Question

Modify the following program to overload the >> so that writing an object of type AltMoney can be done using >>. Your input file, in_file.dat, must have four integer values which represent, respectively the dollars and cents part of the first amount and the dollars and cents part of the second amount.
Example: for input $50.34 and $86.73, you have:
50 34
86 73

//This program adds money of two different people
// It reads the amounts for two people from an
// input file in_file.dat and writes the result into a file out_file.dat

#include<cstdlib>
#include<fstream>

friend void write_money(ofstream& ous, AltMoney m);

void read_money(istream& ins, AltMoney& m);

Explanation / Answer

here is your modified program : ------------->>>>>>>>>

#include<iostream>
#include<cstdlib>
#include<fstream>
using namespace std;
class AltMoney
{
public:
AltMoney();
friend void read_money(istream& ins, AltMoney& m);

friend ofstream& operator<<(ofstream& ous, AltMoney m);
private:
int dollars;
int cents;
};
void read_money(istream& ins, AltMoney& m);
void get_streams(ifstream& ins, ofstream& ous);
ofstream& operator<<(ofstream& ous, AltMoney m);
int main( )
{
ifstream ins;
ofstream ous;
AltMoney m1, m2, sum;
get_streams(ins, ous);
read_money(ins, m1);
ous<<"The first money is:";ous<<m1;
read_money(ins, m2);
ous<<"The second money is:";ous<<m2;
sum = m1+m2;
ous<<"The sum is:";ous<<sum;
ins.close();
ous.close();
return 0;
}
AltMoney::AltMoney()

}

ous << m.cents << endl;

return ous;
}

}

}
void read_money(istream& ins, AltMoney& m)
{
