4.Both of type pointer to qualified or unqualified versions of compatible types. The resulting type is a pointer to a type qualified with all the type qualifiers of the types pointed to by both operands.
5.One operand is a pointer, and the other is a null pointer constant. The resulting type is a pointer to a type qualified with all the type qualifiers of the types pointed to by both operands.
6.One operand is a pointer to an object or incomplete type, and the other is a pointer to a qualified or unqualified version of void. The resulting type is that of the
Unlike many other programming languages, C treats value assignment as an operation (represented by an operator) rather than instruction.
Simple Assignment Operator
For a common value assignment, we use a simple assignment operator (=) :
expression1 = expression2
Expression1 is an object (memory location) to which we assign value of expression2. Operand expression1 has to be a lvalue, and expression2 can be any expression. The assignment expression itself is not an lvalue.
If expression1 and expression2 are of different types, result of the expres- sion2 will be converted to the type of expression1, if necessary. Refer to Type Conversions for more information.
Compound Assignment Operators
C allows more comlex assignments by means of compound assignment operators. Syntax of compound assignment operators is:
expression1 op= expression2
where op can be one of binary operators +,
