The function name, function argument, and function return type uniquely determine a function.
function arguments, function return types determine a class of functions.
A pointer to a function has a type, which is the type of

When you set the path, $ java_home is used to replace the value of java_home with the location where $ java_home is located. The above statement is actually export Path =/usr/local/JDK/bin: $ path. In this statement, $ PATH also plays the same role, but the path here refers to the value of the previously set PATH variable, rather than the value of this set PATH variable.

pixel-wide black dot border with a width of 10 pixels (padding, internal whitespace) around it. Older versions of the Windows/ie browser may ignore this rule unless you specifically define the element to which this selector belongs:Example: div#sidebar {border:1px dotted #000; padding:10px;}10.

. Broadcast rules allow you to calculate on a different, but compatible, array of shapes. In other words, you don't always need to reshape or flatten the array to make their shapes match. The following example illustrates the two methods for cross product between two vectors: The first method involves the transformation of an array, and the second involves broadcasting rules. Obviously the second method is much faster.

used to create a derived selector:
# Sidebar{
Border: 1px dotted #000;
Padding: 10px;
}
According to this rule, the element with the ID of Sidebar will have a black dot border with a pixel width, and there will be a 10 pixel width padding (padding, internal blank) around it ).

Export classpath= $JAVA _home/jre/lib/rt.jar:.
The $JAVA _home used to set up PATH is the value of the replacement variable Java_home to the location of the $JAVA _home. As the last sentence is actually export path=/usr/local/jdk/bin: $PATH. $PATH is the same in this sentence, but the path here refers to the value of the path variable that was previously set, not the value of the path variable this time.

compatible with each other. In other words, you don't always need to reshape or pave the array to match their shape. The following example shows two methods for generating a vector between two vectors: the first method involves the deformation operation of the array, and the second method involves the broadcast rules. Obviously, the second method is much faster.

In the preceding example, all HTML elements with the center class are centered.In the following HTML code, both H1 and P elements have center classes. This means both of them will comply with the rules in the ". Center" selector.
Note: the first character of the class name cannot contain numbers! It does not work in Mozilla or Firefox.Like ID, class can also be used as a derivative selector:
