一次重命名多个文件的C++程序

#include <iostream>
#include <filesystem>
#include <string>

namespace fs = std::filesystem;

void renameFiles(const std::string& directory, const std::string& oldName, const std::string& newName) {
    for (const auto& entry : fs::directory_iterator(directory)) {
        if (entry.is_regular_file()) {
            std::string filename = entry.path().filename().string();
            if (filename.find(oldName) != std::string::npos) {
                std::string newFilename = filename;
                newFilename.replace(newFilename.find(oldName), oldName.length(), newName);
                fs::rename(entry.path(), entry.path().parent_path() / newFilename);
                std::cout << "Renamed file: " << filename << " to " << newFilename << std::endl;
            }
        }
    }
}

int main() {
    std::string directory = "/path/to/directory"; // 替换为目标文件所在的目录路径
    std::string oldName = "old_name"; // 替换为要替换的文件名中的旧名称
    std::string newName = "new_name"; // 替换为要替换的文件名中的新名称

    renameFiles(directory, oldName, newName);

    return 0;
