Answer 1

i&#039;m guessing a bit here but I think you&#039;re trying to input a city number (which relates to the index of the city_price array) and number of tickets a person wants to buy. Then you want to show the user how much their &#039;order&#039; costs in total? If so you want something like this:

double city_price[6] = {56.79, 105.69, 93.49, 155.99, 87.49, 73.99};

int cityNumber = 0;

int tickets = 0;

double totalCost = 0;

char response;

do

{

cout &lt;&lt; endl &lt;&lt;endl &lt;&lt;&quot;What is the number of your desitantion city?&quot;;

cin &gt;&gt; cityNumber;

do

{

cout &lt;&lt; endl &lt;&lt; endl &lt;&lt;&quot;How many tickets do you wish to purchase?&quot;;

cin &gt;&gt; tickets;

}

while (tickets &lt; 1 || tickets &gt; 5)

cout &lt;&lt; endl &lt;&lt; endl &lt;&lt; &quot;The cost is: &quot; &lt;&lt; city_price[cityNumber];

cout &lt;&lt; endl &lt;&lt; endl;

cout &lt;&lt; &quot;City and Price:&quot; &lt;&lt; setw(7) &lt;&lt; city_price[cityNumber] &lt;&lt; endl;

cout &lt;&lt; &quot;Number of tickets:&quot; &lt;&lt; setw(7) &lt;&lt; tickets &lt;&lt; endl;

cout &lt;&lt; &quot;-------------------&quot; &lt;&lt; endl;

cout &lt;&lt; &quot;Your cost:&quot; &lt;&lt; setw(7) &lt;&lt; city_price[cityNumber] * tickets &lt;&lt; endl;

cout &lt;&lt; &quot;Do you wish to purchase more tickets? (Y/N): &quot;;

cin &gt;&gt; response;

}

while (response == &#039;Y&#039; || response == &#039;y&#039;);

add &lt;iostream.h&gt; to header files (.h)

Answer 3

Its nice to give him the answer, but better to include his mistakes.

You didn&#039;t declare tickets and cost and then tried to use them.

Answer 4

You haven&#039;t defined what &quot;tickets&quot; is. You have a statement that says:

    tickets = 0&lt;5;

What does that mean? If tickets is a bool, then it has the value true (since 0 is less than 5). However, I think you mean somethign else, but I can&#039;t even guess at it.

The other problems is that you&#039;re multiplying 16 numbers with this non-existent tickets - C++only allws you to multiply one number at a time.
