hi,

[c++lover]

i'm new here and i have a question regarding pointers that is here
You are required to write a program that takes a phone number as input from the user and stores it as a string value. The phone number will consist of country code, city code and actual 7-digit number separated by “-”. User can enter the phone number in any order. Your program should be able to recognize the country code, city code and 7-digit number and display it in the following format.
Country code - City code – 7-digit number

Detailed Description:

1. Take phone number as input from the user.
2. The number should be stored as a string value.
3. User can enter the phone number in any order for example 0092-333-1234567 or 333-0092-1234567 or 1234567-333-0092 etc.
4. Program should be able to recognize country code, city code and 7-digit number from the string and display it in the right sequence.

Sample Output 1
Enter the complete phone number : 0092-1234567-333

Country code is = 0092
City code is = 333
7-digit number is = 1234567
Phone number in correct sequence is = 0092-333-1234567

Sample Output 2
Enter the complete phone number : 1234567-321-0092

Country code is = 0092
City code is = 321
7-digit number is = 1234567
Phone number in correct sequence is = 0092-321-1234567

Sample Output 3
Enter the complete phone number : 300-0092-9876543

Country code is = 0092
City code is = 300
7-digit number is = 9876543
Phone number in correct sequence is = 0092-300-9876543

HINTS:
You can split the string into three parts and store each part as different string.
You should use strtok, strlen, and strcat functions
i work on it and the code that i start is here below

#include<iostream.h>
#include<string.h>
main()
{
      char string[20],*p,countrycode;
      int length;
      cout<<"Enter the compelete phone number";
      cin>>string;
      p=strtok(string,"-");
      if(p);
      cout<<p<<endl;
      p=strtok(NULL,"-");
      if(p)
      cout<<p<<endl;
      p=strtok(NULL,"-");
      if(p)
      cout<<p<<endl;
      }

and if i give it input as 1234567-333-0092 then it give outpur as
1234567
333
0092
but now further i do not know now how can i store these splitting parts into different string and how i use strlen and strcat function plz guide me
thanks in advance

why don't you try to use strlen to get the string length for three outputs, then catenate it using strcat in sequence of string length of 4, 3, and 7?
