help me with my codes. how do i end the loop when i enter a value and by not breaking the loop? because when i enter a value in the seat[a] it keeps on repeating. it should return in the main loop which is the for(b=0; b<=10; b++). help me please.

First, to make a loop repeat there are many options and none of those options include calling 'main'.

Easiest way to make the program continuously loop without using up extra seats will be to simply refuse giving up the seat by subtracting one from b. So instead of doing:

1
2
3
4
5
 
    if(type != 1 && type != 2)
    {
        cout << "Please type the right number." << endl;
        return main();
    }


You do:

1
2
3
4
5
6
 
if(type != 1 && type != 2)
    {
        cout << "Please type the right number." << endl;
        b--;
        continue;
    }


Also to avoid extra work, use switch statements http://www.cplusplus.com/doc/tutorial/control statements or elseif
