When I subtract a float from an integer (e.g. 1-2.0), Python does implicit type conversion (I think). But when I call what I thought was the same operation using the magic method __sub__, it suddenly does not anymore.
This question already has an answer here:I'm looking for an explanation for Java's behavior when handling the following scenarios. I understand that the ASCII table is arranged so that the value of the character 5 is five positions greater than 0. This allows for calculations to be done on the...
I am learning C++ recently and I noticed an example on cppreference, part of which goes like this:The introduction to implicit conversions tells me "when the expression is used in an if statement or a loop" the result of this expression( b2 ) will be converted into bool type implicitly.

The book The C Programming Language by Kernighan and Ritchie, second edition states on page 43 in the chapter about Type Conversions:
My code looks like this:Is there a way I could get this down to one line by somehow converting the bool Settings.adp into an int (0 or 1)
I'm trying to pick my C skills again. I want to sum a sequence in different threads, each thread would return a pointer of the sum of a part of the sequence. However, when I tried to convert the void* type value local_sum to int, problem occurred.
Before I studied the explicit keyword, my teacher said: "compiler doesn't execute consecutive user defined conversion". If it is true, are there any errors in my code? Or have I misunderstood my teacher? I'm working in VS2017.
I'm practicing Haskell by writing a program that will convert a price in cents into dollars. Obviously, this means that my Int will need to become a Double, but I want my final output to be that of a String. My code:
This question already has an answer here:I'm beginner in C. I'm trying to practice with solving some problems. And I'm getting this error when I compile my code.
