Operators associate with either the expression on their left or the expression on their right; this is called "associativity." The following table shows the precedence and associativity of C++ operators (from highest to lowest precedence). Operators in the same segment of the table have equal ...
Operator precedence is unaffected byoperator overloading. For example,std::cout<<a?b:c;parses as(std::cout<
In most cases, the order of evaluation for operands and function arguments is unspecified, meaning they may be evaluated in any order. Consider the following expression: a*b+c*d We know from the precedence and associativity rules above that this expression will be grouped as if we had typed...

b is multiplied by c before it is divided by d because of associativity.The following tables list the C and C++ language operators in order of precedence and show the direction of associativity for each operator. Operators that have the same rank have the same precedence....
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...
Example 1 of C++ Operator Precedence: Expression: 4 / 2 * 3 - 1 In this expression, multiplication and division have the same precedence order. Therefore, we will evaluate them from left to right, according to their associativity rule, which is left-to-right for both multiplication and divis...

Visual Basic always performs operations that are enclosed in parentheses before those outside. However, within parentheses, it maintains ordinary precedence and associativity, unless you use parentheses within the parentheses. The following example illustrates this. VB Copy Dim a, b, c, d, e, f...
Swift Operator Associativity If an expression has two operators with similar precedence, the expression is evaluated according to its associativity (either left to right, or right to left). For example, print(6 * 4 / 3) // 8 Here, operators * and / have the same precedence. And, their...
