Question

I have defined a struct like this

Struct rectangle{

int x;
int y;
int z;

};

and then in my main method, i will be assigning the variables:

void main(int argc, const char *argv[])

{

   for(i=0;i<20;i++)

   {

     rectangle[i].x = 20;
     rectangle[i].y = 10;

    }

}

But I wont be assigning the ‘z’ variable of the struct anytime. Am i allowed to do this?
hope i am not asking something very dumb!!

Thanks in advance!

Answer 1

Yes, that’s fine. Any attempt to use rectangle[i].z will result in undefined behaviour,^* but that’s not a problem so long as you don’t try to use it.
