The Boolean variable type is probably the easiest type of variable. It doesn’t have a “maximum range”, it can’t produce “overflow” exceptions, it’s not affected by precision, etc. In fact, Boolean variable type can only have two values: true or false. They are almost exclusively used for calculations of logical expressions. They are declared using the keyword bool.
Here is a short example where we can use Boolean variables:
int a = 1;
int b = 2;
// Which one is greater?
bool greaterAB = (a > b);
Console.WriteLine("a is greater than b = " + greaterAB);
Console.Read();
When compiled and ran, the program will display the following output:
