The following operators have the highest precedence: (a.)* b. !c. &d. >=

Operate first, logic after (logical operator: ,=,>=,,& operation, special operation first (e.g.!) etc.) So choose B

Of the following operators in C, the one with the highest precedence is ( )A +b. += c. |d. !=

a.+ unary operator, self-incrementing operator b+= Assignment operator c

Logical operator d != Relational operator (Comparison operator:

Unary arithmetic operator -> binary arithmetic operator > relational operator -> logical operator -> assignment operator 2Therefore, the correct choice is:a

！(Non) has the highest priority.

Operator Basic Precedence:

The pointer is optimal, and monocular arithmetic is better than binocular arithmetic. Such as plus or minus signs.

Arithmetic operation first, then shift operation, last bit operation. Please note that 1 <<3 + 2 & 7 is equivalent to (1 <<3 + 2))&7Logical operations are finally combined.

I choose C,! (Non) has the highest priority.

The four options are listed in order: ! > = > If you don't understand, you can ask questions.

！(Non) has the highest priority.

a.Unary operator, self-incrementing operator. b.

Assignment operators. c.

Logical operators. d.

Relational operators (comparison operators.

Priority as specified in :

Unary arithmetic operators -> binary arithmetic operators -> relational operators -> logical operators -> assignment operators.

2.Therefore, the correct choice is:a

The lowest priority among the operators is ==.

There are several types of operators for c:

1. Arithmetic operator: * %

2. Relational operator: >== != >= <=3, logical operator: !

4. Bitwise operator: <<

5. Assignment operator: = and extended assignment operator.

6. Conditional operator: ?:

7. Comma operator: , 8. Pointer operator: * and &

9. Find the byte operator: sizeof

The answer is A

The priority of the operators of the logical anti-ABCD option from high to low is: ! Logical inverse --- remainder --& Logical and ---=assignment. Lu Taoxu.

Item C is selected for this question.

Arithmetic Operators, Logical Relationship Operators, Logical and Sum Logic, or Operators, Assignment Operators.

Only C is eligible.

C Copy provides 6 types of relational operators:

1) < (less than.

bai)2) < = (less than or equal to).

3) > (greater than).

4) > = (greater than or equal to).

Same priority (high.

du)(5) equals).

6）！Not equal to)

Same priority (low).

About the Optimal DAO Order:

1) The first 4 relational operators (<, =, >, =) have the same priority, and the last 2 are the same. The former is higher than the latter.

2) Relational operators have a lower priority than arithmetic operators.

3) Relational operators take precedence over assignment operators.

Arithmetic operators are addition, subtraction, multiplication, division, and the like, e.g. + - % (remainder), etc.

The equivalent relational operator is greater than, less than, equal to, not equal to, and with or not, for example, "= <= !".= == >

The assignment operator mainly refers to = e.g. to assign int i=1 to a variable

The priority of the operators is divided into broad categories:

Arithmetic Operations》Relational Operations》Logical Operations》Conditional Operations》Assignment Operations》Comma Operations! +

= Compound assignment.

From top to bottom, priority from highest to lowest.

Arithmetic operator +,

Relational operators ==, version! =、>、=、<、= ..

The assignment operators =, +=, -=, *=, =, %=, &=, weight=, |=、 <=、 >= ..

d non (!) It is more special, it is higher priority than with ( ) and or both, combined with and or from left to right, be sure to lay a good foundation, good luck!

The operator priorities are listed in descending order, and the correct ones are (c)%, =, &&&=.

Arithmetic Operators >> Logical & Relation Operators >> Logic & Sum Logic or DAO Operator Assignment Operator Operators are used to perform program ** operations and will perform operations on more than one operand item. For example: 2+3, the operands are 2 and 3, and the operator is "+".

1. In the logical operator, the operation priority is ( )not, and, or in order of high to low.

2. In formal logic, logical operators or logical conjunctions connect statements into more complex and complex statements. For example, suppose there are two logical propositions, "It's raining" and "I'm in the house," we can make them into complex propositions "It's raining, and I'm in the house" or "It's not raining" or "If it's raining, then I'm in the house." A new statement or proposition that combines two statements is called a compound statement or compound proposition.

The C language provides a set of logical operators: or (||and (&& non (!.)) corresponds to or, and, and not operations in propositional logic, respectively.

Logical operator: or ||In propositional logic, when p=1 or q=1, p||q is equal to 1.

Logical operator: and &&&In propositional logic, p&&q is equal to 1 when p=1 and q=1.

Logical operator: NOT !. In propositional logic, when p is equal to 0, !p is equal to 1 and vice versa.

Logical operations assume that all non-zero arguments are represented as true, while argument 0 is false, and they return either 1 (true) or 0 (false).

The logical operators &&& ||and the corresponding bit-level operations & |An important difference is that if the first parameter is evaluated to determine the result of the expression, the logical operator does not evaluate the second parameter.

For x &&y: When the logic is false with the left x, the judgment of the right y is no longer performed, and the result is false. Therefore, if a=0, the expression a &&5 a will not cause division by zero.

For x ||y: When the logic or the left x is false, continue the judgment of the right y, if it is true, the logic or the result is true; When the logic or the left x is true, the judgment of the right y is no longer performed, that is, the logic or the result is true.
