Compares two characters.
1) Compares
a
and
b
for equality.
2) Compares
a
and
b
in such a way that they are totally ordered.
For the |
(since C++11) |
Parameters
a, b | - | character values to compare |
Return value
1)
true
if
a
and
b
are equal,
false
otherwise.
2)
true
if
a
is
less than
b
,
false
otherwise.
Complexity
Constant.
