Problem with 2-d Character Array

The output I expected was:

alpha
beta

I used the following code:

#include<iostream.h>
#include<conio.h>
void main()
{
    clrscr();
    char choice[2][5]={"alpha","beta"};
    cout<<choice[0]<<endl;
    cout<<choice[1];
    getch();
}


But this is what comes: alphabeta
beta

Can anyone tell me what I did wrong? Thank you.

P.S.:I know I am not using standard c++, but this is how we have to do in school.

There is not enough room in your array to hold "alpha". The C-string "alpha" ends with an additional '\0'(NUL)-character and thus needs 6 chars in the array.
char choice[2][6]={"alpha","beta"};
should work.

Thanks a lot Caligulaminus, it worked. I thought that, since "alpha" is held from choice[0][0] to choice[0][4], choice[0][5] should hold the null character.

Thanks again. :)
