Let’s first take a look at the following piece of code. What do you think the output will be? #include <stdio.h> #define add(x) x + x int main(){ int ret = add(2) * 10; printf("%d", ret); return 0; } To understand the output of this program, we must discuss macros.This is the official explanation of … Read more
1. Conclusion The process is divided into the following four steps. Preprocessing: This step handles all directives that start with #. File Inclusion: Inserts the header files specified by the <span>#include</span> directive into the source code. Macro Expansion: Replaces the macros defined by <span>#define</span> with their corresponding values. Conditional Compilation: Determines whether to include certain … Read more
The C++ compilation process is the procedure of converting human-readable source code into a computer-executable binary file. This process can be divided into four core stages: preprocessing, compilation, assembly, and linking. Each stage has specific tasks that collectively ensure the code is correctly transformed into an executable program. 1. Preprocessing Preprocessing is the first stage … Read more
This article is generated by Tencent Yuanbao, with content outline and verification provided by @Xiao Hui~ The compilation process of GCC (GNU Compiler Collection) is a complex multi-stage process that converts human-readable source code into machine-executable object code. This process mainly includes preprocessing, compilation (which can be further divided into five sub-stages), assembly, and linking. … Read more
The compilation and linking process of C language converts the source code of a C program we write into executable code that can run on hardware. This requires compilation and linking.The process is illustrated as follows: This article explains the work done during the compilation process of C language, which is helpful for understanding the … Read more
1. Basic Principles and Complementarity of GM and LSTM 1. Core Features of the GM Model Basic Principle: The original unordered sequence is transformed into a smooth sequence with exponential regularity through Accumulated Generating Operation (AGO), establishing a first-order differential equation (e.g., GM(1,1)) for prediction. Its mathematical form is: where X is the accumulated sequence, … Read more

“Introduction: What happens between a line of C++ code and an executable binary file? Today, we press the slow-motion button and follow the steps of GCC to explore this process.” Hello, C++ developers. When developing C++ in a Linux environment, GCC (GNU Compiler Collection) is almost an unavoidable king. Most of us have probably typed … Read more
