gcov:tldr:5bf2c

The "gcov" command is used for generating code coverage information for C and C++ programs. Here's an explanation of the provided command:

• "gcov": This is the actual command that runs the coverage analysis.
• "--no-output": It is an option that tells gcov to not produce any output files. By default, gcov generates several output files containing coverage information for each source file being analyzed. However, with this option, no output files will be created, and the command will only display the coverage statistics on the terminal.
• "${filename-cpp}": This is a placeholder for the name of the C++ source file you want to analyze. You need to replace "${filename-cpp}" with the actual name of the file you want to analyze, including the ".cpp" extension.

To use this command, you would replace "${filename-cpp}" with the desired C++ file name and run it to get coverage statistics without generating any output files.
