11 tips to improve your programming skills:
1.First analyze the problem carefully
2.Then think about how to solve the problem
3.Collect and organize all your needs.
Take some time to write down what you want to achieve with the final product, and identify who our target user groups are. If this step can be done well, it will save a lot of time later. As the saying goes, sharpening the knife will not miss the woodcutter.
4.Write a comprehensive implementation plan (or model).
If it is a small project, what comes out of this step may be just a basic process or a simple equation.
If it is a relatively large project, this step will help us cut it into several modules, and then think about the following questions:
What tasks do each module need to perform How to transfer data between modules
How to call the data in the module
Although collecting and planning requirements is boring and boring compared to writing code directly, but if this is not the case If done well, the subsequent debugging work will be particularly cumbersome. If we can take the time to design a correct program flow and structure, then we are actually halfway to success before writing the first line of code.
5.Comment our code.
If you think your code might need an explanation, comment it out. Each function should have a line or two describing its parameters and return results. Rather than telling you what, comments should explain why. Also remember to update comments when updating code.
6.Use unified naming rules to define variables.
This will help us track various types of variables and see the purpose of each variable at a glance. The benefit of this is not just as simple as making it easier for us to type X = A+ B * C, it will make our code easier to debug and maintain. A currently popular naming method is the Hungarian nomenclature, which uses the method of prefixing the type with the variable. For example, for the overall variable, we can use intRowCounter, and the string is strUserName. It doesn't matter what your naming convention is, as long as it's consistent and describes the variables simply.
7.Format and edit the code, and visualize the code structure.
For example, indent code when encountering conditional statements (if, else, etc.) and loop statements (for, while, etc.). Also, you can add a space between the variable name and the operator symbol. The operator symbol refers to "+", "-", "*", "/", and "=" (for example, myVariable= 2 + 2). This not only makes your code more intuitive and elegant, but also makes our program flow more clear at a glance.
8.Comprehensive testing.
First test whether each module can operate independently by entering the values we expect. Then try entering some possible but rare values and continue testing. This basically exposes all hidden bugs. Tests also have so-called skills. Through practice and practice, any of us can gradually build up skills that suit ourselves. Tests should include the following situations:
Extreme values: use 0 for positive values and greater than the expected maximum value; use empty strings for text, and use null for parameters.
Meaningless value. Although it is unlikely that users will enter garbled characters, it is better to test it ourselves anyway.
Incorrect value. Enter 0 for division, or a negative number if a positive number is expected and the square root is expected. When the input type is a string, enter a non-numeric value and see if it is parsed as a numeric value.
9.Practice, practice, practice.
Programming will also continue to improve with the advancement of the times. So there is always something new for us to learn - even more useful and important - and of course there is always something worth revisiting and learning the new.
10.Reduce the risk of demand changes.
In the real work environment, needs are always changing. However, if we collect requirements very comprehensively in the early stage and the implementation plan is very targeted at the beginning, then the possibility of poor planning and misunderstandings between the two parties due to changes in requirements in the later period will be much smaller.
We can improve the clarity of the process by showing the requirements document and implementation plan before starting to write code. This will help ensure that our plans are truly completed according to the client's requirements.
If you compare a project to a series of milestones, then just complete one at a time. Remember, the less there is to think about at any given moment, the more detailed and perfect we can think.
11.From easy to difficult, from simple to complex.
If your software is complex, then I suggest you start with simple modules. For example, there is such a project: please design a program that can appear a gradient graphic that follows the direction of the mouse, and can also change the shape according to the mouse sliding speed.
First, design a square and write a code that can make it follow the mouse. This way, the motion tracking problem is solved separately. Of course this is the first step.
Next, relate the size of this square to the speed of the mouse, which solves the problem of the shape changing with speed.
Finally, create the actual shape you want and connect these three components together.
Using this method, modular code can be written naturally. And each component has its own independent function. This is very useful for code reuse (for example, you can definitely apply the code from the first step (for implementing mouse tracking) in other projects) and makes our program easier to debug and maintain.
