month, the price should be in what paragraph. Suddenly its price is very low, the system thinks this time is more suitable for purchase. Is the price very low when must buy? You'll have to watch your inventory. The same is true for sales, and we've already estimated that this product will have a big gain by September, and it's going to have a big gain by September. This year also should have, even if it is not up to the highest, according to the year, the first annual increase of 2%, the second
The reason why the wild pointer is produced:1, the pointer variable and the memory space variable that he points to are two different concepts2, although the call to the free (p) method frees the memory space pointed to by the pointer, but the pointer variable is not reset to null3, resulting in the freed of the pointed memory space, the use if (p! = NULL) is also executed, and the free () method is executedAvoidance methods:1, when the pointer is defined, initializes its value to null (char *p
The function of the application memory space in the C language malloc ()char *p = NULL;p = (char *) malloc (sizeof (char) * 100);The meaning of the above code is:Defines a char-type pointer pAllocate size to the memory space pointed by the pointer p through the MALLOC functionP is the memory addresssizeof is the number of bytes occupied by getting char, typically 4 bytesThe malloc function is the void* function (void * __cdecl malloc (_in_ _crt_guardoverflow size_t _size);)So to force the defini
code in the red area? It's not a good idea. Do you not know which object to pass in? What's the new object? Then consulted the developer sitting next to my colleague, finally figured out that the reflection is not so used, the above code can not be used to write the reflection code. The real reflection usage is this:Class Clazz=class.forname ("Com.learn.reflect.Person");--first or load the target classObject obj=clazz.newinstence;Method M=clazz.getmethod ("Print3", String[].class); --string[].c

The static keyword in the OC syntax cannot be decorated with attributes, nor can it be decorated with methods, only local variables in the method. Static modifies a local variable and then changes the local variable to a static variable. This variable is not recycled when the method is executed. This variable is still in place the next time you execute this method.Self is a pointer, and in the object method, self points to the current object. Therefore, you can use self to explicitly access the
