C++ -将任何文件的字节读入无符号字符数组

#include <iostream>
#include <fstream>

int main() {
    std::ifstream file("filename", std::ios::binary | std::ios::ate);
    if (file.is_open()) {
        std::streampos size = file.tellg();
        file.seekg(0, std::ios::beg);

        unsigned char* buffer = new unsigned char[size];
        file.read(reinterpret_cast<char*>(buffer), size);
        file.close();

        // 使用无符号字符数组进行处理

        delete[] buffer;
    } else {
        std::cout << "无法打开文件" << std::endl;
    }

    return 0;
}
