If you know, C learn! How do I get started?

To be honest, what I said may not be right. I suggest finding a teacher with a project to learn and develop software, and don't say anything else, just follow the teacher and do some odd jobs first. Then learn the ideas and processes developed by the teacher, and gradually hand over a little development work to you.

It's very quick to get started and it's very practical. It's true.

You just go to a teacher who does project development, stick to him, and give you free work, so you don't have to eat.

I also agree with 985837 that practice is really important.

I add a few:

1 Don't expect to learn in 3 days, and don't think that if you learn a hello world, you will feel that you are very good.

2 Be persistent, don't think that it takes 1 month to learn hello world, and you feel stupid and hopeless. You have to understand that your understanding may not be the same as others, so it will take different time.

3 The easiest way for people to do this is to practice more, to find opportunities to practice, to practice to learn the truth, to wait until the grammar is understood, to learn the theory, and finally to return to practice

4 Find a good teacher, try to ask a deeper level if you don't understand, and understand the deep principle, so the teacher must be a good teacher

That's how I learned.

I don't have any of your questions, just talk about my thoughts.

Any college C++ tutorial is fine, a lot of it in a used bookstore or on the Internet, it is easy to understand, no foundation is required, and then if you have the courage, apply for a computer level 2, go to a cram school, kill two birds with one stone! I learned something and got the certificate o( o

It's not good to do a good job if you don't push yourself hard these days

good luck！

Keep practicing, and then do projects.

The left and right sides of % must be integers before they can be calculated! 5%3=2, which means that taking the remainder with 3 at 5 places is 2;

31 divided by 21 equals 1, and the remainder is 10! In fact, % is to take the remainder number! 7%3=1 is 7 divided by 3 equals 2, the remainder is 1, as for the equal, it doesn't matter, only take the remainder!

31%11=9.It's very simple, 31 divided by 11 equals 2, and the remainder is 9, so the remainder is 9!

In addition, to tell you, both sides can be float, this is rounding! For example, 5 2 = 2 5%2=1.5 divided by 2 equals 2 and the remainder is 1The former is how much you take and how much you take the remainder of the latter!

5 3 = rounded to 1

31/11=2.Rounding up to get 2

So 31% 11 = 9

The remainder is the meaning of the remainder, for example, 5 2=2, the remainder is 1, he is acquainted with multiplication, that is, 5%3=2 is equivalent to 3*1+2=5, where 2 is the remainder.

Master the basic operations of cells, rows, and columns.

Master practical functions such as classification and summarization, pivot tables, etc.

Learn functions. 1. When learning functions, master the principles of functions and draw inferences from one another; If you understand a function, it will be easy to master similar functions; If you understand simple functions, it will be easy to master advanced functions.

2. Figure out function nesting, relative references and absolute references.

3. For the same problem, find a way to solve the problem in 3-5 ways, as an exercise.

Excel learning is a very interesting process, and applying the knowledge of daily life to work is the best experience!

1.The test tube touches the center of the flame and bursts.

2.The bottom of the tube is heated directly without preheating, resulting in uneven heating and bursting.

3.There is water on the outer wall of the test tube, which can cause it to burst during heating.

1.The tubes were not heated evenly.

2.The tube clamp is too tight.

3.When heated, it is in contact with the center of the lamp.

1.Heating is uneven.

2.The walls of the test tube are too thick.

3.There is a large amount of solids formed in the test tube.

A: 1If you're upshifting, it's a sign that you're driving in good traffic in front of you, so step down on the clutch quickly, put it all in gear, release it all, and quickly step on the accelerator! ~

2。Downshifting is to release the throttle first and quickly step on the clutch and then get into the gear you need to reduce Don't be in a hurry to release the clutch first, first bring a little brake on the right foot Because the inertia of the car will slide for a distance and then be ready to stop!

The gear start should be slowly lifted or semi-linked, and the speed of 2nd gear and 3rd gear must be reached, otherwise it will drag 4When you reduce the high-speed gear to the low-speed gear, you must release the clutch, otherwise the clutch will be burned (in fact, this downshift can be put into neutral first, and then according to the speed of the car, you can see what gear is hanging).

Hehe, it's very general, I hope it can help you.

1:..2nd gear plus 3rd gear, quickly lift the clutch, you don't have to stabilize at the contact point, after lifting the clutch, the throttle immediately follows.

2:..3rd gear minus 2nd gear, first release the throttle, quickly step on the clutch, immediately eat from 3rd gear to 2nd gear, immediately lift the clutch, and the throttle immediately follows.

3:..In principle, 1+2+3 should be stable at the clutch contact point, keep up with the throttle, if the operation is good, it is okay not to be stable3+4+5 do not need to be stable, fast forward gear, and immediately keep up with the throttle.

4:..The clutch must be lifted to the contact point to keep up with the throttle, if you do not reach the contact point, you will hear the sound of empty oil when you refuel, and the gear will snap when you do not release the throttle, which is easy to damage the transmission.

In short, practice makes perfect, take your time, don't rush, novices must not drive fast, remember: one slow, two look at three passes,

This is called a conditional expression, and it's a response to if....else...A concise way of writing.

Conditional operators.

The format is as follows: Expression 1?Expression 2: Expression 3

Expression 1 is the logical value, and the operation process is to find the value of expression 1 first, if true, it is the value of expression 2, otherwise it is expression 3

For example: 4>3?4:3 Answer 4

A3

Trinocular arithmetic.

Conditionals (Expressions for Logical Operations)?The value of the expression is true) :(the opposite).
