C string between two pointers
WebNotice that if you compute B + strlen ("START") you will get a pointer to the first character of "messageENDxxxxxxxxx". Since you also have C, you can then copy over the characters in between (or simply set *C to '\0').

WebPointer assignmentbetween two pointers makes them point to the same pointee. So the assignment y = x;makes ypoint to the same pointee as x. Pointer assignment does not touch the pointees. It just changes one pointer to have the same reference as another pointer. After pointer assignment, the two pointers are said to be "sharing" the pointee.
