Using strspn:

  

#include <iostream>

#include <string.h>

using namespace std;

int main()

{

   char *string1 = "The value is 3.14159";

   char *string2 = "test ";



   cout << "string1 = " << string1 

        << "\nstring2 = " << string2

        << "\n\nThe length of the initial segment of string1\n"

        << "containing only characters from string2 = "

        << strspn( string1, string2 ) << endl;

   return 0;

}
