ConstraintsIn general, when creating a database table, a data type is defined for the field, although a field is specifiedCan be stored in the data type, but it is not enough, for example, in the entry of personnel information, due to negligence forgot to fill inName field, the result is a record with no name, that is, the data in the database is contaminated, in order to avoidThe correct data is saved to the da
called multiple times. Here is a simple example of a function.
Copy Code code as follows:
1, the function is a section of JavaScript code with parameters, can be defined once, multiple calls, can also have parameters
var a = 3; Declare a variable A with a value of 3;
function fn1 (n) {///an argument is n-named fn1
return n+1; Returns a value that is greater than the value passed in
}
FN1 (a)//result is 4, because the value of a just declared a is 3, so call function, exe
changes the running status, so it is followed by a plus sign.
Each function has its own name. You can call and execute a function by name, which can be defined once and called multiple times. The following is a simple example of a function.
The Code is as follows:
// 1. A function is a JavaScript code with parameters. It can be defined at a time, called multiple times, or with parameters.Var a = 3; // declare a variable a with a value of 3;Function fn1 (n) {// a function whose parameter is
;private FragmentOne fOne;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);Log.i(TAG, "onCreate");setContentView(R.layout.activity_main);fm = getFragmentManager();fOne = (FragmentOne) fm.findFragmentById(R.id.fm_one);String fOneTag = fOne.getTag();Toast.makeText(MainActivity.this, "fOneTag:\n" + fOneTag,Toast.LENGTH_LONG).show();}}We can see that the id and tag
is a simple example of a function.Copy codeThe Code is as follows:// 1. A function is a JavaScript code with parameters.

I. Overview of standard input, standard output, error output1. Standard input (stdin) is the input of the instruction data, the code is 0, using 2. The standard output (stdout) is the result of the successful return of the instruction execution, the code is 1, the > or >> is used, and the screen is displayed by default.3. The standard error output (STDERR) is the error message returned by the instruction execution failure, the code is 2, the 2> or 2>> is used, and the default is the screen.Secon

Prerequisites:Fork () creates a process that is exactly the same as before. The execution of these two processes is not in a fixed sequence. Which process is executed first depends on the system's process scheduling policy.
After a process calls the fork () function, the system allocates resources for new processes, such as space for storing data and code. Then, all the values of the original process are

In modern web design, fonts are often used as important design elements into the web design, in a novel way to convey information. Designers have found a new way to design beautiful websites that are not dependent on images, shadows and backgrounds, and that is the design of a Web page that is based on fonts and is surprisingly effective. Today this text collects 35 good fonts as the core web design works, together to enjoy.

Because P is a block-level element, the boxes are arranged in portrait form. In practice, it is often necessary to arrange the boxes horizontally. There are two ways to achieve this. The first kind will be display:inlin-block;

, but the text content of the box will be affected by the floating element. Move to make room. In terms of the term, the line box next to the floating element is shortened so that the floating element flows out of space, so the row box surrounds the float box.2.
