c language switch Why

The best practices of default in C language: place it at the end of the switch statement as the default processing for unmatched values; it is used to deal with unknown or invalid values ??to improve program robustness; avoid duplication with case branches to maintain conciseness; comment clearly on the purpose of the default branch to improve readability; avoid using multiple default branches in one case to maintain clarity; keep the default branches concise and avoid complex operations; consider using enumeration values ??as case conditions to improve maintainability; in large switch statements, use multiple default branches to handle different situations.

Best practices for default in C language

In C, the default tag represents the default branch of the switch statement, and it will be executed when no other branch matches the given value. Here are the best practices for using default:

Placement location

The default branch should always be placed at the end of the switch statement. This is because the compiler processes branches in order, putting the default branch at the end ensures that it is executed only if no other branches match.

Warning and error handling

The default branch can be used to handle unknown or invalid cases. It can help improve program robustness by showing warning messages to users or logging errors.

Avoid redundancy

It is unnecessary to repeat the default branch's function in the case branch. If a specific case behaves the same as the default branch, the default branch should be deleted.

Use Comments

For complex switch statements, comments can help explain the purpose of the default branch. Clearly explaining why certain values ??do not have their own branch can improve the readability and maintainability of the code.

Avoid using duplicate defaults in case

Using multiple defaults in a single case branch obfuscates the code and leads to unexpected behavior. If case needs to handle multiple situations, use nested switch statements or if-else statements.

Other suggestions

  • Keep the default branch concise and avoid complicated operations.
  • If possible, use enum values ??as case conditions for switch statements, not constants.
  • In a large switch statement, consider using multiple default branches to handle different error types or situations.

Following these best practices can help you use default effectively and clearly, improving the robustness and readability of your program.

What is a stablecoin? Why are the hot searches on Douyin discussed? What is a stablecoin? Why are the hot searches on Douyin discussed? Jul 09, 2025 am 06:03 AM

Stablecoins are cryptocurrencies that are pegged to assets such as the US dollar and aim to maintain stable value. They are mainly divided into three types: fiat currency collateral, cryptocurrency collateral and algorithms. 1. Fiat currency collateral types such as USDT and USCD are supported by US dollar reserves; 2. Cryptocurrency collateral types such as DAI need to over-collateralize other currencies; 3. Algorithm relies on smart contracts to adjust supply but have high risks. The reasons why it is hotly discussed on platforms such as Douyin include: as a hedging tool when the crypto market falls, a bridge for novices to enter the crypto world, a way to obtain high-yield financial management in DeFi, and the application of low-cost cross-border payments. To obtain stablecoins, you can trade through mainstream exchanges such as Binance, Ouyi, and Huobi.

PHP integrated AI intelligent picture recognition PHP visual content automatic labeling PHP integrated AI intelligent picture recognition PHP visual content automatic labeling Jul 25, 2025 pm 05:42 PM

The core idea of integrating AI visual understanding capabilities into PHP applications is to use the third-party AI visual service API, which is responsible for uploading images, sending requests, receiving and parsing JSON results, and storing tags into the database; 2. Automatic image tagging can significantly improve efficiency, enhance content searchability, optimize management and recommendation, and change visual content from "dead data" to "live data"; 3. Selecting AI services requires comprehensive judgments based on functional matching, accuracy, cost, ease of use, regional delay and data compliance, and it is recommended to start from general services such as Google CloudVision; 4. Common challenges include network timeout, key security, error processing, image format limitation, cost control, asynchronous processing requirements and AI recognition accuracy issues.
