错误为

这么长..流的也不熟...
看错误提示好像是少;(分号)吧,自己找找吧...

[liyatang123]

这么长的代码要找错误时最好在编译器中找，贴在网页上的不好看。
你可以先用编译器的错误定位功能先找一下位置，在将找到的位置上下几行贴出来，这样大家好帮你找问题。

[riyueming184]

不知道是你贴错了还是就是这个错误：看一下main函数，结束时多了两个大括弧。

[zhanghuizi123]

outfile.close();
return 0;
}
-->}
}
箭头表示错误，5个错误都是这

[riyueming184]

main函数多了两个花括弧……，把最后那两个花括弧删掉。不会检查括弧比配吗?

[zhanghuizi123]

找了 没找着
求帮忙

[liyatang123]

是的，多了两个括号。
