sequentially, the other is 78 56 34 12, which is the opposite of the preceding one.Both ways can be understood. However, it is important to remember that the address of int is always low (note the premise). That is, i gets the address that is always low.So, in the first way, the address should be the space address of 78, and the second way, the address is the space address of 12!Now can continue to say the mantissa (endian), the mantissa of the 0x12345678 is naturally 78, the number of the end

Pointer to an array containing multiple function pointers:A little bit of a mouthful, this pointer points to the previous point in the "array containing multiple function pointers". 1 void (* (*P3) [2 ]) (int A, int b);　　　　　　　　　　　　　　Nothing is to replace the P2 with *p3 2 p3 = P2; The pointer must be initialized

principle:Several check codes are added to the data, and each bits of the data is assigned to several parity groups.Set: The number of check bits is R, can represent 2^r information, one means "no error", 2^r-1 to indicate the error occurred in which one.k= 2^r–1-r information can be used to correct a data bit.2^r≥k+r+1To detect and correct a single error, while discovering two errors, the R,k should meet the following relationships: 2^r-1≥k+r (see table 3.8)How the check bit and data bits are a

1. Break forces the exit loop (which can only be placed in a loop) and is used to force exit from the for statement, while statement, or repeat statement.2, continueUsed to forcibly end the loop of the call from the For statement, while statement, or repeat statement, and start the next loop.3. ExitUsed to exit from the current code block. If the code is the main program, terminate the program, or the procedure or function immediately if it is a function or procedure.4.

b1 = {p1: "p1 value", P2: "p2 value", F1: function () {alert (this. p2) }}; var b2 = new object (); b2.p2 = "B2 value"; Ext. apply (B2, B1); b2.f1 (); In the above Code, ext. the apply (B2, B1) Statement copies the attribute of B1 to the B2 object. Therefore, the message "p2 value" is displayed when you call the F1 method of B2. Although the B2 object already contains the P2 property value, the copied property value will be overwritten. You can specify the default value of the copy attribute in

file header stores information such as the size and format of the BMP image, and the color information of each pixel of the BMP image in the data area. For 24-bit real-color BMP, the size of the file header is 54 bytes. the first 14 bytes correspond to the bitmapfileinfo structure defined in VC, And the last 40 bytes correspond to the bitmapinfoheader structure. We read the data in the BMP data area and perform some operations. Then, we can use the WIN32API: stretchdibits (...) function to dire

document, both then () and catch () return a Promise, which is intriguing. (I am a newbie to js. I have never touched any previous promise in the wild ). First, the newly returned Promise is not the original Promise; Second, the status of the newly returned Promise changes (resolve (); or reject .) Keep up with the status of a Promise and the usage of then. First describe then (): (catch is similar) var p1 = Promise.resolve("Success");var p2 = p1.then(task1);var

. pointer to "array containing multiple function pointers" This title seems to be a bit closed. In short, this pointer points to the above "array containing multiple function pointers ". In fact, it is very simple. To put it bluntly, p2 in the above section is replaced by a pointer.1. Statement: void (*(*p3)[2])(int a, int b); We can see that p2 is replaced by * p3.2. assign values. Note that, since it is a pointer, it must be initialized before use:
