واجب في structure ++c احتاج جوابة قبل يوم الثلوث >_<

هكذا يحل الفرع الأول والثاني.. يبقى عليك تفهم الفكرة وتحل الفرع الثالث

#include <iostream>
#include <string>
#include <regex>
using namespace std;

struct Phone {
string AreaCode;
string Exchange;
string Number;
};

int main() {
struct Phone origin = {"212", "767", "8900"};
struct Phone userInput;
string userPhone;

cout << "\nPlease enter phone number in format: (xxx) xxx-xxxx\n";
getline(cin, userPhone);

regex reg("[\\s()-]+");
userPhone = regex_replace(userPhone, reg, "");

userInput.AreaCode = userPhone.substr(0,3);
userInput.Exchange = userPhone.substr(3,3);
userInput.Number = userPhone.substr(6,4);

cout << "\nOrigin structure" << endl
<< "AreaCode: " << origin.AreaCode << endl
<< "Exchange: " << origin.Exchange << endl
<< "Number: " << origin.Number << endl;

cout << "\nUser Input structure" << endl
<< "AreaCode: " << userInput.AreaCode << endl
<< "Exchange: " << userInput.Exchange << endl
<< "Number: " << userInput.Number << endl;

return 0;
}
