Algorithm block diagram teaching system

The official version of the algorithm block diagram teaching system is a convenient and easy-to-use algorithm block diagram software. The official version of the Algorithm Block Diagram Teaching System software also has built-in rich drawing tools, which can create algorithm block diagrams according to the process and set conditions, generate QBASIC program code, and save the designed flow charts in the form of files. The computer version of the algorithm block diagram teaching system can assist in the teaching of algorithm block diagrams in computer programming languages ​​and is very convenient.

Introduction to the functions of algorithm block diagram teaching system

​​ 1. The software developed by Chinese people has been packaged into a single file version by the author for the convenience of use. The "Algorithm Block Diagram Teaching System" is mainly used for the auxiliary teaching of "Chapter 2 Preliminary Algorithms" of the standard experimental textbook "Mathematics" 3 (compulsory) for ordinary high school courses.

2. Mainly used for auxiliary teaching of "Chapter 2 Preliminary Algorithms" of the standard experimental textbook "Mathematics" 3 (compulsory course) for ordinary high school courses.

3. The algorithm block diagram can be constructed arbitrarily according to teaching needs. It can run the block diagram according to the designed process and set conditions. When running, the output results will be displayed in the output window and the running process can be recorded. QBASIC program code can be generated based on the block diagram. The designed block diagram can be saved and called as a file, or as a picture for insertion into word processing systems such as Word.

​​ 4. The algorithm block diagram can be constructed arbitrarily according to teaching needs, and the block diagram can be automatically run according to the designed process and set conditions.

5. Can record the running process and output the running results. The designed flow chart can be saved and recalled in file form

Algorithm block diagram teaching system block diagram object operation

The main ones are:

The position of the moving object

Change the size (length) of an object

Copy and paste objects

Delete object

Lock object

Change the running direction of the processing box

​​Set the output box

Change the position of "Yes" and "No" of the judgment box

The above operations can be performed directly with the mouse, or by right-clicking the object, selecting "Properties", and setting relevant values ​​in the properties panel to operate the block diagram object.

Property settings include object property settings and system property settings.

Object property settings:

"Left", "Top": Set the position of the object.

"Width", "Height": Set the size of the object.

"Yes", "No": Set the "yes" and "no" positions of the judgment box.

"Input", "Output": Switching between "input box" and "output box" (when selecting the input or output box).

"Entry": the entry position when data flows from the block diagram object (the start box is "Exit"); the judgment box can choose "top" or "left", and the processing box and input/output box can choose "top" or "bottom" and "left".

“End Arrow”: Set whether there is an arrow in the process line;

"Content visible": Set whether the content in the block diagram is visible;

"Lock position": Set whether the object can be dragged by the mouse.

System property settings:

"Save decimal places": the number of decimal points in the running process and results;

"Single-step execution": Whether to execute in single step;

"Pause milliseconds": Whether to automatically pause and pause time when running to each object;

"Maximum number of loops": Set a value to prevent an infinite loop. This value is the total number of times the block diagram object is run;

“Save”: Save the current settings;

“Restore”: Restore default settings.

Contents of Algorithm Block Diagram Teaching System Block Diagram

Relevant content must be set in the input box, processing box, judgment box and output box to run the block diagram.

After double-clicking one of the above objects, the editing window will appear, as shown in the figure below:

Show content editing area

Expression editing area

Link switch

The upper part of the window is the display content editing area, and the middle part is the expression editing area. The displayed content is only for display. The system uses expressions when running, so the expression must be entered correctly. There is a link switch on the right, which is "on" by default. At this time, when the expression is modified, the displayed content will also change accordingly. In order to achieve better display effects, the display content can be pasted from Word.

The content after the exponent operator "^" is automatically displayed as a superscript; "n, 7, i" in the form: a(n), b(7), S(i), etc. is automatically displayed as a subscript.
