关于在vc中使用stl中的vector模板类的问题，请大侠帮忙？

[hjdaifool]

我在vc下编译一段使用的stl中的vector的程序，但是出现下列警告，但是这是在基本的模板类的使用啊，为什么在borland c++ builder中就没有呢？
程序如下：

vector<string> east(10,"beijing");
string str("daihj is great men");
string sub_str("meis");
string::size_type pos = str.find_first_of(sub_str);
char p[10]="eastcom";
east.push_back("daihj");
vector<string>::iterator end = east.end();
cout<<*(end-1)<<endl;
printf("Hello World! %d %d\n",east[2].size(),pos);
return 0;
1，warning C4786: 'std::reverse_iterator<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const *,std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::basic_string<char,std::char_

谢谢，但是我还是有点不明白：是不是如果我定义一个string类的对象，其中的字符串的长度如果超过255的话，vc编译器就会把它截断，但是stl中的string类则没有这样对字符串长度的限制？

[zhangcrony]

剛開始學這個﹐來此學習﹐順便幫樓主UP一下﹗

[greensofter]

对字符串长度应该没有限制吧，个人观点：）

[codelover]

关注，有意思的问题，那能说C＋＋builder的编译器要比VC好呢？

[SeekTruth]

VC和CB中的STL不是同一个.

[七伤拳]

C++里面类型名和变量只有前255个字符有效，STL模板展开后名称会很长，所以会报警告。
可以在 stdafx.h 里面加一句

#pragma warning(disable:4786)

C++ Builder 为什么没有可能是跟编译器的处理逻辑有关系

[七伤拳]

字符串长度不会受限制，只是变量名和类型名会有限制。
