Static linked lists facilitate the use of linked list structures in high-level languages without pointer types, static linked lists are described by arrays, one component of an array represents a node, and a cursor (indicator cur) is used instead of

What is the maximum value of int plus 1? Different compilation environments int does not necessarily have the same number of bytes in memory. In the usual 4-byte case, the 32-bit complement represents the largest number of 0 followed by 31 1, and if
