I am just beginning to learn pointers and I have a question regarding accessing the values using the address. Suppose we have an array of say 10 elements and I begin to access all the elements starting from the 10th element, and go on untill i access the 0th element... What will happen of I access the address of the cell before the 0th element? My instructor warned me about trying such a athing, however, I'm curious as to what would happen if I do so.. Anyone here tried that? Please tell me what happens.
