I. Concept of Modulo (I will only list one example. For details, refer to "same-modulus" in mathematics ")In daily life, there are many examples of subtraction and addition. For example, the clock runs at 12 bits, and can also be regarded as zero.There are two ways to adjust the hour hand from:
Ii. Use of the modulo (using the modulo to obtain the complement code)1,The following code is obtained:To convert
Verification codes are widely used in various scenarios, the random code function is added to the new user account registration, user logon, website unified login, or the user publishes an article or content in the website information module in a variety of systems or software, the verification code is used to prevent the abuse of automatically registered or published programs on the network.

Some people said that NCodeGenerate is good and has powerful functions. In the United States, the debugging function is too weak. If one-step execution is performed, you can set breakpoints and view variables, it is better to have the same debugging functions as Visual Studio. I said, "You asked too much. ". However, since NCodeGenerate uses the Razor template engine and finally generates C # code for execution, why cannot we use Visual Studio for deb
NCodeGenerate is very convenient to use.
During use, we often use some common code in different templates. If there is no extension mechanism, the code needs to be copied between various templates, which is obviously too low-level.
By the way, you are right. NCodeGenerate has a good public mechanism. There are two types in total:
I. C # code extension.
Ii. Assemb
What is a number system? Rules used to represent numeric values, such as decimal and binary.
Machine count
Represents a number in binary format. The highest digit is the sign bit. 1 indicates a negative number, and 0 indicates a positive number.
For example: 1 ----> 00000001;-1 ----> 1000 0001True Value
We can see from the above that the number of machines is a form of computer used to represent the number, but the maximum bit is a symbol. In this case, 1000 0001 represents 1 rather than 129. In
