Um,
You need to allocate space for your days array on the stack or on the
heap.
When you say:
char **days;
That just declares a pointer to a char pointer, which points into No
Man's Land when you say:
days [i] = word;
To make this sample work, you should probably declare the days array as:
char *days [7];
Then days points to an array of 7 char pointers on the stack. This is
true in any flavor of C/ObjC/C++. Its a memory thing, not a C++ thing.

Sorry for being off topic, but I don't have a C++ book yet

I want to have an array of C-Strings (which as you know are arrays
themselves). The C-Strings in the array would be added at runtime and I
don't know how many there will be or how long each one will be.
Here's what I have come up with so far.
#include <iostream.h>
int main()
{
char **days;
char *word = "The length of the word would be variable";
int i;
for (i = 0; i < 7; i++)
{
days[i] = word;
}
for (i = 0; i < 7; i++)
{
cout << days[i] << endl;
}
return 0;
}
It compiles with gcc, but during runtime it quits with a Bus Error
message.
Thanks,
Sam
