newbie strtok funcn

Hi,
The problem is input the phone string, break it into tokens,take area code convert it into int,append the remaining (3+4)strings ,convert into long int and display the area code and phonenumber.
Well,my problem is for the remaining strings (ie.phone num) the ouput is 0 when converted to long int.Please tell me where I am going wrong!!
Help ,I am just frustrated ..such small thing is now becoming a big stuff for me........

Code:

---

#include <cstring>
                              #include <iostream>
                              using namespace std;

                              int main()
                                                          {
                                      char phone[15]; char area[7]; char num[10]; char* tokenPtr;
                                      int areaCode;
                                      long int pnum;

                                      cout << "Enter a phone number [(###) ###-####]: ";
                                      cin.getline(phone, 15);
                                     

                                      while(tokenPtr!=NULL)
                                                                          {
                                                                                tokenPtr = strtok(phone, "()- "); //for tokenising the phonenum.
                                      strcpy(area,tokenPtr); //copy the first part into area
                                                                          areaCode = atoi(area);//converting strign to integer
                                                                       
                                                      strcat(num, tokenPtr);//appending the remaining strings to num
                                    tokenPtr = strtok(NULL, "()- ");
                                                                          }
                                           
                                     
                                      cout << areaCode << atol(num) << endl;
                                      return 0;
                                                          }

No need for the loop.
Just a general hint of advice-
When you have problems in your code, output the values to the screen at each step so you can see what they are. Many times this will lead to a solution. For example: in your program if you would have printed out the token each time you tokenized I think you might have been able to figure out what was wrong.

Took out the loop and switched a few things around.

Code:

---

#include <cstring>
#include <iostream>
using namespace std;

int main()
{
        char phone[15]; 
        char num[10];
        char* tokenPtr;
        int areaCode;
       
        cout << "Enter a phone number [(###) ###-####]: ";
        cin.getline(phone, 15);
       
        tokenPtr = strtok(phone, "()- "); //for tokenising the phonenum.
        areaCode = atoi(tokenPtr);//converting strign to integer
       
        tokenPtr = strtok(NULL, "()- ");
        strcpy(num, tokenPtr);

        tokenPtr = strtok(NULL, "()- ");
        strcat(num, tokenPtr);
       
        cout << areaCode << " " << atol(num) << endl;
        return 0;
}
