Call conventions:_ Cdecl _ fastcall and _ stdcall are call conventions (calling convention), which determine the following content: 1) the order of function parameters in the pressure stack; 2) the parameter pop-up stack is made by the caller or the caller. 3) the method for generating the function modifier name.1. _ stdcall call Convention: The function parameters are passed from right to left through the stack. The called function clears the memory
Recent review of learn objective-C on the Mac In Chapter 4th, [Super setfillcolor: C] is called for rewriting. It may be because the translation logic is unclear. I wrote a small example to understand it. Define a father class and son class Father: #import #import "father.h"@implementation father-(void)setNum:(int)c{ num =

Call by is a standard term in computer science. Method calls are divided into call by reference and call by value based on the passing of parameters ). There are many definitions of these two types of calls. The most common saying is that the value is passed, and the address is the reference call. This is not appropriate. These statements can easily remind us that the object parameter passing in Java is a reference call. In fact, the object parameter

memory leakage, frequent allocation and release of heap space of different sizes will generate fragments in the heap. 2. program memory space A program divides the memory blocks allocated to the operating system into four areas, as shown in. Code area (Code area) program memory space Data Area) Heap Area) Stack Area) The memory occupied by a C/C ++ compiled program is divided into the following parts, 1.
C # Digital Image processing Algorithm learning Note (i) the 3 method of--c# image processingBitmap class: This class encapsulates a bitmap in GDI +, which consists of pixel data for a graphical image and its properties. Therefore, this class is an object used to manipulate the graphics of the pixel data definition. The main methods and properties of this class a
?First we have to understand that we have to determine the precision of "root", that is, the value of the ANS of the F (ANS) =0 is not less than 1e-4, we do not know what the value of the truth is, but we can confirm his function value, that is, 0, So this problem translates into the value that we can calculate ans the value of the function f (ans) and 0 of the absolute difference is not greater than 1e-4, so we could find the current mid is the possible midpoint of the value, see if he and 0 i

If there is, compile through, if no compilation fails.② at run time: see if there are methods called in the class to which the object belongs.③ Simple Summary is: Member method in polymorphic call, compile look to the left, run look to the right.6) in polymorphism, the characteristics of member variables: both compile and run, refer to the left (the class to which the reference variable belongs).7) in p

is equal to the first two months the sum of the large rabbit logarithm. If the N-month large rabbit logarithm is expressed in un, there isUN = un-1 + un-2, n >2 each month the number of large rabbits in the series is: 1,1,2,3,5,8,13,21,34,55,89,144, /c5> this sequence is called the Fibonacci sequence.

C ++ select the sorting method and select the sorting method Select sort: A group of unordered data a [1], a [2], and a [n] are known. If they are listed in ascending order. First, compare the values of a [1] and a [2]. If a [1] is greater than a [2], the values of the two are exchanged. Otherwise, the values remain unchanged. Compare the values of a [1] and a [3

across layers. But the difference is that the API is the lower level of the call to the upper layer, generally this function is known to the upper level, and the reverse is the opposite, he is the upper level to provide to the bottom of the call , for the lower layer he is unknown, must be installed by the high-level, This installation function is actually a low-level API, the post-installation low-level does not know the name of the callback, but it through a function pointer to save the callb
