↑The operand ofsizeofcannot be a C-style type cast: the expressionsizeof(int)*pis unambiguously interpreted as(sizeof(int))*p, but notsizeof((int)*p). ↑The expression in the middle of the conditional operator (between?and:) is parsed as if parenthesized: its precedence relative to?:is...

Use parentheses to override the defined precedence of the operators in an expression. Everything within parentheses is evaluated to yield a single value. That value can be used by any operator outside those parentheses. For example, in the expression used in the followingSETstatement, the multipli...
and logical operators. Precedence levels determine the order in which MATLAB®evaluates an expression. Within each precedence level, operators have equal precedence and are evaluated from left to right. The precedence rules for MATLAB operators are shown in this list, ordered from highest precedence...
In this case, the literals 2 and 3 are the operands, and the symbol + is the operator that tells us to apply mathematical addition on the operands to produce the new value 5. Because there is only one operator being used here, this is straightforward. In this chapter, we’ll discuss ...

val c = String::class c.supertypes.forEach { e -> println(e) } val words = listOf("car", "forest", "Bible") println(words.map(String::length)) } In the code example, we create a reference to a class and to a function with the double colon operator. ...
Operator precedence determines the order in which operators are evaluated. Operators with higher precedence are evaluated first. A common example: 3 + 4 * 5 // returns 23 The multiplication operator ("*") has higher precedence than the addition operator ("+") and thus will be evaluated first...
This is a direct result of operator precedence. Objective-C has a set of rules that tell it in which order operators should be evaluated in an expression. Clearly, Objective-C considers the multiplication operator (*) to be of a higher precedence than the addition (+) operator....
