a C comment trick
Today I saw a trick to comment and uncomment multiple lines of code in C. It
// to comment as below:
/* foo(); bar(); //*/
To uncomment, just add another
/ in the first line:
//* foo(); bar(); //*/
So you don’t need to change the other end, which saves a lot of time.
// is not ANSI C and is brought in by C++, actually many
compilers support this format of comments.
