Which line would definitely cause the example in the notes to break down?
Why?
void main()
{
int i, * ip;
ip = & i;
ip[0] = 3;
ip[1] = 2;
ip[2] = 1;
}
The assignment ip[0] = 3; is equivalent to i = 3; and so is
safe. The next assignment ip[1] = 2; is less safe, but would probably
result in the value of 2 being asigned to the location reserved for the pointer
variable ip on most machines. Thus this statement might suceed. The
next statement is therefore unlikely to succeed, since the value of ip
may well have been corrupted by the previous line and so this line will almost
certainly cause a runtime error, "segmantation fault".
