTRODUCTION
What is a compiler A computer program translates one language to another Source→ Compil Target er Program Program a compiler is a complex program From 10.000 to 1.000.000 lines of codes Compilers are used in many forms of computing Command interpreters, interface programs
What is a compiler? • A computer program translates one language to another • A compiler is a complex program • From 10,000 to 1,000,000 lines of codes • Compilers are used in many forms of computing • Command interpreters, interface programs Compiler Source Program Target Program

Why Compiler • Writing machine language-numeric codes is time consuming and tedious C7 06 0000 0002 Mov x, 2 X=2 • The assembly language has a number of defects – Not easy to write – Difficult to read and understand
Brief history of compiler The first compiler was developed between 1954 and 1957 The FORTRaN language and its compiler by a team at IBM led by John Backus The structure of natural language was studied at about the same time by noam Chomsky
