Since the vector is holding pointers each of the sort function parameters a and b are pointers to an item* that is in the vector. They are pointers to pointers, Dereferencing a pointer to a pointer would result in an item * pointer, not an item object....

My invention relates more particularly to a new type of gauge construction in which a single pointer is adapted to be used for either indicating a pressure and then returning to zero, or for indicating a maximum pressure and remaining......
The 32 floating-pointVFP registersare arranged in four banks of eight registers each (four registers each if using double precision). Each bank can be used as a short vector when performing short vector instructions. The first bank, registerss0-s7(ord0-d3), will be used asscalarsin a shor...
You can set Windows to open an item when you single-click/tap or double-click/tap on it. The single-click option allows you to open items (ex: files and folders) with a single tap or left click, and to select items by hovering the pointer over the item. Single-click will also all...

Error byte pointer gj and the corrected data can be induced by the same procedure as that of the Hamming-type SbEC codes. Another important characteristic of the Fujiwara code exists in two-byte errors-detecting capability. That is, this code can detect two byte errors in positions i and j...
