Project #2 Calling Sequences
BSpecification , CSpecification , code due Oct 22th, 2001
Purpose:
This program analyzes syntactically correct C and C++ code to determine calling sequences, that is, what functions call what other functions. Given a list of source code files on the command line, its output starts by listing all functions defined in any of the files which call no other functions, if any. It then continues with listing all functions defined which call no functions defined in any of the files. Then, it continues by listing all functions which call only functions cited previously in the program's output or itself (recursive call). Note that a recursion which spans more than one file, for example A calls B and B calls A, cannot be placed in such an order. We will agree to call such sequences indirect recursions. Functions participating in indirect recursion shall be placed together, but after all functions they call that are not in the indirect recursion sequence. Please display each function on a separate line, and follow with a list of all the functions it calls directly, e.g.: Fun1: Fun2: Fun3: Fun1 Fun3, Fun1 Fun4: Fun3, Fun2 :
Requirements:
Your CALLS program: 1. 2. Shall compile and link, using Visual C++, as provided in the ECS clusters, e.g., version 6.0, SP 5. Shall process each file pattern cited on the command line. That entails finding matching files for each pattern and attempting to open each file and processing according to the following requirements. Shall issue an error message for each file which cannot be opened. Shall display each function defined in any of the files cited on the command line, provided that those files can be opened by the CALLS program. Shall order the display of functions as described in the Purpose section, above. Shall mark all ...
