C++ 2.30 lab: phone number breakdown given a long long integer representing a 10-digit phone number, output the area code, prefix, and line number, separated by hyphens. ex: if the input is: 8005551212 the output is: 800-555-1212 hint: use % to get the desired rightmost digits. ex: the rightmost 2 digits of 572 is gotten by 572 % 100, which is 72. hint: use / to shift right by the desired amount. ex: shifting 572 right by 2 digits is done by 572 / 100, which yields 5. (recall integer division discards the fraction). for simplicity, assume any part starts with a non-zero digit. so 999-011- is not allowed. lab

#include <iostream>

using namespace std;

int main()

{

   //declare variable to store phone numbers,its area code, prefix and line number.

   long phone_number;

   int area_code, prefix,line_number;

   cout<<"Enter 10-digit phone number:"<<endl;

   //input 10-digit phone number

   cin>>phone_number;

   //logic to find area_code, prefix, and line_number.

   area_code = phone_number/10000000;

   prefix = (phone_number/10000)%1000;

   line_number = phone_number%10000;

   //output phone number in asked format.

   cout<<area_code<<"-"<<prefix<<"-"<<line_number<<endl;

   return 0;

}

Output:

Enter 10-digit phone number:

8005551212

800-555-1212

Explanation:

In the above program 10 digit phone number entered by user will be stored in the variable phone_number.

Then using this phone_number variable area_code, prefix, and line number are calculated using the following logic:

area_code = phone_number/10000000;

prefix = (phone_number/10000)%1000;

line_number = phone_number%10000;

Finally these area_code, prefix, and line_number are displayed with hyphen in between using cout statement.
