what null byte

In the php manual, "a NULL byte (& amp; quot;) is not equivalent to the NULL constant of PHP ." I don't quite understand. Where is the difference? In the php manual, "a NULL byte (" \ 0 ") is not equivalent to the NULL constant of PHP ." I don't

When reading a csv file in Python, the following error occurs: "line contains NULL byte, When _ csv. Error: line contains NULL byte occurs when python reads a file, #-*-Coding: UTF-8-*-import csvwith open (r 'e: \ abc \ web_test \ userinfo.csv ', '

The normal CSV file reads as follows:#Coding:utf-8ImportCsvcsvfilename='Demo.csv'PrintU'############### #获取某一行'with open (Csvfilename,'RB') as Csvfile:reader=Csv.reader (csvfile) rows= [row forRowinchReader]PrintRows[0], rows[1], rows[2],

(1) starting address of each member % alignment value of each member = 0. If the value is not equal to 0, the byte is null until the expression is true;(2) The overall length of a struct must be an integer multiple of its own alignment values. If it

(1) What is byte alignmentIf a variable occupies n Bytes, the start address of the variable must be divisible by N, that is, the start address % n = 0. For struct, the N value takes the Data Type of the member species as the largest space value.(2)
