WebWhat I mean is, you must remember to set the pointer to NULL or it won't work. And if you remember, in other words if you know that the pointer is NULL, you won't have a need to call fill_foo anyway. fill_foo checks if the pointer has a value, not if the pointer has a valid value. In C++, pointers are not guaranteed to be either NULL of have a valid value. Web3% and the hit time is 2 CCs. The processor also has an 8 Mbyte, on-chip L2 cache. 95% of the time, data requests to the L2 cache are found. If data is not found in the L2 cache, a request is made to a 4 CCs to process a memory request. How often is data found in main memory?
