Unary Minus Operator( Negation)
This operand can be used to negate the value of a variable. It is also used to state a negative number, here a minus(-) sign is prefixed to the number.
e.g.
int x = 5;
int z = -10;
y = -x;
a = z;
The value of y now becomes -5 and 'a' becomes -10.
Though, the language does not offer any unary + operator
