preface
- Design topic
C language game - Millionaire (simple version)
Novice Xiaobai, I hope you can make more suggestions and make progress together
1, Adopted data storage structure and its meaning
Input: judge whether to play the game
num1,num2,
a1,a2: the position on the chessboard corresponding to the cumulative number of dice rolled
fund=2000,fund2=2000: initial fund
c: Determine whether the game is terminated
b1 = b2 =: total number of throws
i=1: judge A/B to play
2, Design ideas
Step 1: judge whether the game is going on
Step 2: judge A/B players
Step 3: value dice
Step 4: judge the effect of the number thrown
Step 5: judge whether you have achieved success
Step 6: judge whether any players go bankrupt
Step 7: if there is bankruptcy, terminate the procedure, otherwise return to step 2
Step 8: judge who wins and output
Step 9: ask whether to play again
3: Difficulties and solutions in design
Difficulty 1: generating random numbers
Solution: rand function is used, but it can only be regarded as random in a certain range. Therefore, srand function is introduced to increase its randomness by using the seed of time(NULL) change
Difficulty 2: chessboard variability
Solution: using header file macro to define variables can change the size of chessboard
4: Program code

summary
Through the application of cyclic structure and selective structure, this experimental design makes me have a better understanding of these structures; Through continuous learning, I also learned the way of random number generation and the use of header files, which gave me a new understanding of program design. Using code can make it more convenient to do some work and have fun. Similarly, I can discuss and learn with my peers, so that the coding process is not boring and a good design experience. Novice Xiaobai, I hope you can make more corrections and make common progress.
