The tutorial first explains C #, here is a rough explanation, please purchase the relevant books, or refer to the relevant documents. C # has canceled pointers in C + +, and the number of operators used in C + + (::->) is no longer present, and C # supports a ".". C # has all the features of an object-oriented programming language, such as encapsulation, inheritance, polymorphism, and so on. And more object-oriented than Java, each type can be considered an object. But C # means to allow single

void Policy (object sender, CustomeEvetnArgs e) { System. Console. WriteLine (e. Name + "is" + e. Age. ToString ()); } } The code for associating two types of objects also needs to be modified accordingly: Employee employee = new Employee (); Employee. Name = "Mike "; Employee.

problem .) The benefits of the Android platform are still quite promising. Mike Mobile believes that "the potential of the platform benefits surprised him very much ". The general idea is that Android can get better profits by adding ads for free, such as the famous Angry Birds. However, Mike Mobile's paid application revenue is also good. Currently, the benefits of the Android platform are 80% of that of

Some basic Efficiency Improvement tips and Python3 tips for beginners in python3 Sometimes I ask myself why I don't know how to "do this" in a simpler way in Python 3. When I seek answers, over time, of course I found code that is more concise, effective, and with fewer bugs. In general (not just this article), the total number of "those" tasks exceeds what I imagined, but here is the first batch of non-obvious features, later, I found more effective/simple/maintainable code.Dictionary Keys () a

The arguments object is just like an array, and you can use an index to access its parameters.// The following function does not define parameters, but this method is still possible. function Sayhi () { alert ("Hello" +arguments[0]+arguments[1]);} Sayhi (// execution result Hello Mike GoodMorningIn the strict mode of JavaScript, the arguments object is restricted, as the follo

equal to "Mike" (the SQL command is "SELECT peopleid FROM people WHERE name = 'Mike ';"), mySQL can search for the "Mike" value in the name index, and then directly go to the corresponding row in the data file to return the peopleid (999) of the row accurately ). In this process, MySQL only needs to process one row to return results. If there is no index for the

Like Java, JavaScript is object-oriented. However, JavaScript does not have the class concept. Therefore, JavaScript constructor and Java object-oriented language constructor will be different. In Java, a common constructor can be like this: [Like Java, ja JavaScript is object-oriented. However, JavaScript does not have the class concept.
