gcov is a test coverage program by gcc that generates
statement-by-statement profiling.
(https://gcc.gnu.org/onlinedocs/gcc/Gcov-Intro.html)

once we're able to generate gcov reports we can run graphical tools like
lcov or gcovr
to generate html and xml reports with detailed coverage data.
an example of lcov report:
