1, the design of each component module includes 3 parts: 1) Circuit Module Design 2) test Module design 3) design document preparation and collation.Among them, 2, 3 steps is particularly important. Whether the test module is rigorous and complete has set the success or failure of the system design, the complete and accurate design document for the future commissioning and maintenance brought great convenience.**************************************************************************************
Logic and ()Logic and () operations can be applied to any type of operation, not just Boolean values,The, operator does not necessarily return a Boolean value if there is an operand that is not a Boolean: follow these rules:1. If the first operand is an object (generalized), a second operand is returnedAlert (' Gecan ' NULL)//NULLAlert (' Gecan ' NaN)//NaNAlert (' Gecan ' 0)//0Alert (' Gecan ' false)//fal

Of course, there are some classic articles that will be consulted.Leave a special time to wa
If we have not participated in any formal enterprise organization training, most people may not understand how the department manager, the project manager and the technical manager are functionally different. Everyone called the manager, in fact, including the relationship between superior and subordinate and balance,

This article describes the C + + short-circuit evaluation (logic and, logic or), share for everyone to reference. The specific methods are analyzed as follows:
1, logic or short circuit
First look at the following code:

The results of the operation are as follows:
A = 1
a = 1
The logical or expressive form is as follows:
Knowledge Point: Learn to use time class and time class conversion between time format.
Requirements: 1. Execute business logic at a time of day in a thread
2. Update the time in the database table "take the time in the database and then update to the table"

Take a look at the following tests:Alert (2| | 1);The previous is true followed by true, the test result is 2, then look at one:Alert (2 | | 0)The preceding 2 is true, followed by 0 is false and the result is 2.This test feel

Thinking logic of computer programs (24) and thinking Logic
The basic types, classes, interfaces, and enumerations we introduced previously are all used to represent and operate data. There may be many errors during the operation process, and there may be many causes of errors, some are uncontrollable internal reasons, such as insufficient memory, full disk, and some are uncontrollable external reasons, suc
1. What is the difference between synchronous logic and asynchronous logic?Synchronization logic is a fixed causal relationship between clocks. Asynchronous logic does not have a fixed causal relationship between clocks.Circuit design can be categorized into synchronous circuit and asynchronous circuit design. The sync
White-box testing-logic coverage and logic coverage
White-box testing is also called structure testing, transparent box testing, logic-driven testing, or code-based testing. White box testing is a test case design method. The box refers to the tested software, and the white box refers to the visible box, you know what is inside the box and how it works. The "whit

The previous section introduced the String, and mentioned that if String modification operations are frequent, StringBuilder and StringBuffer classes should be used. The methods of these two classes are basically the same, and their implementation code is almost the same, the only difference is that StringBuffer is thread-safe, while StringBuilder is

Logic studies the structure and law of thinking forms, and studies reasoning methods. We need to study the nature of human cognition, understand the laws of knowledge generation and development, and gain great inspiration from logic.
