g++: Display common warnings.

$ g++ ${path-to-source-cpp} -Wall -o ${path-to-output_executable}

try on your machine

This command is used to compile a C++ source file using the g++ compiler.

Here's a breakdown of the command:

g++: This is the command to invoke the g++ compiler.
${path-to-source-cpp}: This is a placeholder for the path to the C++ source file that you want to compile. You need to replace it with the actual path to your source file.
-Wall: This is a flag that enables additional warning messages during compilation. It stands for "all warnings".
-o: This is a flag that specifies the output file name for the compiled executable.
${path-to-output-executable}: This is a placeholder for the path and name of the output executable file that will be generated. You need to replace it with the actual path and name you want for your output file.

To use this command, you would replace ${path-to-source-cpp} and ${path-to-output-executable} with the appropriate values for your specific situation. For example:

g++ ~/myproject/main.cpp -Wall -o ~/myproject/myexecutable

This command would compile the main.cpp file located in the myproject directory and produce an executable named myexecutable in the same directory. Note that the ~ character represents the user's home directory.
