Writing C in VS Code is not only feasible, but also efficient and elegant. The key is to install excellent C/C extensions, which provide functions such as code completion, syntax highlighting, and debugging. VS Code's debugging capabilities help you quickly locate bugs, while printf output is an old-fashioned but effective debugging method. In addition, when dynamic memory allocation, the return value should be checked and the memory should be freed to prevent memory leaks. Debugging these issues is convenient in VS Code. Although VS Code cannot directly help with performance optimization, it provides a good development environment for easy analysis of code performance. Good programming habits, readability and maintainability are also crucial. Anyway, VS Code is
Waving the wand of C in VS Code: A combination of efficiency and elegance
Many friends asked me, can I write C well in VS Code? The answer is: not only can, but also can write very well! This article will talk about how to gracefully navigate the fierce horse of C in VS Code, and share some of my years of experience and experience in trampling on pitfalls. After reading it, you can not only write C in VS Code, but also write better than before.
VS Code itself is just an editor, and its power lies in its powerful expansion ecosystem. To make VS Code an excellent C/C development environment, we need some key extensions. Among them, the most important thing is an excellent C/C extension, which can provide functions such as code completion, syntax highlighting, debugging, etc. I personally prefer the official Microsoft one, which has comprehensive functions and timely updates. After installing the extension, VS Code will automatically recognize your C code and provide corresponding syntax support.
The C language itself is concise and powerful, but its pointer operation and memory management are easy to cause headaches. The debugging function of VS Code is particularly important here. Set breakpoints, step-by-step debugging, and observe variable values. These functions allow you to clearly see the running process of the code and quickly locate bugs. Don't forget to learn to use printf for debugging and output. Although this trick is old-fashioned, it is still fast and effective in many cases.
Next, let’s take a look at a simple example and experience the charm of VS Code:
<code class="c">#include <stdio.h> int main() { int a = 10; int b = 20; int sum = ab; printf("The sum of %d and %d is: %d\n", a, b, sum); // 經(jīng)典的printf，好用又方便return 0; }</stdio.h></code>
This code is simple, but it shows the syntax highlighting and code completion capabilities of VS Code. When you type printf , VS Code will automatically prompt you for the parameters and usage of the function. This can greatly improve efficiency when writing complex C code.
Going further, we consider a slightly more complex situation, such as dealing with dynamic memory allocation:
<code class="c">#include <stdio.h> #include <stdlib.h> int main() { int *arr; int n; printf("Enter the size of the array: "); scanf("%d", &n); arr = (int *)malloc(n * sizeof(int)); // 動態(tài)內(nèi)存分配，記得檢查返回值！ if (arr == NULL) { fprintf(stderr, "Memory allocation failed!\n"); return 1; // 錯(cuò)誤處理，非常重要！ } // ... 使用arr ... free(arr); // 釋放內(nèi)存，防止內(nèi)存泄漏！ return 0; }</stdlib.h></stdio.h></code>
In this code, malloc and free functions are the keys to dynamic memory management in C. Remember, be sure to check the return value of malloc , and after using dynamically allocated memory, be sure to free it free , otherwise it will cause memory leaks. This is very convenient to debug in VS Code, you can set breakpoints and observe the memory usage step by step.
Regarding performance optimization, performance optimization in C language usually requires a deep understanding of algorithms and data structures. VS Code itself does not directly help you optimize performance, but it can provide a good development environment that allows you to write and debug code more easily. For example, you can use VS Code's debugging capabilities to analyze the code's runtime and memory usage to find performance bottlenecks. Remember that the readability and maintainability of the code are also important, and don't sacrifice the readability of the code in order to pursue extreme performance.
In short, VS Code plus appropriate extensions are a very excellent C language development environment. By mastering the debugging functions of VS Code and developing good programming habits, you can write C code efficiently and gracefully in VS Code. Don’t forget that continuous learning and practice are the key to improving programming skills!

What are the mainstream public chains of cryptocurrencies? The top ten rankings of cryptocurrency mainstream public chains in 2025
Jul 10, 2025 pm 08:21 PM
The pattern in the public chain field shows a trend of "one super, many strong ones, and a hundred flowers blooming". Ethereum is still leading with its ecological moat, while Solana, Avalanche and others are challenging performance. Meanwhile, Polkadot, Cosmos, which focuses on interoperability, and Chainlink, which is a critical infrastructure, form a future picture of multiple chains coexisting. For users and developers, choosing which platform is no longer a single choice, but requires a trade-off between performance, cost, security and ecological maturity based on specific needs.
Cardano's smart contract evolution: The impact of Alonzo upgrades on 2025
Jul 10, 2025 pm 07:36 PM
Cardano's Alonzo hard fork upgrade has successfully transformed Cardano from a value transfer network to a fully functional smart contract platform by introducing the Plutus smart contract platform. 1. Plutus is based on Haskell language, with powerful functionality, enhanced security and predictable cost model; 2. After the upgrade, dApps deployment is accelerated, the developer community is expanded, and the DeFi and NFT ecosystems are developing rapidly; 3.

Comparison of the differences and advantages and disadvantages of USDC, DAI, and TUSD (recently updated)
Jul 10, 2025 pm 09:09 PM
The core difference between USDC, DAI and TUSD lies in the issuance mechanism, collateral assets and risk characteristics. 1. USDC is a centralized stablecoin issued by Circle and is collateralized by cash and short-term treasury bonds. Its advantages are compliance and transparent, strong liquidity, and high stability, but there is a risk of centralized review and single point failure; 2. DAI is a decentralized stablecoin, generated through the MakerDAO protocol, and the collateral is a crypto asset. It has the advantages of anti-censorship, transparency on chain, and permission-free, but it also faces systemic risks, dependence on centralized assets and complexity issues; 3. TUSD is a centralized stablecoin, emphasizing real-time on-chain reserve proof, providing higher frequency transparency verification, but has a small market share and weak liquidity. The three are collateral types and decentralization

What is a POD (Plain Old Data) type in C ?
Jul 12, 2025 am 02:15 AM
In C, the POD (PlainOldData) type refers to a type with a simple structure and compatible with C language data processing. It needs to meet two conditions: it has ordinary copy semantics, which can be copied by memcpy; it has a standard layout and the memory structure is predictable. Specific requirements include: all non-static members are public, no user-defined constructors or destructors, no virtual functions or base classes, and all non-static members themselves are PODs. For example structPoint{intx;inty;} is POD. Its uses include binary I/O, C interoperability, performance optimization, etc. You can check whether the type is POD through std::is_pod, but it is recommended to use std::is_trivia after C 11.
