How to use VSCode for writing compiler commands Simplify writing compiler commands Motivation While learning C/C++ I found that writing the compiler commands for the terminal is tedious job especially if you write many files.

With the variable $LINE_COMMENT I create a line comment, $TM_FILENAME_BASE takes the file name and $TM_FILENAME is the full file name e.g. programm.c. I included the -lpthread option as I currently study parallel programming. ...
