Write a LEX program that does the following:
1. Reads a C++ program, numbers all lines.
2. Finds all identifiers in the program.
3. Lists all identifiers that are NOT C++ keywords, and the
line or lines on which each identifier appears.
NOTES:
- Each identifier name should appear only once in the list.
- Anything inside a comment (// or /* ... */) should be
ignored.
- Although not mandatory, a sorted list of identifiers is easier
to check.
- You do not have to check for correct C++ syntax; however text that
does not match the definition should be ignored (e.g. numbers,
bad variable names, garbled text).
OUTPUT:
1. Program listing with line numbers.
2. List of identifiers with line(s) on which each identifier appears.
DELIVERABLES:
Program source code, with internal documentation
Test results
After that I want to make three different version
.
