Re: Is this code to find an int in a string okay ?

Hi Guys,

Is there any better way than below to find an int in a string (e.g.
"30" in "KFStat30A")

// --------------------------------------------------------------
#include <iostream>
#include <sstream>
#include <vector>

using namespace std;

int main()
{
 vector<string> strs ;
 strs.push_back("KFStat30A");
 strs.push_back("KFStat2A");
 strs.push_back("555555");
 strs.push_back("KKKKKK");
 strs.push_back("KKKK555");

 std::string str;

 for (int i=0; i<strs.size(); i++)
 {
    str = "";

    int beg = strs[i].find_first_of("0123456789");

    if (beg != string::npos)
    {
      int end = strs[i].find_first_not_of("0123456789", beg);
      str.assign(strs[i], beg, end-beg);
    }

    cout << strs[i] << " " << str << "\n";
 }
 return 0;
}
