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 |

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.
