C Language Code line number classification statistics small program (source code) __ Applet

1 Requirements Analysis
1) Problem Description:Read a (up to 9) C program code file, statistics program code, comments and number of empty lines and functions, display function name and generate the corresponding log.
2 The basic requirements are as follows:
(1), the program files (such as. C or. txt, etc.) read into the source program in the order of character;
(2), input correctness check;
(3), Edge reading program, the edge of the identification of statistical code lines, comment lines and blank lines, but also to identify functions, statistics code number;
(4), allow analysis of 9 files at a maximum


2 Display Results
Note: The code Test IDE for this article is VS2013. This code to the more conventional programming habits of the written C code can be better recognized, but for some special circumstances can not identify.

1 Enter the correct number of files and path

2 Enter the correct log file generated
