用C++实现存储卡部分删除数据的恢复

#include <iostream>
#include <fstream>

int main() {
    std::ifstream inputFile("storage_card.bin", std::ios::binary);
    std::ofstream outputFile("recovered_data.bin", std::ios::binary);

    if (inputFile && outputFile) {
        // 读取存储卡数据
        inputFile.seekg(0, std::ios::end);
        std::streampos fileSize = inputFile.tellg();
        inputFile.seekg(0, std::ios::beg);
        char* buffer = new char[fileSize];
        inputFile.read(buffer, fileSize);

        // 恢复删除的数据
        // TODO: 实现恢复算法

        // 将恢复的数据写入新文件
        outputFile.write(buffer, fileSize);

        delete[] buffer;
        std::cout << "数据恢复成功！" << std::endl;
    } else {
        std::cout << "文件打开失败！" << std::endl;
    }

    inputFile.close();
    outputFile.close();

    return 0;
}
