reading the input from file phone.txt and writes them to output.txt

[tnt84]

I wrote a C++ source code as "phone.txt" that is below and now I want a program that reads the input from this file "phone.txt" and writes the input to "output.txt "


#include <iostream>
#include <string>

using std::cout;
using std::endl;
using std::cin;
#include <cstring>
#include <cstdlib>

int main()
{
const int SIZE1 = 20;
const int SIZE2 = 10;

char p[ SIZE1 ];
char phoneNumber[ SIZE2 ] = { '\0' };

char *tokenPtr;
char *areaCode;
char *phone;

cout << "Enter a phone number in the form [phone]:\n";
cin.getline( p, SIZE1 );



areaCode = strtok( p, "()" );


tokenPtr = strtok( 0, "-" );

strcpy( phoneNumber, tokenPtr );

tokenPtr = strtok( 0, "" );

strcat( phoneNumber, tokenPtr );

phone = phoneNumber;

cout << "\nThe string is\n" << areaCode << phone << endl;
return 0;
}
