order of arithmetic operations

1. arithmetic operation points (1) shift operation ① Original code shift: the original code does not change the form of the original code when performing arithmetic shift left or arithmetic shift right. Shifts one digit to the left is equal to

(Part 2) 5. Implementation of top-down syntax analysis programs After four steps of careful preparation, the most exciting time has come. Generally, most of the Code in the textbook "compilation principles" is pseudo code that cannot be run on a

The variables in the shell are stored as strings, even if you assign values to the value of the shape unless you declare the variable by declare-i. In the case of numerical/arithmetic operations, you may find the following $ x=121$ echo $x

The Calculation of arithmetic expressions in a computer is implemented through stacks. This section first discusses two Representation Methods of arithmetic expressions, namely, the infix representation and the suffix representation. Then, it

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.

The content of this section is a bit dull, but very simple, remember, just like in elementary school we just learned subtraction mixed operation. Remember the priority of the operation. (Of course, if you have a C language or other basis, you can

1. Implicit conversion c is implicitly converted in the following four scenarios: 1, in arithmetic expressions, the low type can be converted to a high type. 2 . In an assignment expression, the value of the right expression is automatically

Four arithmetic operations, of course, the most commonly used method is the inverse Polish method. Now the expression is converted from an infix expression to a suffix expression, and then it can be computed using the stack. In these two steps, it

C language bit operationA bitwise operation is a binary-based operation. In system software, it is often necessary to deal with bits problems. The C language provides 6 bit manipulation operators. These operators can only be used for integer
