Because let x: y is syntactically unambiguous, but you need to know that y names a type in order to correctly parse y x. (Or at least that's the case in C where a(b) may be a variable declaration or a function call depending on what typedefs are in scope.)

POV: You open vim for the first time.

The same is true of std::endl. std::endl is simply defined as << '\n' << std::flush; nothing more, nothing less. In all cases where endl gives you a "properly translated" newline, so does \n.

std::endl provides zero portability benefits. C++ does have a portable newline abstraction, but it is called \n, not endl.

Incidentally, this is an anti-pattern: http://mywiki.wooledge.org/BashPitfalls#cmd1_.26.26_cmd2_.7C.7C_cmd3

Arguably, I never fully learned Bash syntax, but it also is just a stupid if-statement. There shouldn’t be that much complexity in it.

There isn't. The syntax is

if COMMANDthenCOMMAND(s)...elseCOMMAND(s)...fi

I believe, if you write the then onto the next line, then you don’t need the semicolon.

Yes, but that's true of all commands.

foo; bar; baz

is the same as

foobarbaz

All the ] and -z stuff has nothing to do with if. In your example, the command you're running is literally called [. You're passing it three arguments: -z, "$var", and ]. The ] argument is technically pointless but included for aesthetic reasons to match the opening ] (if you wanted to, you could also write test -z "$var" because [ is just another name for the test command).

Since you can logically negate the exit status of every command (technically, every pipeline) by prefixing a !, you could also write this as:

if ! test "$var"; then ...

The default mode of test (if given one argument) is to check whether it is non-empty.

Now, if you don't want to deal with the vagaries of the test command and do a "native" string check, that would be:

case "$var" in  "") echo "empty";;  *) echo "not empty";;esac

@affiliate Hey, you didn't even mention that char *args[] actually means char **args in a parameter list.

@stebo02 @Bogus5553 Neither of them require a return value, but void main isn't legal C++.

Strictly speaking, it should be

Unsafe block syntax in C++

{  ...}

... Perl, Haskell, Lisp, ...

https://github.com/Jaennaet/pISSStream/blob/main/pISSStream/pISSStreamApp.swift looks like code.

@hstde @Spore Even better, the alphabetical index of function names was generated in English first and then translated, meaning the documentation looks like a scrambled mess in any other language because it is alphabetized according to what the English equivalent would be. #excel
