most of the syntax errors are fixed. I don't have my compiler installed so I can't check to see if it work. Good Luck.

Re: Newbie Needs help with First Program
Here's what I have based on what we've learned so far. Doesn't compile and says "expected primary expression before 'int' on line 11. Any ideas? BTW...how do list code with the option to toggle plain text?

...and thanks a bunch!!!

#include <iostream>

using namespace std;

int main()
{
double price=0.0;
double amountTendered=0.0;
double change=0.0;

int 50_dollar_bills;
int 20_dollar bills;
int 10_dollar bills;
int 5_dollar bills;
int 1_dollar bills;
int 50CentPieces;
int quaters;
int dimes;
int nickels;
int pennies;

cout<<"Enter the Price and press Enter\n";
cin>>price;
cout<<"Enter the amount tendered\n";
cin>>amountTendered;
change = price-amountTendered;
cout>>"Here's your change....Thank You\n";

change=change*100;

50_dollar_bills=change/5000;
change=change%5000;

20_dollar_bills=change/2000;
change=change%2000;

10_dollar_bills=change/1000;
change=change%1000;

5_dollar_bills=change/500;
change=change%500;

1_dollar_bills=change/100;
change=change%100;

50CentPieces=change/50;
change=change%50;

quaters=change/25;
change=change%25;

dimes=change/10;
change=change%10;

nickels=change/5;
change=change%5;

pennies=change/1;
change=change%1;

cout>>"50_dollar_bills: ">>_50_dollar_bill>>endl"20_dollar_bills: ">>_20_dollar_bills>>endl>>
"10_dollar_bills: ">>_10_dollar_bills.>>endl>>"5_dollar_bills: ">>_5_dollar_bills>>endl>>
"1_dollar_bills: ">>_1_dollar_bills>>endl>>"50CentPieces: ">>_50CentPieces>>endl"Quaters: ">>quaters>>endl>>
"Dimes: ">>dimes>>endl"Nickels: ">>nickels>>endl>>"Pennies: ">>pennies>>endl;

return0;

}

Re: Newbie Needs help with First Program
I dunno where line 11.

I think, Error occured in following code.
Quote:
cpp Syntax (Toggle Plain Text) 
  1. int 20_dollar bills;
  2. int 10_dollar bills;
  3. int 5_dollar bills;
  4. int 1_dollar bills;
Replace with this one
cpp Syntax (Toggle Plain Text) 
  1. int 20_dollar_bills;
  2. int 10_dollar_bills;
  3. int 5_dollar_bills;
  4. int 1_dollar_bills;

You may be able to try my program (My previous post).

Quote:
BTW...how do list code with the option to toggle plain text?
You hit # symbol at message bar, [CODE ] [/CODE ] will arise, you can insert your code between [CODE ] and [/CODE ] {without space}.
For C++ language, you add ='cpp' or ='c++' after CODE, [code='cpp' ] [/CODE ]

Re: Newbie Needs help with First Program
Thanks so much for all the help folks! It turns out I had 3 small errors

1. White spaces when I declared some of my int variables.
2. I didn't change the variable "change" from a double to an integer after multiplying by 100 (convert to pennies)
3. Had several "<< " pointing in the wrong direction in the cout at the end.

Here's what gave me credit for the project:

  17.     cin>>amountTendered;
  18.     change = amountTendered-price;
  19.     cout<<"Here's your change....Thank You\n";
