Let's just give an example.A 1-byte number 7 is represented by a binary representation of 0000 0111, the highest bit is 0 (0 is positive, and 1 is negative)The inverse code is the inverse of all the digits of a positive number, including the highest

The following is an overview of what you can say in plain words: Pointers-For a type t,t* is a pointer to T type, that is, a variable of type t* can hold the address of a T object, and type T can add some qualifiers, such as const, volatile

Transformations and inheritanceThis section mainly needs to distinguish between: Conversion of base classes and derived classes; Conversions of references (pointers) and conversions of objects. 1. Each derived class object includes

The sixth chapter of the book is segregated. What needs to be defined in the header file primarily in pose? What should be moved to the compilation unit?The core is still to differentiate between the interface definition and implementation details

//1. Set the form's property keyprieview to True//when the KeyPreview property is true, it can respond to keyboard events v//2. Add the following code to the form KeyDown eventPrivate voidForm1_keydown (Objectsender, KeyEventArgs e) {

In the above mentioned SortedList sort is the key sort, does not conform to the project requirement problem, then uses the dictionary dictionary to the value for the time in ascending order, the problem solves.The middle involves the use of LINQ.

One, file streamThe FileStream class is primarily used to read and write disk files. Often used to store data or read configuration files to disk.Read file:Copy Code//file stream: ReadFileStream FileStream = File.Open (@"D:\test.txt", FileMode.Open);

Reason:Because the long type is System.Int64 (Long integer, which accounts for 8 bytes, representing 64-bit integers, the range is approximately-(10 of 19) to 10 of the square)The Long Binaryreader.readint64 () method reads a eight-byte signed
