Dataformatstring usage notes
The syntax of the dataformatstring attribute is as follows: dataformatstring = "{0: Format String}" we know that {0} In dataformatstring represents the data itself, the format string after the colon represents the format of the data to be displayed. In addition, after the specified format symbol, you can specify the num
recorded. If the customer shows the card at each purchase, then the clerk finds the log corresponding to this card number in the store's record to add some consumption information. This approach is to maintain the status on the server side.$ C # W % t1 V $ O * o4 y' R % v"V. {3 D5 G * j! V + R, P! _ Because the HTTP protocol is stateless and does not want it to be stateful for various reasons, the next two solutions will become a realistic choice. Specifically, the cookie mechanism adopts the c
positive, and for the bidirectional iterator and the random access iterator, this value can be negative.
Use the distance () function to return the steps required to reach another iterator. Note that the distance () function is iterative, that is, it increments by the third parameter. Therefore, you must initialize this parameter. If this parameter is not initialized, it is almost doomed to fail.
Distance () Sample Code:

Similarly, these are only one character, which is very important. If you want to match a string consisting of a lowercase letter and a digit, such as "z2", "t6", or "g7 ", if it is not "ab2", "r2d3", or "b52", use this mode:

This mode matches any vowel character, but can only represent one character. The font size can be used to indicate the range of a character, for example:
[A-z] // match all lowercase letters
