During the execution of C + + program, the general direction of memory is divided into four areas Code area: it stores the binary code of the function body and is managed by the operating systemGlobal area: stores global variables, static variables and constantsStack area: automatically allocated and released by the compiler to store function ...

The links of the previous series of articles are as follows: Fundamentals of data structure: P1 - Basic Concepts Basic data structure: P2 1 - linear structure - > linear table Basic data structure: P2 2-linear structure - > stac ...

1, Recursion It is known that the Fibonacci sequence Fn = Fn − 1 + Fn − 2 (n > = 3), F1 = 1,F2 = 1. The nth term of the sequence is solved recursively. Input format: Enter a positive integer n (1 < = n < = 40). Output format: Output a number, the nth item of the sequence Input example 1: 1 No blank lines a ...

Design Title: Introduction to Tingzi Game Design and Implementation: A tandem game in Tingzi grid in which two players representing O and X alternately fall in the grid. Any three players form a straight line to win. Today, Xiao Ming invented a new game: 1) The size of the chessboard 3x3, the winning conditions remain unchanged; (2) If a part ...
