把上述代码保存为zipwriter.cpp，然后编译执行，并用unzip工具观察生成的文件
g++ zipwriter.cpp -o zipwt /par/zlib-1.3.1/contrib/minizip/zip.c /par/zlib-1.3.1/contrib/minizip/ioapi.c -L /par/zlib-1.3.1 -I /par/zlib-1.3.1/ -I /par/zlib-1.3.1/contrib/minizip /par/zlib-1.3.1/libz.a -Wno-register -Wno-cast-qual./zipwtunzip -l example.zip
