How to change string a type value to complex number?
I need to perform arithmetic operations on complex numbers which are passed through command line arguments.
For example:
go run file.go 3-4i + 7+2i
Starting from Go 1.15, there is a ParseComplex function in the strconv package:

I have a long object update.PostType.RecievedFrom.Id that I need to access many times inside my program,
but I want to shorten it, so it will be more readable, by creating a variable for it id := update.PostType.RecievedFrom.Id. now my question is would this variable be a "zero overhead" variable and will be just replaced as a macro in compile time, or it does affect my program (and if it is, how can I avoid it?)
will be just replaced as a macro in compile time [?]
No.
or it does affect my program
Yes, but in a totally negligible way
(and if it is, how can I avoid it?)
You cannot and you should not bother.

I have looked through stackoverflow trying to figure this out, since I see alot of questions titled the same as mine. But I get this parse error in a Haskell file which worked perfectly the last time I opened it. I get this error-message
One defines a signature for a function by writing the name of the function, then two consecutive colons (::), and then the signature. You forgot the double colon, you thus write the signature of your concat function with:
-- ↓↓ double colon
concat :: [[a]] -> [a]

can you explain where the mistake is? when I run the program a notification appears like ORA-00936: missing expression
Insert into vemp_10_20 (employee_id,last_name,hire_date,email,job_id,salary) values ('411','Michele',to date ( '17-Sep-2010','DD-MON-RRRR'),'michele#xyz.com','MK_REP','1000');
Function is TO_DATE, not TO DATE (missing underline _).
Also, consider using YYYY format mask, not RRRR (as you specify years in 4-digits format, which is correct).

I have tried the following:
iconv('ISO-8859-1', 'UTF-8//IGNORE', 'BIG5', $input);
However, it fails and produces this error:
iconv() expects exactly 3 parameters, 4 given
Check the official documentation:
http://php.net/manual/en/function.iconv.php
You're passing an extra argument to the function.

myhash = {answer: "yes", something: hello, another: "yes"}
myhash.delete[another]
I want to delete the another key-value pair. But, ruby gives me an error saying wrong number of arguments (0 for 1). What's going on?
the method delete is a method, not an element on the hash , and another key is a symbol, so you should call on this form
myhash.delete(:another)
