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
