WebCompiler Design - Semantic Analysis. We have learnt how a parser constructs parse trees in the syntax analysis phase. The plain parse-tree constructed in that phase is generally of no use for a compiler, as it does not carry any information of how to evaluate the tree.

Common dynamically-typed languages include Groovy, JavaScript, Lisp, Lua, Objective-C, PHP, Prolog, Python, Ruby, Smalltalk and Tcl. Most type-safe languages include some form of dynamic type checking, even if they also have a static … WebProgramming languages such as C++, Java, and C#, also provide explicit control over scopes through the use of keywords like public, private, and protected. A block is a grouping of declarations and statements. C uses braces { and } to delimit a block, the alternative use of begin and end in some languages.
