Basic arithmetic operatorsIn this chapter, we mainly introduce arithmetic operators and arithmetic expressions, assignment operators and assignment expressions, comma and comma expressions, and other operators will be introduced in later chapters.
Order of precedence between 4.1.6 operatorsIn the expression of some more complex conditional judgments, in the same expression, sometimes there may be multiple operators. For example, we judge whether to buy a watermelon, not only to determine its

An operator is a symbol that tells the compiler to perform a specific mathematical or logical operation. C + + has a rich operator built into it and provides the following types of operators:
Arithmetic operators
Relational operators
Today went over the C language operators of the priority and binding, found that the original learning time did not seriously remember, ashamed. Found a well-spoken article, edited the next turn for later browsing.C language operator precedence
When you operate in each expression, each part of the operation is evaluated in a certain order, which is the order of precedence of the operation, also called the precedence of the operator.
In an expression, if there is more than one operator,
The operator precedence specifies how tightly the two expressions are bound. For example, the result of an expression 1 + 5 * 3 is 16 instead of 18 because multiplication sign ("*") has a higher precedence than a plus sign ("+"). You can use
The operator precedence specifies how tightly the two expressions are bound. For example, the result of the expression 1 + 5 * 3 is that it is because multiplication sign ("*") has a higher priority than the plus sign ("+"). You can use
In C #, there are 38 commonly used characters, based on the characteristics of the operations they perform and their precedence, and for ease of memory, I classify them as seven levels: 1, cell operators, and parentheses. 2. Regular arithmetic
Recently, because of the source code in the reading Underscore.js, plus the IFE before the completion of the JavaScript part of the Task2, which a large number of abbreviated sentence wording, especially like?: This trinocular operator is combined
