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

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 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
Raster-based data analysis has become one of the important aspects of spatial data analysis. It is widely used in site selection, planning, hydrology, and other fields. I have learned and summarized some articles by myself, and hope to share them
