How to add LCOV_EXCL_LINE marker for code coverage in C or C++ code?

Question

I tried two ways to add LCOV_EXCL_LINE in my code.

I add it as comment, compile and generate lcov report but lcov binary takes it as a comment and showing the coverage of excluded line.
Image showing coverage of excluded line:
After compilation and execution I add LCOV_EXCL_LINE before running lcov and genhtml binaries but it results in misalignment after first exclusion.
Image showing misalignment coverage:

I am taking coverage of compiler front end source code, their are multiple directories and files. For other references I just wrote a code(images attached) and did exactly the same thing what I did in my source code. I guess that is explainable, I am not getting how to add this marker. Did u know that ? — Aakash Shah, May 09 '18 at 08:42

You add the comment in the line you want excluded. Not in the line before that you want excluded.

As 1737973 said, you should do something like:

printf("* ")  // LCOV_EXCL_LINE
printf("\n")  // LCOV_EXCL_LINE
