A compiler takes as input a source program and produces as output an equivalent sequence of machine instructions. This process is so complex that it is divided into a series of sub-processes called phases. The different phases of the compiler are as follows: Phase 1: Lexical Analyzer or Scanner The first phase of the compiler‚ called Lexical Analyzer or Scanner reads the source program one character at a time‚ carving the source program into a sequence of atomic units called tokens. The usual

The compiler has a number of phases plus symbol table manager and an error handler. Input Source Program ↓ Lexical Analyzer ↓ Syntax Analyzer ↓ Symbol Table Manager Semantic Analyzer Error Handler ↓ Intermediate Code Generator ↓ Code Optimizer ↓ Code Generator ↓ Out Target Program The cousins of the compiler are Preprocessor. Assembler. Loader and Link-editor

tiny mistake that the programmer has committed while typing the code. * The compiler follows a detailed procedure using the tokens creates by the lexical analyzer and creates a tree-like structure called the syntax tree. * The syntax analyzer checks whether the order of tokens conform to the rules of the programming language. Unmatched parenthesis‚ missing semicolons are some of the errors detected in this phase. * If there are no errors in the code‚ the syntax analyser successfully constructs

as Phase Diagrams By _________________ _________________ Material Science Lab #11 Report Introduction The purpose of this lab is to obtain the cooling curves for tin‚ lead and various alloys of these two metals. A phase diagram will be generated from these cooling curves. When a material is heated by adding energy at a constant rate‚ the temperature of the material will increase linearly with time‚ provided a phase transformation does not occur. As temperature of the sample becomes

Explain the structure and behaviour of water Similar to many other substances and liquids‚ water takes on numerous forms. It can either be solid as ice‚ gas as steam‚ and its usual liquid phase‚ water. Water molecules are electrically neutral and V-shaped with molecular formula H2O. In water‚ each hydrogen atom is bound to the oxygen atom by an

Paragraph 1 Quartz-type iron phosphate‚ FePO4‚ exists in different phases at different temperatures. At low temperatures‚ it exists in the α-quartz-type phase‚ while at high temperatures‚ it exists in the β-quartz-type phase. The α-β phase transition occurs at 980K. In terms of lattice symmetry‚ α-FePO4 exhibits a trigonal lattice system‚ whereas β-FePO4 exhibits a hexagonal lattice system. In terms of space symmetry‚ α-FePO4 belongs to the P3121 space group‚ while β-FePO4 belongs to the P6422 space

It’s a Tuesday. I’m finishing my workout at my neighborhood gym. I walk into the locker room‚ throw my clothes off‚ and head to the showers. The water is warm. I’m feeling like a real go-getter. The endorphins‚ the steam – it’s relaxing. Veeery relaxing. I take a handful of the shower gel that the gym supplies in buckets and start lathering up. I’m making sure things are clean down there. Really‚ really clean. (Not really‚ readers – I’m jerking off. Duh.) So I’m a showerbater; I admit it. I like
