which does not do what is intended. The operator-precedence rules of C make it equivalent to this: a = (b & (c + sizeof (int) - 1)) / sizeof (int); But what we want is this: a = ((b & c) + sizeof (int) - 1)) / sizeof (int); ...
See the precedence information in the table Precedence and Associativity of C Operators.The operands can have integral, floating, or pointer type. The types of the operands can be different. Relational operators perform the usual arithmetic conversions on integral and floating type operands. In ...
Logical Operators are used for performing logical operations , such as joining(Or,And) conditions ,negations(Not). OperatorsWhat They Do ..Precedence !It gives the complement of all values. In C , all values are Positive(Boolean 1) except 0.1 ...
