Article Length: 4600 Content Quality Index: ⭐⭐⭐⭐⭐ Memory Operations in C Language Embedded System Programming In embedded system programming, it is often required to read and write content in specific memory units. Assembly language has the corresponding MOV instruction, while other programming languages, except C/C++, generally do not have the capability to directly access absolute … Read more
Review of Basic Concepts of References A reference is essentially an alias for an existing variable. When we create a reference, we are essentially giving another name to a variable, and both point to the same memory address. For example: int num = 10; int& ref = num; Here, ref is a reference to num. … Read more
Pointer Operations Pointer operations give it powerful functionality. In addition to the dereference operation (*) and the address-of operation (&), pointers also support some arithmetic operations. For example, pointers can perform addition and subtraction, but it is important to note that pointer addition and subtraction are not simple numerical addition or subtraction; they are based … Read more
C++ memory management is a core topic in programming, involving complex concepts such as pointers, dynamic memory allocation, memory leaks, and memory fragmentation. C++ provides the ability to manipulate memory directly, which brings flexibility but also comes with higher complexity and the risk of errors. To aid in understanding C++ memory management, we will explore … Read more
Hello everyone! Today we are going to talk about a particularly practical and interesting topic—function pointers and callback mechanisms. In C++, function pointers are a tool that makes your code more flexible, allowing you to dynamically choose which function to execute at runtime. The callback mechanism is a classic application of function pointers, widely used … Read more
