Introduction The C language was born in 1972 and has been around for 47 years, making it quite an old language. However, it remains very popular and continues to rank among the top programming languages, demonstrating remarkable vitality. C is often labeled as <span>procedural</span>, and many students have not considered or practiced developing C code … Read more
In the C language, pointers are one of the most fundamental, powerful, and easily confused concepts. They are not only tools for accessing memory but also play a crucial role in arrays, functions, structures, and many other areas. Below, I will guide you to fully understand the essence, types, uses, and examples of C language … Read more
1. Multiple Choice Questions In the following code snippet, the final value of <span><span>x</span></span> is ( ) int x = 10;x += 5 * 2;x /= 3; A. 5 B. 6 C. 15 D. 20Answer: BExplanation:<span><span>x += 5 * 2</span></span> is equivalent to <span><span>x = x + 5 * 2</span></span>, thus <span><span>x = 10 + … Read more
Dynamic memory allocation in C refers to the process where the program requests memory from the system at runtime, based on its needs, rather than determining the memory size during the compilation phase. This is key to building flexible and scalable programs. Below, I will comprehensively explain the fundamentals of dynamic memory allocation through concepts, … Read more

Function Parameter Passing MethodsIn C language, the methods of passing function parameters can be roughly divided into two types: one is pass by value, and the other is pass by address.Pass by ValuePass by value, as the name suggests, means passing the value of the actual parameter, and it is a copy of the value. … Read more
Pointers Detailed Explanation (Pointers） In the C programming language, a pointer is a powerful tool that allows you to directly manipulate memory addresses. Understanding pointers is not only key to writing good C programs but also fundamental to grasping core concepts such as memory management, arrays, and function parameter passing. 1. What is a Pointer? … Read more
We encourage clear philosophical thinking in programming rather than rigid rules. I do not expect you to agree with everything, as they are merely opinions that change over time. However, if I had not written them down until now, these opinions, based on much experience, have long accumulated in my mind. Therefore, I hope these … Read more
Hello everyone, I am Xiao Feng Ge, and today we will explore how the C language controls hardware. The Design Philosophy of C Language The design philosophy of C can be summarized as “trust the programmer“. Unlike many modern programming languages, C imposes very few restrictions on the behavior of the programmer,it assumes that the … Read more
