Input // input is from a file named inputslr. We will use C++ to write this program due to the standard template library support. This project implements a C++ code which builds an SLR (1) parser table, given the production rules of a grammar. The step involves in SLR (1) parsing is given below: Write a CFG for the given input string Check if the grammar is ambiguous or not. The reduce move is placed only in the FOLLOW of those variables whose production is reduced. In this post, we will write the program to generate an SLR parse table from CFG grammar. The SLR (1) parsing use canonical LR (0) item. It includes various methods like lexical, syntax, and semantic analysis as front end, and code generation and optimization as back-end. Compiler design covers everything from basic translation mechanism to recovery and error detection. The compiler also tries to make the program more efficient.Ĭompiler design principles give a detailed view of the translation and optimization process of a program. The parsing program reads character from an input buffer one at a time, where a shift reduces parser would shift a symbol an LR parser. A compiler is a program that translates the code that is written in one language to a machine code without changing the logic of the program.
