检测数组下标边界是否超出范围
出现错误ror C2440: 'initializing' : cannot convert from 'const int' to 'class Array<int>'
No constructor could take the source type, or constructor overload resolution was ambiguous
G:\调试专业用\c++调试用\检测数组下标越界\arry_detect.cpp(64) : error C2440: 'initializing' : cannot convert from 'const int' to 'class Array<double>'
No constructor could take the source type, or constructor overload resolution was ambiguous
执行 cl.exe 时出错.
请问各位大侠 该如何修改

[解决办法]
很多粗心引起的错误啊。如果你是用的是VS编译器，那么我建议你下载个VC Assist插件。很方便，还能帮你解决不少小问题呢。
