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
