Can you pass a Bool by reference?
pass-by-value issues with that boolean. I have tried passing in a ‘ref bool bFlag’ and have assigned it to a nullable bool in the client, but no avail. The variable acts like it is getting passed by value….Question.

What is Bool Swift?
Bool represents Boolean values in Swift. Swift uses only simple Boolean values in conditional contexts to help avoid accidental programming errors and to help maintain the clarity of each control statement.
Can you pass a bool by reference in C++?
By using ‘&’ you can pass it by reference. Therefore you are not copying the value of the variable into the method but the original variable with the possibility to mutate it inside the function and it will reflect the changes outside the function.
Is C# call by reference?
C# provides a ref keyword to pass argument as reference-type. It passes reference of arguments to the function rather than copy of original value. The changes in passed values are permanent and modify the original variable value.
What is NSNumber in Swift?
NSNumber is a subclass of NSValue that offers a value as any C scalar (numeric) type. It defines a set of methods specifically for setting and accessing the value as a signed or unsigned char , short int , int , long int , long long int , float , or double or as a BOOL .

How do I return a Boolean function in C++?
Boolean is a type of its own in c++, so you want the method to return bool and not int. An easy to read solution: bool Divisible(int a, int b) { int remainder = a % b; // Calculate the remainder of a and b. if(remainder == 0) { return true; //If the remainder is 0, the numbers are divisible. }
