onshift 1234

^3 = 8192-------------------------------------10997 Now you can see that all of the conversion into 10, the key is the different weight values. Suppose someone asks you, ten to 1234 why is 1234. You can give him such a formula: 1234 = 1 * 10^3 + 2 * 10^2 + 3 * 10^1 + 4 * 10^0 Two, Hex converts to each other First we look at a binary number: 1111, how much is it?

it's impossible to truly predict the future, it is possible to write code that's flexible enough to be reasonably future proof. Saner Parameter ListsOne place where future-proofing can be done is when designing parameter lists. they're the main point of contact for people implementing your code and can be problematic if not well designed. what you want to avoid are parameter lists like this: The Code is as follows: Function Person (employeeId, fname, lname, tel, fax, email, email2, dob ){}

balancer) only involve the data layer. Strictly speaking, for a well-designed system, only one function of a class is involved: In the data layer, a connection class is generally divided separately, in addition, there is a connection function in this connection class, which needs to be changed: add a function before reading the connection string to return the required host, ip address, port number, and other information. (It may be difficult for developers to understand this section ). The flow

If the first character of S is a letter, the first letter of the copy is converted to uppercase, and all the remaining letters are converted to lowercase.For example:>>> ' This is a test string. '.
