I need to format my output to look like this: Movie Name: "Death Grip" Adult Tickets Sold: 378 Child Tickets Sold: 127 Gross Box Office Profit: $ 2673.00 Net Box Office Profit: $ 534.60 Amount Paid To Movie C.:$ 2138.40 The C++ code are below. I cannot make the result look like the above for some reason because I do not get the format code: #include <iostream> #include <iomanip> using namespace std; void main() { float AdultTicket=6, ChildrenTicket=3, ATicket, CTicket, GrossProfit,NetProfit,AmountPaidCompany; char MovieTitle[80]; // ask for information cout<<"what is the name of the movie?"< cin.getline(MovieTitle,80); cout< cout<<"How many adult tickets were sold?"< cin>>ATicket; cout< cout<<"How many Children tickets were sold?"< cin>>CTicket; cout< //calculating profit GrossProfit=(ATicket*AdultTicket)+(CTicket*ChildrenTicket); NetProfit=GrossProfit* float(.2); AmountPaidCompany=GrossProfit* float(.; //Display data cout< cout.setf(ios::fixed | ios::showpoint); cout<<"Movie Name:"< cout<<"Adult Tickets Sold:"< cout<<"Children Tickets Sold:"< cout<<"Gross Box Office Profit:"< cout<<"Net Box Office Profit:"< cout<<"Amount Paid to Movie Co.:"< } [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

I would set the field width for each field output and ensure that the widths of each corresponding field on each line are the same. This should fix your problem. For example: // Start output on the left end of the field cout << left; cout << setw(30) << "Movie Name:" << setw(20) << MovieTitle << endl; cout << setw(30) << "Adult Tickets Sold:" << setw(20) << int(ATicket) << endl; cout << setw(30) << "Children Tickets Sold:" << setw(20) << int(CTicket) << endl; cout << setw(30) << "Gross Box Office Profit:" << setw(20) << GrossProfit << endl; cout << setw(30) << "Net Box Office Profit:" << setw(20) << NetProfit << endl; cout << setw(30) << "Amount Paid to Movie Co.:" << setw(20) << AmountPaidCompany << endl; [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

More generally, I tend to use user-defined logical markup. So I would define manipulators like label, money, etc., and write something like: std::cout << label << "Gross Box Office Profit:" << money( 20 ) << GrossProfit << std::endl ; That way, if I decide later that I want to display the monetary values without cents, I only have to change the code in one place. -- James Kanze GABI Software Conseils en informatique orientée objet/ Beratung in objektorientierter Datenverarbeitung 9 place Sémard, 78210 St.-Cyr-l'École, France, +33 (0)1 30 23 00 34 [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

Assumming that the string constants don't ever change in the program text, otherwise it will be a pain to manually repad them everytime they do change. By having fixed width fields you can just define the width of the fields in a constant somewhere and change those if need be. Quote: More generally, I tend to use user-defined logical markup.

Cool, that's a good idea. [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

By having fixed width fields you can just define the width of the fields in a constant somewhere and change those if need be. It depends. Typically, I would expect to find such strings in a table of labels, and not isolated. The table would then look something like: char const* labels[] = { "Adult Tickets Sold: ", "Child Tickets Sold: ", "Gross Box Office Profit: ", "Net Box Office Profit: ", "Amount Paid To Movie C.: ", } ; When editing, you just use replace mode, instead of insert mode, in your editor. (And make sure, of course, that you don't accidentally overwrite one of the closing ".) -- James Kanze GABI Software Conseils en informatique orientée objet/ Beratung in objektorientierter Datenverarbeitung 9 place Sémard, 78210 St.-Cyr-l'École, France, +33 (0)1 30 23 00 34 [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.
