	return 0;

}

		cout << "\t1)  First Class : RM 1500" << endl;

	else if (airfareAmountin == 2)
		airfareAmount = 1100;

	else if (airfareAmountin == 3)
		airfareAmount = 800;

}


My question is : -

I wanted to pass the value of airfareAmount from airfareAmount function call which selected to main function of "X" . But , the output of "X" in main function still shows the values of airfareAmountin . For example , I want the value of "X" in main function appear as 1100 if I input the value of 2 for airfareAmount function call . Thanks in advanced .

int airfareAmount()
{
int airfareAmount; // to be returned to user once calculated
int airfareAmountin; // For input from user
// all your calculations...

return airfareAmount;}


Used in main like this:

int airfareAmount = airfareAmount();
