Arithmetic refinement:1, avoid repeating first first question A1, B1 and C1 (subtraction) are randomly generated, and then the second question A2, B2 and C2 (subtraction) also randomly generated and judged A2, B2, C2 and A1, B1, C1 is exactly the same, if the exact same regeneration, third, IV, fifth are the same.2, can be customized (quantity/printing) input a data E, when the generation of e-computing problems, go to the next page.3, the following parameters can be controlled: whether there is

the work, and then introduce this method second: only when a control is rendered to the interface will we put it in a static dictionary, This is the line of code: RENDERCONTEXT.CONTROLDIC.ADD (CTL. Id, CTL); third: For a container control, he has a children collection that is used to store his own child controls, which is the line of code: this. Children.add (CTL); Six: Tojs Method of Button In this method, we get the JS script of the binding event and

Some casual ideas about the design philosophy of the C ++ language system (to be continued)For a static language, its essential goal is to properly operate the data and obtain the expected value. Specifically, you need to: (1) define the data type, whether it is integer, floating point, or character. What is the range of values that can be included in data of this type. (2) define the meaning of an operatio

1. Obtain related requirements for the question, such as the question quantity, multiplication and division settings, value range settings, addition and subtraction with or without negative numbers, Division with or without remainder, and whether scores are supported.2. Based on the obtained value range, use the corresponding number of cycles to obtain the question.3. each cycle needs to implement the previously obtained question requirements. First, check whether scores are supported and whethe

to control. 4, the following parameters can be controlled (I simplify the block according to my own idea): Set the options in the General program framework, the initial implementation of the problem is implemented in its options, is equivalent to a piece of paper on the block. A piece of the problem only this piece of this kind of problem. The student chooses which option to do that piece of question.
