first, though it's not a fix, you can just put your cin.get before thereturn. It'll hit that either way.

Second, you don't have an else statement. so:
if (i==1)
{
...
}
else if (i == 2)
{
...
}
what if I is 30? 50? -3266784? here's how we handle it:
else
{
...
}

Hi.

I thought that case only can be used on digit variables, such as int,double and such stuff.

At least the tutorial I read said that.

I tried both else if and if else before but got problems, now it sortof works.I don't get any output from my program, but I don' get any compilererrors at least.:)

Here is my code. what can I havem made wrong?
#include <iostream>
using namespace std;
int main()
{
cout <<"test";
string test;
cin >>test;
if (test=="try")
{
cout <<"nice";
cin.get();
}
 else if(test=="bad")
{
cout <<"that's bad!";
cin.get();
}

return 0;
}

    sure. how are you going to translate
    cin >> direction
    to direction quickly? for that, you may as well just use if ...
    else if... else ...

    So what?

    EnumDirection {north, south, east, west};

    Or something akin to it.

    Can I use it now? **smile**

    It is not legal to use a switch/case statement on a non-integral
    type in C++.

    if (direction == "north")
    {
    std::cout << "You go north." << std::endl;
    }
    else if (direction =="south")
    {
    std::cout << "You go south." << std::endl;
    }

    Hi.

    Now I've decided that I'll learn to do things both without goto,
    and with it. Because then I'll maybe discover that goto is bad:)

    I got one last code question today.

    I need so that my program can do more than one action. for
    example of writing a text adventure you want many.

    I've managed to put an if statement in my code. for example

    if direction=="south";

    {

    cout<<"you go south.";

    }

    Now if I want to go north, how can I do that?

    I tried if else, but it only says "expected primary expression
    before else expected.

    Can you help me with this please?
