Case Study: Implementation
void GetData( /* inout */ ifstream& dataFile,
• /* out */ int& deptID,
• /* out */ float& deptSales )
•
// Takes an input accounting file as a parameter, reads
// the department ID number and number of days of sales
// from that file, then reads one sales figure for each
// of those days, computing a total sales figure for
•//
the month. This figure is returned in
deptSales.
•//
(If input of the department ID fails due to
•//
end-of-file, deptID and deptSales are undefined.)
•//
Precondition:
// dataFile has been
successfully opened
// && For each
department, the file contains a
// department ID,
number of days, and one sales
// figure for each
day
