Answer to Question #9143 in C++ for alex lee

Question #9143
Write a function displayTotalCost prototyped by

void displayTotalCost(double totalCost, unsigned recordNum, bool aborted);

so that the execution of this function will first display the total sale cost stored in variable totalCost and the total number of sale records stored in recordNum. If aborted is true, then the function will also display an error message to the effect "Input terminated by invalid data at record" followed by the corresponding record value. For example, displayTotalCost(55.55, 3, false) could just display

Total sale cost (3 records) = $55.55

while displayTotalCost(66.66, 7, true) could display

Total sale cost (7 records) = $66.66
Input terminated by invalid data at record 8.
Expert's answer
void displayTotalCost(double totalCost, unsigned recordNum, bool aborted){
if (aborted) {
& cout << "Total sale cost (" << recordNum <<" records) = $" << totalCost << endl;
} else
& cout << "Total sale cost (" << recordNum <<" records) = $" << totalCost << " Input terminated by invalid data at record " << recordNum+1 << "." << endl;
}
