$ gcov ${filename-cpp}

The command "gcov" is a tool used in code coverage analysis for C and C++ programs. It stands for "GNU coverage" and is commonly used with GCC (GNU Compiler Collection).

The command "gcov" is followed by the name of a C++ source file (filename-cpp). The ${filename-cpp} is a placeholder that should be replaced with the actual name of the C++ source file.

When executed, the "gcov" command generates coverage information for the corresponding C++ source file. It typically creates a separate file with the same name as the source file, but with a ".gcov" extension. This generated file contains details about which lines of code were executed during program execution, as well as the number of times each line was executed.

The generated coverage information can help developers identify areas of code that are not being adequately tested, allowing them to improve test coverage and potentially uncover bugs or issues.
