Basic flow: a. Initialize 4 non-repetitive numbers b. Players have eight opportunities for guess. The correct position is not correct to B, the number is correct and the position is correct as: the number to be guess is 1234, then the result of 1563 is 1A1B, 1 number is correct and the position is correct, 3 digital correct position is incorrect 8 chance Guess the number, you can get 4A0B for victory, otherwise the failure is not complicated, the point is not more complicated: the point is nothing more than: generates no repetition random number; II: How to verify the number of players entered, compare. The first point is described in another article. The most stupid method of verifying the number is to make a double cycle, up to 4 * 4 times will be done. However, it is too stupid that it doesn't mean. Just think about a slightly smart point, as long as 4 times, it is set: the original data is Source [4], generates a number of COMSOURCE, the binary representation is used in 10 bits, where the leftmost representation 9, the rightmost representation 0, then in the binary form of COMSource contains 4 1, different locations in different points, indicating which number, such as 1234, is represented as ... 0000110. The number input by the player is input [4], and is also converted to a similar thing, and 2 is represented as .... 100, omitted is 0. In this way, when compared, COMSource & INPUT [I]> 0 means that the number of players guess is in the original number, then compare Source [i] and INPUT [I], it is obtained whether the position is correct. The method of conversion is to do a shift operation, namely: comsource | = (1 << Source [i]) This program is actually made to this algorithm ~ ~ program structure and source code: divide 3 files: main. CPP, Guess.h, Gues.cpp. Imagine to be a class-free class that is unrelated to the interface, but unfortunately considering the interface problem too much, simply written directly into a consle form. If you change, you need to rewrite the INPUT and DISPLAY functions in the Gues class. a) main.cpp: #include
Int main () {guess girl; guess.run (); system ("pause"); Return 0;} This is not good, debugging under DEV-CPP. There is an idea to write gues into a static class, which seems to be more reasonable, but there is nothing necessary. b) Guess.h // Class Automatic Or Generated by DEV-C New Class Wizard
#ifndef guess_h # Define Guess_h
