A few simple digital problems have caused a simple reflection on the computer logic. New posts, experts do not Brick ., Logic Some time ago, before learning how to determine whether a number is a prime number or whether a number is an odd number, I did not think about how computers are implemented. I think the reason is that the thinking of the human brain is very different from the

Most of the current frameworks are in the MVC mode, but here is a summary of how MVC works:Basic principle: business logicCodeIt should be written in M and appliedProgramThe logic should be written in C. V is just a simple display of data.For example, you can add a commodity to the shopping cart.The user clicks the "add to shopping cart" button to send a request. The server starts to process the request. The process is as follows:1. Check whether the

Logical Operation: Can judge whether two or more conditions are established, from three kinds; Logic, logic, logic, or the result is 1 and 0; true and false; Logic and condition a condition B; only A and b result is 1 when it is 1; || logical OR; When a or b is established, the result is 1; none i

In other languages, we often see logical symbols appearing in judgment statements, such asif (a| | b) {}But in some JS-related questions or books, we sometimes see logic with and logic or | | The symbol appears in an assignment statement or in a return statement, such asvar x=a| | b; Return ab| | CThe first time we saw it, we were probably confused, what's going on?Because the expression is allowed to be a

Logic or (|) operations in js and logic operations in js The logic or: | is used in js. The following describes its usage: 1. If there is a Boolean value of true, true is returned.2. If it is not a Boolean value: A. if the first operand is an object, the first operand is returned; B. If the evaluate result of the first operand is false, the second operand is

two-direction read. Understanding the application of binary, we put forward the logic, logic is proposed by Socrates, the most famous is the three-paragraph theory. Next is the Boolean algebra proposed by the Boolean, his breakthrough is that compared to the traditional algebra, he is the operand of the abstract, so that the operand represents a class, Boolean algebra includes: And, or, not, 1, 0. We can a

Thinking logic of computer programs (5), thinking Logic Intuitive fact violations The reason why a computer is called a "computing" machine is because it was invented mainly for computing. "computing" is of course its specialty. In everyone's impression, computing must be very accurate. But in fact, even in some basic decimal operations, the calculation results are not accurate. For example: float f = 0.1f*

Thinking logic of computer programs (14), thinking Logic It is said that Tao shengyi has a second, second, and third life. If binary representation and operation are regarded as one, the basic data type is regarded as two, and the basic data type is regarded as three, then, the combination of classes and the inheritance introduced in the next section make the three born things. In the previous section, we i

Thinking logic of computer programs (13), thinking Logic Class In the previous section, we introduced the basic principles of function calling. In this section and the next sections, we will explore the world of classes. Programs mainly involve data and operations on data. To facilitate understanding and operation, advanced languages use the data type concept. Different data types have different features an
