如何在字符串中查找字符串？

Question

我必须每隔一段时间用c ++编写一次。我的问题是如何在字符串中找到字符串？然后保存该行，然后在该行中查找一组数字。例如，我有一个看起来像这样的文本文件。

地址长度名称 87623498 2只狗 12345678 4只猫 98737289 1只鸟

我想搜索“cat”，然后将与之关联的数字（12345678）和（4）存储到不同的变量名称中。这是我写的一些代码，但它并不接近正确。我有一个调用此DLL的.exe。任何帮助表示赞赏！ `     ＃包括     ＃包括     ＃包括     ＃包括     #include

char* File_Path;  //Path is sent by another program
char* Name;   //value is being sent by another program
unsigned long Address;
int Length;
int found = 0;
{
   using namespace std;
   std::string Line;
   std::ifstream infile;
   infile.open (File_Path);
   if (infile.is_open())
   {
       std::ofstream outfile;
       outfile.open ("C:\\debug\\test.txt")
       while (infile.good()  && found == 0)
       {
           std::getline(infile,Line);
           //if (Name is within Line){
           /*I want to say IF char* Name = a part of the string line 
           ie.  Name = cat and the string Line is (12345678 4 cat)
           Then store the number (12345678 = Address), and 
           (4 = Length)  I hope that makes sense :/
            */
                outfile << Line;                 //output the stored line for debug
                outfile << address;              //output the stored address for debug
                outfile << length;               //output the stored length for debug
                found = 1;
        }
            outfile.close();
            infile.close();

     }

return 0;
}

` 请帮忙！谢谢！
