Answer to Question #210231 in C++ for Naibuka Vaude Fong

Question

The input file called IncomeRec.txt contains a list of Annual (Gross) income records of employees in a firm. You will assume that this firm contains at most 200 active staff. Each record is on a single line and the fields are separated by a single space. The names of the fields are: • Employee Lastname (initial) - char • FNPF# - integer • Age - integer • Gross_Income - integer • Resident - char An example record may have the following form: F 12345 24 40000 Y And the format of the actual file is shown below. (Note: This doesn’t show all records and for clarity, fields here are shown separated by tabs, but in the actual file they are separated by single spaces) Note: ▪ The first two lines are just header lines and can be discarded ▪ Lastname contains an initial, an alphabetical letter only; ▪ FNPF# contains a 5 digit number; ▪ Gross income contains a 3-7 digit number; ▪ Resident contains a ‘Y’ or ‘N’, representing resident or non-resident respectively
