I have four bool variables, say :
bool a=true;
bool b=false;
bool c=true;
bool d=false;
then I want to check that those four are equal. However;
Console.WriteLine(true == false == true == false);
true
Why is this happening? I think it is because of evalution order of an equation, which goes from left to right :
((true == false) == true) == false
(false == true) == false
false == false
true
then What is a proper way to check whether all N>2 boolean variables are equal?
We can evaluate values and variables using the Python bool() function. This method is used to return or convert a value to a Boolean value i.e., True or False, using the standard truth testing procedure.
In general, a Boolean variable can have only two values - True or False. Or in other words, if a variable can have only these two values, we say that it's a Boolean variable. It's often used to represent the Truth value of any given expression. Numerically, True is equal to 1 and False is equal to 0.
In Python, boolean variables are defined by the True and False keywords. The output <class 'bool'> indicates the variable is a boolean data type. Note the keywords True and False must have an Upper Case first letter. Using a lowercase true returns an error.
There are no Booleans in Bash. However, we can define the shell variable having value as 0 (“ False “) or 1 (“ True “) as per our needs. However, Bash also supports Boolean expression conditions.
if(a==b && a==c && a==d)
If you have variable number of bools not only 4
var bools = new bool[] { a, b, c, d };
var areAllEqual = bools.Skip(1).All(b=>b==bools[0]);
