#include<iostream>
using namespace std;

cout<<" do you want to start the program <0 > to exit any other key to start \n";
cin>>select;
if(select==0)
{
exit(0);
else

system("cls");
cout<<"- welcome to airplane program -\n";

When you post code, use

 tags.
[code]if(select==0)
{//this parenthesis is not matched
exit(0);
else ...

switch(select1)
{
case 1:
cout<<"how many tickets do you want to buy to this city:";
cin>>i;
price=city_array[0]*i;
cout<<"Price"<<city_array[0];
cout<<"total price"<<price;
break;
//etc...
}//switch (select 1) 

This code is bad. You put things in array to avoid it. It could be

if(select1 <= 5 && select1 >= 1){
   cout << "how many?";
   cin >> i;
   cout << city_array[select1-1];
   cout << city_array[select1-1]*i;
}else cout << "invalid";

So, what's wrong with a loop?

[malikrgc]

thank you for suggestion ""if else "" i need to use for loop because teacher want it with for loop

[hamsterman]

What should you use the loop for? Repeating the program until user chooses to exit?

[malikrgc]

yes until user press 0 to exit program will ask again again
and every return back program will clean everything and start again
how do you think i can do it ?

[hamsterman]

Well, this isn't really the task for a for loop, but whatever.
Just wrap the code you want to repeat in for(;;){ and }. Note for(;;) is an infinite loop (this is not a problem, since you'll exit it with exit(0);). You could use while(true) as well.
