使用std :: generate_n

Question

我要填寫與英文字母矢量裝滿字母字符的向量。所以我寫了以下內容：

#include <iostream> 
#include <algorithm> 
#include <vector> 
#include <iterator> 

char i='a'; 
char f(){return i++;}; 

int main() 
{ 

    std::vector<char> lol(24); 

    std::generate_n(lol.begin(),lol.size(),f); 

    std::copy(lol.begin(),lol.end(),std::ostream_iterator<int>(std::cout,",")); 

} 

但std :: copy打印97,98,99...字母的ASCII代碼。我怎樣才能解決這個問題？

Answer 1

更改模板專業化爲char：std::copy(lol.begin(),lol.end(),std::ostream_iterator<char>(std::cout,","));

Answer 2

你ostream_iterator是<int>，而不是<char> - 嘗試將其更改爲<char>
