Answer 2

#include<iostream>
#include<string>

//取得字符串字符个数,不限中英文
unsigned int GetStringCount(const std::string &s)
{
short ch;
unsigned cnt = s.size();
for(size_t i=0; i<s.size(); ++i)
{
ch = s.at(i);
if(ch&0x1000) ++i,--cnt;
}
return cnt;
}

//取得以0为起始索引的指定位置字符
std::string GetString(std::string &s, size_t index)
{
short ch;
std::string res;
unsigned cnt = index;
for(size_t i=0; i<s.size() && i<cnt; ++i)
{
ch = s.at(i);
if(ch&0x1000) ++i,++cnt;
}
ch = s.at(i);
if(ch&0x1000) res=s.substr(i,2);
else res=s.substr(i,1);
return res;
}

int main()
{
std::string s="点点滴滴";
std::cout<<GetStringCount(s)<<std::endl;
std::cout<<GetString(s,2)<<std::endl;
return EXIT_SUCCESS;
}
