What is the difference between an algorithm and a program? The algorithm is a concept, the program is the concrete implementation of the algorithmThe computational thinking pattern means that everything can be seen as a mathematical problem involving numbers and formulas.Two things that any computer can do is calculate and save results.Memory: RamAlu (Arithmetic logic unit): Do some primitive operationControl unit: Track event flowStep: When reading a

Click "FileView" and select "Source Files"Then we start to create the source code file, click "File"-"new" in the upper left corner of the software, and then appear the dialog box that you just saw, select "File" in the label above, then select "C + + Source file" in the list below, file name Enter hello.c, then click " OK ".When

the outside can be multiple, we get a list, which means that sys.argv can actually be seen as a list, so we can use [] to extract the elements. The first element is the program itself, followed by the externally given parameters.Below we illustrate its usage with a very simple test.py program running results.Import SysA=SYS.ARGV[0]Print (a)Save the test.py in the root directory of the C drive.In the program, locate the ' run ', click-to-enter "cmd" and return Enter the console command window (e
