The type of the expression is the type of the left. Assignment Operator in Java Example - Computer Notes An expression is a syntactic construction that has a value.

It really means that the left operand gets set to the value of the expression on the rights ( that is, " gets set to" ). In Macromedia Flash 5, the assignment operator ( = ) and the equality operator ( = = ) appear to be similar but are used for completely different reasons.

That is, the value of " $ a = 3" is 3. Old question, but regarding PHP, there is a construct you can use: $ f= $ a or $ f= $ b or $ f= $ c; / / etc.

Expressions are composed of operators and operands. C Sharp Operators and Expressions - Techotopia template derived_ type& operator= ( const xexpression& e) { temporary_ type tmp( e) ; return this- > derived_ cast( ).
Assignment operator operates on both primitive and reference types. There are quite a few of them: = * * = + = * = & = > = | | =. B = 4; / / a: 10, b: 4 a = b; / / a: 4, b: 4 b = 7; / / a: 4, b: 7 cout. An assignment operator assigns a value to its left operand based on the value of its right operand. For example, the expression x = x + 1 is equivalent to the expression x + = 1, except that the expression x is evaluated once. The evaluation of an expression produces a value, which is why expressions can appear on the right hand side of assignment statements.
