"hard coding" means putting something into lớn your source code. If you are not hard coding, then you do something lượt thích prompting the user for the data, or allow the user khổng lồ put the data on the comm& line, or something lượt thích that.quý khách hàng đang xem: Hardcoded là gì

So, lớn hard code the location of the file as being on the C: drive, you would just put the pathname of the tệp tin all together in your source code.

Here is an example.

int main() const char *filename = "C:\mytệp tin.txt"; printf("Filename is: %s ", filename);The tệp tin name is "hard coded" as: C:mytệp tin.txt

Examples:

// firstName has a hard-coded value of "hello world"string firstName = "hello world";// firstName has a non-hard-coded provided as inputConsole.WriteLine("first name :");string firstName = Console.ReadLine();A hard-coded constant:

float areaOfCircle(int radius) float area = 0; area = 3.14*radius*radius; // 3.14 is a hard-coded value return area;Additionally, hard-coding and soft-coding could be considered khổng lồ be anti-patterns. Thus, one should strive sầu for balance between hard và soft-coding.

Hard CodingHard coding” is a well-known antipattern against which most web development books warns us right in the preface. Hard coding is the unfortunate practice in which we store configuration or input data, such as a file path or a remote host name, in the source code rather than obtaining it from a configuration tệp tin, a database, a user đầu vào, or another external source. The main problem with hard code is that it only works properly in a certain environment, and at any time the conditions change, we need lớn modify the source code, usually in multiple separate places. Soft Coding If we try very hard to lớn avoid the pitfall of hard coding, we can easily run into another antipattern called “soft coding”, which is its exact opposite. In soft coding, we put things that should be in the source code inlớn external sources, for example we store business xúc tích và ngắn gọn in the database. The most common reason why we bởi so, is the fear that business rules will change in the future, therefore we will need to rewrite the code. In extreme cases, a soft coded program can become so abstract and convoluted that it is almost impossible lớn comprehover it (especially for new team members), and extremely hard lớn maintain & debug.
