Does true equal to 1 and false equal to 0? [duplicate]
I was wondering, does true
equal to 1 and false
equal to 0 and how?
false == 0
and true = !false
. I.e. anything that is not zero and can be converted to a boolean is not false
, thus it must be true
. Some examples to clarify:
if(0) // false
if(1) // true
if(2) // true
if(0 == false) // true
if(0 == true) // false
if(1 == false) // false
if(1 == true) // true
if(2 == false) // false
if(2 == true) // false
cout << false // 0
cout << true // 1
true
is equal to 1
, but any non-zero int
evaluates to true
but is not equal to true
except 1
.
Yes that is correct. "Boolean variables only have two possible values: true (1) and false (0)." cpp tutorial on boolean values
