$ gcov --branch-counts ${filename-cpp}

try on your machine

The command "gcov --branch-counts ${filename-cpp}" is used to generate code coverage information for a C++ program using the Gcov tool.

Gcov is a coverage profiling tool that is typically used along with the GNU Compiler Collection (GCC). It allows you to determine which parts of your code are being executed and how many times, providing valuable insights into possible areas for improvement or optimization.

In this specific command, the "--branch-counts" option is used to collect information about branch decisions in the program. It enables the collection of branch counts, which can reveal how often each branch of a conditional statement is taken during program execution.

The "${filename-cpp}" placeholder is used to represent the name of the C++ source file that you want to analyze with Gcov. You need to replace this placeholder with the actual file name or path to the file in the command.

When this command is executed, Gcov will generate a coverage report for the specified C++ file, displaying the number of times each branch has been taken. This information can be used for analysis, optimization, or debugging purposes to assess the effectiveness and completeness of your tests.
