Today with a few classmates see a function pointer definition:void (*f (int, void (*) (int))) (int)Previously seen in the C trap pit fails inside, but the article is described in detail, but often so that beginners do not grasp the focus, the result

See http://community.csdn.net/Expert/topic/3662/3662366.xml? Temp =. 1618006 there is a post about the excitement.The specific question is what is the macro function, # define macro1 (T, m) (INT) (void *) & (T *) 0-> m ). Is to get the offset of T

Consider the following structure: Struct foo{Char c1;Short s;Char c2;Int I;};Assume that the members of this structure are in a compact arrangement in the memory. If the c1 address is 0, the s address should be 1, and the c2 address is 3, the

C language memory allocation problems 1. Memory in C is divided into four zonesSTACK: used to store the function parameters and local variables in the function. Space allocated by the compiler is automatically released by the compiler after the

Typedef struct{Uint32 numelements;Union{Uint32 objecthandle;} Entry;} Str_array, * pstr_array; These two more statements # pragma pack (push, 1)# Pragma pack (POP) # Pragma pack ([N])This command specifies the Compact alignment between the structure

Consider the following structure: struct FOO{Char C1;Short S;Char C2;int i;};Assuming that the members of this structure are in the compact in memory, assuming that the address of C1 is 0, then the address of S should be 1,C2 's address is 3,i's

Why there is memory alignmentThe following excerpt from Intel Architecture Manual.Word, double word, and four words do not need to be aligned in memory on natural boundaries. (for words, double words, and four words, the natural boundary is an even

The Primary (data) type can automatically be converted from a "smaller" type to a "larger" type. This can cause a bit of confusion when it comes to overloading. The following example shows what happens when a main type is passed to an overloaded

  The Code posted here is intended for those who need it, rather than providing the source code for others. Therefore, we apologize. This algorithm does not use a hash table as a storage container with the traditional 2D array. The advantage of this

Exception specification provides a solution to list the exceptions that a function may throw with the function declaration, so that the function does not throw any other exceptions.An exception specification violation will not be checked during

signal and slot as the core mechanism of QT is widely used in QT programming, this paper introduces some basic concepts of signal and slot, meta-object tools and some problems that should be paid attention to in the process of actual use. QT is

C/C ++ APIs for SQLite Third Edition 1.0 Overview SQLite 3.0 is a new version of SQLite. It inherits from SQLite 2.8.13, but has an incompatible file format and API. SQLite 3.0 is created based on the following requirements: UTF-16 is supported.
