Hi friends, I am working on a perl script to count the commented lines, blank lines and source lines separately. Let me know if you have one. For example i have a file containing the lines:
The script should read the file and count the Commented lines(/* */), blank lines and actual source lines. The expected output should be, Commented lines=9, Blank lines=2, Source Lines=6. Thanks in advance.

unifdef
unifdef(1) General Commands Manual unifdef(1)NAME
unifdef - remove preprocessor lines
SYNOPSIS
sym] sym] sym] sym]] ... [file]
DESCRIPTION
simulates some of the actions of in interpreting C language preprocessor command lines (see cpp(1)). For a valid preprocessor command line
contains as its first character a and one of the following keywords: or The character and its associated keyword must appear on the same
line, but they can be separated by spaces, tabs, and commented text. When appropriate, the portions of code surrounded by and including
the targeted preprocessor directives are removed, and the resultant text is written to the standard output.
Unlike does not insert included files, interpret macros, or strip comment lines. This means, among other things, that and macros occurring
within the input text are not interpreted.
Since is language-independent, it can be used for processing source files for languages other than the C language. For example, can be
used on FORTRAN language source files, provided the C language preprocessor commands are used.
Options
recognizes the following command-line options:
Complement the normal behavior by printing only the rejected lines.
Ignore text delimited by
sym. In other words, text that would otherwise be affected by some action is not touched when found within the context
of a preprocessor command using sym.
Ignore text delimited by
sym.
Replace rejected lines with blank lines
in the text written to the standard output.
Treat the input source as plain text.
C-language comment and quoting constructs are not recognized.
Define symbol
sym.
Cause symbol
sym to be undefined.
RETURN VALUE
The command returns the following exit values:
0 Output is an exact copy of the input.
1 Output is not an exact copy of the input.
2 The command fails. The failure might be due to a premature EOF or to an inappropriate or
EXAMPLES
Assume file contains the following:
The command sequence:
produces the following result in file
WARNINGS
Any symbol name defined in the file must be specified in the command line; otherwise, will ignore the line.
