String^ proverb;
The witness variable defined in this statement is a trace handle of type String^. When the handle is declared, it is automatically initialized to a null value, so the handle will not refer to any object. You can explicitly set it to null using the keyword nullptr:
Proverb = nullptr
Please note that you can't use 0 to represent a null value here as you do with local indicators. If the control code is initialized with 0, the value 0 will be converted into the type of the object referenced by the control code, and the address of this new object will be stored in the control code.
Initialization control codes that can also be displayed:
String^ said = L "I used to think I was indecisive, but now I'm not so sure";
This statement creates a String object on the heap containing the string to the right of the equal sign, and the address of the new object is stored in saying. Note that the type of string literal is const wchar_t*, not.
. The String class is defined in such a way that this text can be used to create objects of type String.
The editing paragraph ""is a mathematical symbol, which is used to represent three-level operation. When inputting mathematical formulas on the computer, this symbol is often used to represent the power because it is inconvenient to input the power. For example, the fifth power of 2 is usually expressed as 2 5; For example, 5 represents the square of 5, that is, the square of 5 (see power for the operation of power).
' is a bitwise logical operator.
-Bitwise Xor is a reversible operator, and the result is 1 only when the bits of two comparisons are different, otherwise the result is 0. Therefore, when calculating, we should first convert the numerical value into binary, compare the bits, and then convert the obtained result into the original decimal number. The following example: 0x03^0x05 =>；; 1 1b ^ 10 1b = 1 10b = >0x06 .
When editing this paragraph, the symbol is usually represented as the "Ctrl" key. When the key combination is displayed on the computer, the symbol is usually represented as the "Ctrl" key.
For example: f stands for ctrl+F.
Edit this paragraph. This symbol also represents the eyebrow eye expression. In the symbol of smiling face (_), this symbol represents a curved eyebrow eye.
Edit the meaning of Pascal in this paragraph 1- used to define the indicator type. Usage: pointer type = base type
2- Obtain content operators, etc.
Editing this paragraph can be used to display strict or non-strict date format in vfp database. You can use set strictdate to convert to 0/ 1.
Edit this paragraph is the bitwise XOR key of C/C++ language and C/C++. For example,101011= 010/(binary).
Edit how many powers the mathematical symbols in this paragraph represent. Because it is not easy to enter online in the formula editor, we have to use 0 instead. For example, the third power of 8 is "8 3".
The square of 23 is 23 2.
The meaning of:
1, a mathematical symbol for three-level operation. When inputting mathematical formulas on the computer, this symbol is often used to represent the power because it is inconvenient to input the power.
2. English name is Caret (English pronunciation:/? k？ r？ T/) is an inverted V morpheme. The caret (English) is a frame-shifting character called hat, control or uparrow in ASCII code point 5Ehex or other character sets.
3. It can be caret, caret, caret, caret, etc.
4. It can also represent herringbone symbols, logical XOR symbols, powers, fangs, indicators or wedges.
5. This character represents an circumflex in both ASCII and Unicode (because of its traditional role in overstrike), while caret represents another similar but lower Unicode character: "?" (caret, U+2038).
6. It is located above the number 6 in the standard keyboard and can be input by the English input method shift+6.
I. Special characters
Character: *
Chinese name: tilde, asterisk, multiplication alias: bullet hole (similar to the effect of a bullet hitting an object) Computer input method: hold down the shift key and click the number 8 on the keyboard; On the numeric keypad,------------------------. You can also press Ait first, and then press P twice.
Second, the telephone keys.
"*" is usually a pause key, which is attached to most basic pulse key phones. When the user makes an outside call, if he can't get through, use the "*" key, and then let go after hearing the public dial tone (secondary dial tone), so that the public automatic exchange can work normally. If only the "#" retransmission key is used as described above.
Third, wildcards
For example, c* stands for cadsf.wav, c 1236 1.bmp, cdsff.png and cdfjli.wsf, etc.
Fourth, the multiplication sign on the computer
In the computer, because "×" is easily confused with unknown X, it is not convenient to type, so * is used instead of multiplication sign. For example, 3*4= 12, 4*(3+6)=36 c and c++ represent indirect operators. For example, long* p stands for indicator p of type Long.
Five, mathematical code
Represents a number other than 0, for example, N* represents a positive integer.
Other functions of intransitive verbs
1 is usually used as a comment symbol.
2 is used to represent the password, reflecting the number of characters that have been entered, and at the same time preventing the entered password from being seen by others.
3 can also be used to express popular symbols on the Internet, such as *-* (halo).
It also means that some words or characters can't be displayed, or they don't meet the text review, such as sensitive words such as pornography and reaction, and are covered up.
5 is used to represent the pointer declarator in C language.
There is also the meaning of "multiplication"
What does ∑ mean? Simply put, looking for m? +m？ +m？ +...+m。
==================================
Specific explanation:
M has 1023 nonempty space sets, namely {- 1}, {0}, ... {-100}, {-10}, {-165440.
They are the so-called m? ，M？ ，M？ ...，m。
The product of all elements in each Mi is mi,
Which is M? =- 1，m？ =0，m？ = 1, ..., M 10 =- 100, ..., m =-1* 0 *1*-2 * ... *-100.

What do you mean? Sogou Pinyin, Google Pinyin and QQ Pinyin all have this symbol when you enter the word "bad", which means: bad.
What does a mean? Good books grow with me.
Books can cultivate the mind, enrich the spiritual life and broaden people's horizons. I have always been a person who loves reading, and I often travel in a boat of knowledge in the ocean of books; Riding a horse of exploration on the grassland of books. Since childhood, books have always been my faithful companion and close friend. From Ouyang Xiu to Cao Xueqin, from Lu Xun to Ba Jin, from astronomical geography to celebrity anecdotes, from the Four Books and Five Classics to science fiction reasoning, there are traces I have read everywhere.
Romance of the Three Kingdoms and The Journey to the West were my favorite books in primary school. Maybe every boy has a dream of commanding thousands of troops or killing demons, but my dream can only be realized in books. Sometimes I have to dress up as Zhu Gekongming, talk with feather fans, black scarves and Confucian scholars; Or chanting and holding a sword, skillfully borrowing the east wind, dripping freely; There are also fashions like the Monkey King's bonzi, which shocked the mountain and shocked the tiger to go to the Heavenly Palace, or flew underground for 72 years. These two books let me know the strategic wisdom and the chivalrous spirit of giving up one's life for righteousness. They taught me the philosophy of being a man and the skills of doing things, which benefited me a lot.
When I was in junior high school, I preferred reading foreign classics. Among them, I admire Mark Twain, the master of humor, and Conan Doyle, the father of reasoning. If Conan Doyle portrayed Sherlock Holmes as a detective model, then Mark Twain portrayed an out-and-out urchin image-tom sawyer. In addition, Niels' Adventures of Goose Riding, Pinocchio's Adventures and Peter Pan's Dumbo conquered me with their wild imaginations. The gifts of the Magi and Shakespeare's tragedies and comedies deeply shocked my soul.
How I want to be as talented and eye-catching as Sherlock Holmes; I also want to be as free as tom sawyer. I am more eager to be as adventurous and happy as Niels Huo Jiasi. The time spent with the characters in the book is the most unforgettable.
A good book, like a person in the spring breeze, a person in the summer rain and rain, makes people clear-headed. Its value lies in that everyone loves reading, and a person who can read should treat every book like a good friend, even if advice is most unpleasant.
Good books grow with me. In my life, a good book is like a relative, a good book is like a bosom friend, and a good book is like a mentor. Shape my character, promote good and discard evil; Guide my direction, distinguish right from wrong, it is these that help me climb to new heights! Thank you!
