The C++ language includes all C operators and adds several new operators. Operators specify an evaluation to be performed on one or more operands. Operator precedence specifies the order of operations in expressions that contain more than one operator. Operator associativity specifies whether, in an ...
Because of this behavior, operators are said to beleft associativein Visual Basic. Overriding Precedence and Associativity You can use parentheses to force some parts of an expression to be evaluated before others. This can override both the order of precedence and the left associativity. Visual Ba...
Operators that have the same precedence are bound to their arguments in the direction of their associativity. For example, the expressiona= b= c is parsed asa=(b= c), and not as(a= b)= c because of right-to-left associativity of assignment, buta+ b- c is parsed(a+ b)- c and ...
L->R means left to right associativity. R->L means right to left associativity. You should already recognize a few of these operators, such as+,-,*,/,(), andsizeof. However, unless you have experience with another programming language, the majority of the operators in this table will ...

Expressions are constructed from operands and operators. The operators of an expression indicate which operations to apply to the operands. The order of evaluation of operators in an expression is determined by theprecedenceandassociativityof the operators. ...
Operators that are in the same cell (there may be several rows of operators listed in a cell) are evaluated with the same precedence, in the given direction. For example, the expression a=b=c is parsed as a=(b=c), and not as (a=b)=c because of right-to-left associativity. Notes...
Operator precedence is unaffected byoperator overloading. For example,std::cout<<a?b:c;parses as(std::cout<
