My question is a bit troublesome, and this one is in trouble

Sooner or later, the time will come, and you have the courage to face it!

Hello first ask yourself, do you really need him?

If you don't really need it, then don't wait any longer

Family factors that led to a breakup?

With all due respect, sometimes falling in love doesn't solve problems.

Are you sure you'll have the ability to protect each other's love in four years?

He may be really embarrassed, there is pressure at home, he wants to love but can't love, he doesn't dare to love, this situation is too tricky, I feel that you should contact his parents and family, and it is not a bad thing to contact his current girlfriend.

Otherwise it's hard to do, really.

What he needs now is understanding, but you don't know what to do.

etc., will not solve the problem.

Hope you understand.

1. 1. Four years ago, he was not able to defend your love, because you were immature, not deep in love, ignorant of love, and could not be regarded as true love, otherwise I believe that no family can stop you, and your he will not accept others lightly.

2. What is the reason for you to fall in love with him again after four years, is it because you miss the feeling of the first thought, or have you always missed him? I don't really believe that you will have a relationship with him for four years, during which time you have not been moved by anyone else? Why you want to be with him after four years, only you know.

2. 1. You are an unassertive and irresponsible man, because he should have chosen you four years ago, he should not pursue you after four years of "name" relationship with his girlfriend at home, he will hurt the woman he doesn't love to choose you, and you will become a woman he doesn't love in the future. Insecure man do you want?

2. When I want to be with you, you are still hesitant and afraid, and it is really dirty.

3. Have you considered the feelings of his girlfriend at home, and if you were her, would you be sad? Why should a woman embarrass a woman, after all, the two of them have been together for four years, and it is false to say that there is no relationship, otherwise why do you think he hesitates.

All I think you have to indulge in the past, such a man is not worthy of your forgiveness, even if you forgive, you are only suitable to be friends, if you become a lover, you will have a pimple in the future. I believe that there are better people waiting for you in the world!

Four years is a long time, isn't there a boy you like in between? Try to date a new boy, maybe you can find that you like it more, if he doesn't take the initiative with you, it's useless for you to be anxious, it's better not to care, wait for him to take the initiative again, I think it will be better!

Forget it, there is no need to do it again after it is all divided, this will only bring you deeper damage, if a man can abandon a woman for the first time, then he can definitely come a second time without hesitation.

Your question is a bit complicated, but sooner or later, life has to taste the ups and downs, right, face it bravely, maybe you have taken this step, and the next step will be bright.

They have been together for 4 years, even if there is no love, there are feelings, things are not as simple as you think, and you don't know much about his attitude. It's useless for him to just love you. Unless you see him working hard for your love, don't believe the phrase "I love you" easily.

Listening to you say this, your boyfriend should be an indecisive person, with what you know about him, you don't know why he doesn't see you, whether he doesn't want you to worry or is running away, he just doesn't dare to face reality!

He didn't dare four years ago, and it is the same now! Unless you're a big woman, you're not going to be happy together! (I can sense from what you say and say that you should not be a strong woman, so the best advice is not to break up).

For your own happiness, follow the following prescription:

1. Find him, or contact him, and tell him that you can give him a month to let him handle everything.

2. a. If he handles it well, the relationship with his ex-girlfriend, you love him well, and you must really love his family. And be prepared to endure the white eyes of his family in a short period of time.

b. If he doesn't handle the relationship with his ex-girlfriend, you will break up completely. Otherwise, you, him, and she will all suffer, and of course the most painful person is yourself.

Have a nice day!

Last year's data is used as the base period.

1. The impact of this year's output on the total cost: last year's total cost = 6500 * 30 * 15 = 2925000

The impact of production = 6700 * 30 * 15 = 3015000-2925000 = 90000

2. The consumption of raw materials per unit of product, 6700 * 29 * 15 = 2914500-3015000 = -100500

3. The impact of the change in the unit price of raw materials on the total cost: 6700 * 29 * 14 = 2720200-2914500 = -194300

Combined with the above scores: 90000 + (-100500-194300) = -204800

The total cost of the product was reduced by 204,800 yuan compared with the previous year, mainly due to the increase in output, the reduction of the cost of unit consumption, and the reduction of the unit price of materials.

Is there still 10-1=9 9x3=27 27+2=29 30-29=1 on the question, where is the remaining 1 yuan? 、、Actually, the 10-1=9 is to fool you, because from 9x3=27 is the money that is spent, and the 1 yuan is now the money in the hands of 3 people, so it's actually very simple... 30-29+1=30

At the beginning, the 1 yuan was not an expense, and it shouldn't be subtracted from the expenses and the money still in hand, but it wasn't clear how to calculate In fact, the waiter and the boss were in a group, 3 people were in a group, so you can think about it, the boss actually charged a total of 27 yuan (25 yuan at the beginning, plus 2 yuan from the waiter), so that the 1 yuan in the hands of +3 people 27 + 3 = 30 is not just right? Oh, I hope you can understand the explanation... Hope it helps you o(o

Subtracting 2 is right, adding 3 is true, let's put it this way, the boss returns 30 yuan, and the little two deduct 27, then they actually spent 27 yuan, do you still want to use three people to spend 27 yuan plus 27 yuan for the small two, so adding 2 is incorrect, 2 is already in 27 yuan, 27 yuan plus 3 yuan returned is 30 yuan & 30 = 2 + 3 + 25

This problem is actually a mistake in the balance between "out" and "in", here "out" is that three people each spent 9 yuan, a total of 27 yuan, and "in" is the boss received 25 yuan and 2 yuan for Xiao Er's greed, 3 * 9 = 25 + 2.

Didn't you already mention it? Isn't it? Oh, you're on a mission hehe.

You're too tired to rest.

Isn't it quite simple, it's all brought up.

Congratulations, you asked a question--

Hello! Sorry, I haven't been on lately. Only now do I see it.

Regarding setting breakpoints, I don't know if you know how to do it now. If you are using VC++, click on that hand (F9) to set the breakpoint.

The location of the breakpoint can be set at will, but don't set it behind some statement that requires input such as scanf() (or stool cin>>), if the setting is not reasonable, it will automatically move the breakpoint back to a reasonable position, or trick you into setting it again. Then you can press according to your own needs for the jujube cultivation stove

Ctrl+F5: Compile (i.e. check for syntax errors).

f7: Link (link multiple programs you have written).

Ctrl+F5: Run (that is, run the program).

f9: Set a breakpoint.

f5: Debug run (that is, after you set the breakpoint, and then click compile to run, it will stop where you set the breakpoint).

F10: Step debugging (On top of F5, run one line at a time, so you can know which line has the problem. ）

f11: Enter the body of the function you wrote (e.g. the fun() function you wrote).

Jump out of debugging: is to end debugging.

Let f(x)=ax2+bx+c

f(x)>-2x is solved as (1,3) There is only one case between the two roots: f(x)+2x<0 and "Deerta" >0 so a<0 are 1 and 3 respectively two equations about abc and then f(x)+6a=0 "deerta" = 0 The third equation is about a b c combined to solve abc. Question 2: First of all, a<0 finds the maximum value and draws a picture to see where it can be reached.

The condition is that the function value is greater than zero at the time of the vertex. And the first two equations can be solved.
