[英]Error in a function used to find the position of an element in a vector of string (c++)
我有以下運行良好的函數,可用於在字符串向量中查找字符串的位置:
int FindIndexString(vector <string> *Names, string *name)
{
auto it = find(Names->begin(), Names->end(), name->c_str());
if (it == Names->end())
{
error("FindIndexString: %s not found",name->c_str());
}else{
auto index = distance(Names->begin(), it);
return((int)index);
}
}
我需要在抱怨“自動”說明符的R程序中使用此函數,並且無法使用C ++ 11進行編譯。
我將功能更改為
int FindIndexString(vector <string> *Names, string *name)
{
vector<string>::iterator it;
it = find(Names->begin(), Names->end(), name->c_str());
int pos = (int)distance(Names->begin(), it);
if(it==Names->end())
{
error("FindIndexString: %s not found",name->c_str());;
}else{
return(pos);
}
}
但它不起作用,並且出現以下錯誤
In function 'int FindIndexString(std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >*, std::string*)':
F_Utils.cpp:92: error: no matching function for call to 'find(__gnu_cxx::__normal_iterator<std::basic_string<char, std::char_traits<char>, std::allocator<char> >*, std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >, __gnu_cxx::__normal_iterator<std::basic_string<char, std::char_traits<char>, std::allocator<char> >*, std::vector<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >, const char*)'
有什么幫助嗎?
您需要為std::find
#include <algorithm>
