------解决方案--------------------
throw runtime_error("wrong number of arguments");//这个事抛异常，在你机子上不能用，你把他换成打印比如printf("wrong number of arguments");
------解决方案--------------------
类似的throw 语句都改下
------解决方案--------------------

C/C++ code

if(argc!=3)
printf("wrong number of arguments");
if(!open_file(map_file,argv[1]))//你这些可以看出是要从命令行输入东西才行，所以这儿也要改下
