截取特殊字符中间的字符串

方法一：

采用函数strtok的方式截取，示例如下：

 #include <stdlib.h>
 #include <iostream>

 using namespace std;

 int main(int argc, char* argv[])
 {
     char buf[] = "$aaaaaa$bbbbbb$cccccc$dddddddd$";
     char *cFlag = "$";
     char *temp = strtok(buf,cFlag);
     while (temp)
     {
         printf_s("%s ",temp);
         temp = strtok(NULL,cFlag);
     }
     printf_s("\n");

     system("pause");
     return 0;
 }

方法二：

采用string的方法截取，示例如下：

 #include <stdlib.h>
 #include <iostream>
 #include <vector>
 #include <list>

 using namespace std;

 void GetSubStr(list<string> &lSubSer,string str)
 {
     string sFlag("$");
     size_t sub_pos1 = 0;
     size_t sub_pos2 = 0;
     size_t strsize = str.size();

     string substr;

     cout << str.c_str() << endl;

     while ((sub_pos2 = str.find_first_of(sFlag,sub_pos1)) != string::npos)
     {
         //开始有特殊字符
         if (0 == sub_pos2)
         {
             sub_pos1 = sub_pos2 + 1;
             continue;
         }
         substr = str.substr(sub_pos1,(sub_pos2 - sub_pos1));
         lSubSer.push_back(substr);
         sub_pos1 = sub_pos2 + 1;
     }
     //末尾有特殊字符
     if (sub_pos1 != strsize)
     {
         substr = str.substr(sub_pos1);
         lSubSer.push_back(substr);
     }
 }

 int main(int argc, char* argv[])
 {

     string sStr("$aaaaaa$bbbbbb$cccccc$dddddddd$");
     list<string> lSubSer;

     GetSubStr(lSubSer,sStr);

     list<string> ::iterator it;

     for (it = lSubSer.begin(); it != lSubSer.end(); it++)
     {
         cout << it->c_str() << endl;
     }

     system("pause");
     return 0;
 }
