a string into multiple substrings of equal length. The syntax format for the Str_split () function is as follows: Array str_split (string $string [, int $split _length=1]) The arguments in the above syntax are described as follows: string: Specifies the string to be split, Split_length: Specifies the length of each array element, and the default value is "1".

stupid), and 1729, (x + y), std::string ("Me Ow "), and x++ is not legal. Why does this approach work? Because the fetch operation requires its "operand must be a lvalue" (see C + + 03 5.3.1/2). Why should there be such a rule? Because it's okay to access a persistent object, however, it is extremely dangerous to address a temporary object because the temporary object will soon be destroyed (as you have a pointer to an object that is released, but y
Before talking about function call and return value problem, let's look at the problem of memory allocation in C + +.
The C + + compiler divides computer memory into code areas and data areas, and it is clear that the code area is where the program code is stored, and the data area is the variables and constants that appear in the process of compiling and executing the program. The data area is divided into static data area, Dynamic Data area an

convenient to implement using the generator, instead of implementing the five methods in the iterator interface.The generator is an interrupted function.It is very important to understand the collaboration program from the generator and how they work internally: the generator is an interrupt function, in which yield forms a breakpoint.
In the preceding example, if you call xrange (), the code in the xrange () function does not actually run. On the co
, transaction 1 allows reading uncommitted data, while transaction 2 allows reading only committed data.
In the main program, we simulate different operations of two people to generate concurrency consistency problems:
