C++怎么读取INI或YAML配置文件_C++配置文件解析与库选择指南

#include "SimpleIni.h"
#include <iostream>
<p>int main() {
CSimpleIniA ini;
ini.SetUnicode();
SI_Error rc = ini.LoadFile("config.ini");
if (rc < 0) {
std::cout << "无法加载配置文件\n";
return 1;
}</p><pre class="brush:php;toolbar:false;"><pre class="brush:php;toolbar:false;">// 读取字符串
const char* name = ini.GetValue("user", "name", "default_name");
// 读取整数
long age = ini.GetLongValue("user", "age", 0);
// 读取布尔值
bool active = ini.GetBoolValue("user", "active", false);

std::cout << "Name: " << name << "\n";
std::cout << "Age: " << age << "\n";
std::cout << "Active: " << (active ? "yes" : "no") << "\n";

return 0;
