C++標準庫裏面沒有提供的字符分割函數split ,需要自己編寫。
#include <vector>
#include <string>
#include <iostream>
using namespace std;
std::vector<std::string> split(const std::string& str, const std::string& delim)
{
std::vector<std::string> res;
if ("" == str)
return res;
//先將要切割的字符串從string類型轉換爲char*類型
char * strs = new char[str.length() + 1];
strcpy(strs, str.c_str());
char * d = new char[delim.length() + 1];
strcpy(d, delim.c_str());
char *p = strtok(strs, d);
while (p) {
std::string s = p; //分割得到的字符串轉換爲string類型
res.push_back(s); //存入結果數組
p = strtok(NULL, d);
}
return res;
}
int main()
{
string s = "a,b,c,d,e,f";
vector<string> v;
v = split(s,","); //可按多個字符來分隔;
for(vector<string>::size_type i = 0; i != v.size(); ++i)
cout << v[i] << " ";
cout << endl;
}
//輸出: a b c d e f
