Awk string functions (2)
The substr function returns a substring starting from the specified position of the string. If the length of the substring is specified, the corresponding part of the string is returned. If the specified length exceeds the actual range of the string, the actual content is returned.FormatSubstr (string, starting position)
Substr (string, starting position, substring length)

adChar, and 1 is the input parameter (in fact, it is the default value)
For details, refer to MICROSOFT's ADOVB. Inc:
The Code is as follows:
'---- ParameterDirectionEnum Values ----
Const adParamUnknown = 0
Const adParamInput = 1
Const adParamOutput = 2
Const adParamInputOutput = 3
Const adParamReturnValue = 4

, MySQL returns 0 if you do not use 2 or 3 as an optional parameter:Mysql> Select Year ('2014-01-01 '), Week ('2014-01-01', 0 );-> 2000, 0Mysql> select Week ('2017-01-01 ', 2 );-> 52
You may argue that when the given date value is actually part of Week 1999 of 52nd, MySQL should return 52 for the week () function. We
comparison is done through a user-supplied callback function. If you think that the first parameter is less than, equal to, or greater than the second argument, you must return an integer less than 0, equal to zero, or greater than 0, respectively.8. The Array_fill () function fills the array with key values.Array_fill (index,number,value);The Array_fill () function populates the array with the given value

The js used in discuz is very good in compatibility and practicability of multiple browsers. We recommend you read var lang = new Array ();
Var userAgent = navigator. userAgent. toLowerCase ();
Var is_opera = userAgent. indexOf ('Opera ')! =-1 opera. version ();
Var is_moz = (navigator. product = 'gecko ') userAgent. substr (userAgent. indexOf ('Firefox') + 8, 3 );
Var is_ie = (userAgent. indexOf ('msie ')! =-1 ! Is_opera) userAgent. substr (userAgent. indexOf ('msie ') + 5, 3 );

Add some common PHP functions to the favorites page. Copy the code as follows :? FunctionGetIP () {get IPif ($ _ SERVER [HTTP_X_FORWARDED_FOR]) $ ip $ _ SERVER [HTTP_X_FORWARDED_FOR]; elseif ($ _ SERVER [HTTP_CLIENT_IP]) $ ip
The code is as follows:
Function GetIP () {// obtain the IP addressIf ($ _ SERVER ["HTTP_X_FORWARDED_FOR"])$ Ip = $ _ SERVER ["HTTP_X_FORWARDED_FOR"];Else if ($ _ SERVER ["HTTP_CLIENT_IP"])$ Ip = $ _ SERVER ["HTTP_CLIENT_IP"

criticized by C ++. It uses C ++-considered unsafe type conversion, insecure void * pointer, and so on. However, this is The Calling Interface left by the system for the C language. So how can we call the member function pointer in the C ++ program?For example, we plan to call the specified member functions for all classes in the vector:# Include # Include # Include # Include Using namespace STD;
Class{Int value;Public:A (INT v) {value = V ;}Void do
