The operand of the postfix ++ and -- operators must be a modifiable lvalue that has arithmetic type.SemanticsThese operators behave like their prefix counterparts except that the value of a postfix ++ or -- expression is the value before any increment or decrement takes place....
The left operand must be an lvalue. Assignment Operator Expressions Assignment operator expressions, such as: a op= b are semantically equivalent to: a = cast(typeof(a))(a op b) except that:operand a is only evaluated once overloading op uses a different function than overloading ...

Any capture may appear only once, and its name must be different from any parameter name: struct S2 { void f(int i); }; void S2::f(int i) { [i, i] {}; // Error: i repeated [this, *this] {}; // Error: "this" repeated (C++17) [i] (int i) {}; // Error: ...
may be represented in greater precision and range than that required by the type; the types are not changed\ thereby. \begin{footnote} The cast and assignment operators must still perform their specific conversions as described in~\ref{expr.type.conv}, \ref{expr.cast}, \ref{expr.static...
If an r-value is an object (variable) it must – since C is a typed language – must have a type. The type of an expression is the type of its r-value. It’s worth having a look at some examples. In the case of an assignment expression (y = x) the result of the expression...
