METHOD FOR ANALYZING SYNTAX OF C PROGRAM

摘要

PURPOSE: The method for analyzing the syntax of the C program is provided to exactly divide the compiling and decompiling part according to the including time of a header file by preventing the lost of the macro information, calibrating a parsing tree, and separating the user defined header file from a C source file. CONSTITUTION: The processing is run in order to include the macro defined sentence to the C source file(200). A preprocessed file runs parsing by using the preprocessing command grammar(210). The parsing tree is created by using pure C grammar(220). The user defined header file is separated from the parsing tree and a line number is calibrated(230).
