C++發現無符號字符

Question

的矢量字符我有下面的代碼的問題：

message is vector<unsigned char> 

vector<unsigned char>::iterator pos = message.begin(); 
vector<unsigned char>::iterator start = message.begin(); 
vector<unsigned char>::iterator end = message.end(); 

pos = find(start, end, ' '); 

我得到了錯誤：

error: no matching function for call to ‘find(std::vector<unsigned char>::iterator&, std::vector<unsigned char>::iterator&, char)’ 

Answer 1

你包括<algorithm>？
