C++之以分隔符的形式获取字符串

void CConvert::Split(const std::string& src, const std::string& separator, std::vector<std::string>& dest) //字符串分割到数组
{

//参数1：要分割的字符串；参数2：作为分隔符的字符；参数3：存放分割后的字符串的vector向量

string str = src;
string substring;
string::size_type start = 0, index;
dest.clear();
index = str.find_first_of(separator, start);
do
{
if (index != string::npos)
{
substring = str.substr(start, index - start);
dest.push_back(substring);
start = index + separator.size();
index = str.find(separator, start);
if (start == string::npos) break;
}
} while (index != string::npos);

//the last part
substring = str.substr(start);
dest.push_back(substring);

}

vector<string> ster;
vector<string>::iterator iter; //声明一个迭代器

string str="ABC|123|AC123";
string Insta;
CString pourin;
CConvert::Split(str, "|", ster);
int lenth = 0;

char charstr[200]={0};
for (iter = ster.begin(); iter != ster.end(); iter++)
{

Insta = *iter;
pourin = Insta.c_str();
string Str = CT2A(pourin.GetBuffer());
strcpy(charstr, Str.c_str());
lenth++;
}
