How do I get the opposite (negation) of a Boolean in Python?
You can just use:
boolean
What is the size of a boolean variable in Java?
It’s virtual machine dependent.
Converting bool to text in C++
How about using the C++ language itself? UPDATE: If you want more than 4 lines of code without any console output, please go to cppreference.com’s page talking about std::boolalpha and std::noboolalpha which shows you the console output and explains more about the API. Additionally using std::boolalpha will modify the global state of std::cout, you may want to restore the original behavior go here for … Read more
Is there a way to toggle a boolean variable in C#?
Yes. Use the following:
Python ‘while’ with two conditions: “and” or “or”
TLDR at bottom. First off, while loops run if the following condition is true, so must return true when simplified, for the while funtion to run The and operator returns true if both conditions are true, so the while loop will only run when it is True and True. So the following won’t run if either of the dice rolled … Read more
Logical operators for Boolean indexing in Pandas
When you say You are implicitly asking Python to convert (a[‘x’]==1) and (a[‘y’]==10) to Boolean values. NumPy arrays (of length greater than 1) and Pandas objects such as Series do not have a Boolean value — in other words, they raise ValueError: The truth value of an array is ambiguous. Use a.empty, a.any() or a.all(). when used as a … Read more
Java says this method has a constructor name
You can’t use the class name as the name for a method. The only “methods” that can share a name with the class are constructors. One fix would be to rename your class from isPalindrome to PalindromeFinder or something. That would also better align with Java naming conventions. EDIT: Note that you never actually called your method in main; … Read more
Fastest way to generate a random boolean
The first option – rand.Next(2) executes behind the scenes the following code: and for the second option – rand.NextDouble(): Since the first option contains maxValue validation, multiplication and casting, the second option is probably faster.
function does not take 1 arguments c++
You declared this at the top: So the compiler expects stringChar and stringVal functions to have no arguments. Change the declaration to:
Creating a truth table for any expression in Python
I am attempting to create a program that when run will ask for the boolean expression, the variables and then create a truth table for whatever is entered. I need to use a class and this is what I have so far. I am not sure where to go from here.
