What should A and C do? What is the difference between C and A

It's so long, I can't understand my English if I don't understand it Haha, just kidding, what to do depends on a yourself, don't forget that you are a person with a family Your own life, act it yourself.

Oh, I can't stand it after reading the first three lines. You're C, aren't you? If you are C, it is recommended that you leave A, and if you are A, it is recommended that you marry C. If you're nobody, it's recommended that you don't do anything ......Quite simply, one can be selfish all his life, but not for a while.

Kind and cowardly people tend to choose to give up, and C is. And if A really loves, then he loves C so much, and he won't be afraid of hurting B. In fact, A loves C so much that he is hurting B, and it is better to let B find his true destiny in his illness after a short pain than to hurt more deeply in the future.

It is A's actions that cause the tragedy of B and C.

A works hard to make money, gives B a child, gives money to C

I think that A should tell the truth, who A likes, not this and that, after saying his heart, he should love that person wholeheartedly!

Is the questioner C? A or B okay.

The most essential difference between C (combination) and A (arrangement) is whether the elements taken out are ordered or there are order requirements. A is the so-called arrangement, which refers to taking a specified number of elements from a given number of elements and sorting them. c means that only a specified number of elements are taken from a given number of elements, regardless of sorting.

Definition of arrangement: from n different elements, any m (m n, m and n are natural numbers, the same below) elements are arranged in a certain order, which is called taking out an arrangement of m elements from n different elements; The number of all permutations of m (m n) elements from n different elements is called the number of permutations of m elements from n different elements, which is represented by the symbol a(n, m).

Definition of combination: from n different elements, any m (m n) elements are taken into a group, which is called a combination of m elements from n different elements; The number of all combinations of m (m n) elements taken out of n different elements is called the number of combinations of m elements taken out of n different elements. It is represented by the symbol c(n,m).

In probability,"c"On behalf of the combination of file staring,"a"Representative permutation. There are some differences in how they are calculated.

1.Combination (c): Composition refers to the way in which several objects are selected from a group of objects, regardless of their order. Combinations are used to count the number of selected object collections. In composition, the order of the elements is not important.

It is calculated as c(n, k) = n! /k! *n - k)!)

where n is the total number of objects and k is the number of objects to be selected"!Represents a factorial.

2.Permutation (a): Permutation refers to the way in which several objects are selected from a group of objects and arranged in a specific order. Permutations are used for row bends and the number of different permutations of the calculated object. In arrangement, the order of the elements is important.

Calculation formula: a(n, k) = n! /n - k)!

where n is the total number of objects and k is the number of objects to be selected"!Represents a factorial.

To sum up, the combination is suitable for the noisy person to select the number of objects regardless of the order, while the arrangement is suitable for the case of selecting objects and arranging them in a specific order.

There are two more credible theories, one is that the tone name was used by the British, and the Irish music has many minor keys, and the main tone is la, so they gave the sound name A to la, so that do is c; The second is that the absolute pitch of the sound name was determined by the ** family and physicists in the 19th century, and the benchmark is the treble A (440Hz), that is, the empty string of the violin A string. All other sound names are calculated according to the law of twelve equals. There is also a saying that the first key on the left side of the piano is A, and the first statement contains too many historical factors, see if it can be verified; In the second case, what the hell is 440hz?

How did it come about? There is an idea when I look at the answer to the sticker.,In fact, it started from A (such as the starting key of the piano),The reason why there is the illusion of starting from C is because I have been learning C major since I started learning the piano.,Because C major is all white keys and perfectly matches the key of major.,In fact, A-G has its own major and minor keys.,Each key has its own DO.,From A3 onwards, you can also play DO,RE,MI,FA,SOL,LA,SI,DO,but C major is the most basic and natural key., And it is used the most, so it is mainly practiced at the beginning of the school. And the reason why it's called **c is because it's really the middle key of the piano (88-key piano, it's the 40th, with three octaves in front and three octaves in the back).

-aExecute A-1 before A-- Execute A-- Execute a-1 after A-1

Answer: C Explanation: Who do you think is the richest man

In this sentence, who is the subject and uses the nominative form, while whom is the accusative form and cannot act as the subject of the sentence, so the answer A is wrong.

I wish you a happy new year and take your studies to the next level! Please remember, thank you! (*

c is the correct answer.

Because from this sentence it is necessary to have a sentence backbone. Sentence stems generally require the subject-predicate part. This sentence is a special interrogative sentence and not a general interrogative sentence, so B cannot be selected, and the question word that can be the subject can only be who, so A cannot be selected, and do you think is actually an insertion in this sentence, in addition, because the sentence is a question sentence, it is used to do you think instead of you think.

When a person is called an object, whom is used

Use who to ask questions as a subject

WHOM is generally not used as a special interrogative word for personal questions, because who is the accusative form of who, so whom is mostly used as an object in the sentence, and do you think in this question is an interpolation, which can be completely ignored. If you ask Jim in Jim is the Richest Man in this Town, the question would be Who is the Richest Man in this Town? Because this is a question of the subject of the original sentence.

So choose C for this question

A is potassium chlorate in the source dust, white powder, C is potassium chloride, which is formed by the catalytic action of manganese oxide in the black solid E two banquets, and its cracking is also oxygen

Because you have one in the middle of your input; So in the first argument of scanf to add;

Format of the first parameter:

The format string consists of the following.

Non-whitespace multi-byte characters, except for % of each format string This character is processed from the input stream exactly, or if it is not equal to the next character in the stream it causes the function to fail.

Whitespace: A single whitespace in any formatted string handles all available consecutive whitespaces from the input (as determined by calling isspace in a loop). Note the format in the string"" 、 " " 、 "\t\t"or other blanks.

Conversion Assignments: Each transformation assignment has the following formats:

Introduce the % character.

Optional) Assign Suppression Character * If this option is present, this function does not assign the result to any receiving parameters.

Optional) specifies the integer number (greater than zero) with the maximum domain width, that is, the maximum number of characters that the function is allowed to process when the current transformation specifies the specified transformation. NoteIf the width is not provided, %s and %[ may cause the buffer to overflow.

Optional) specifies the length modifier of the received parameter size, which is the actual target type. This affects conversion accuracy and overflow rules. The default target type is different for each conversion type.

The phase sequence of the system side is a, b, c, and the phase sequence of the generator side is a, b, and c can be parallel in the same phase, assuming that a a is the same phase sequence at this time, the line voltage is 0, and the power supply delivered by the same generator is the same, so the frequency is the same. So it can be juxtaposed.

If the phase A B or C is different, the line voltage is actually the power supply voltage), the equipment switch trips, and the power supply network (total substation) trips, resulting in most of the power outages in the network area.
