Introduction

Make 24 is a popular game among young people, with one or two players. 4 cards are randomly choosen, each of which represents 1 number. A is regarded as 1 point, and J, Q, K are all regarded as 1 point, or regarded as 11 point, 12 point, 13 point, respectively. The player tries to get 24 points on these 4 numbers by adding, subtracting, multiplying and dividing. Each number must be used and can only be used once. There are already a lot of software or apps available that provide make 24 calculation. As a fan of this game, I develop this project purely for self-entertainment and have no intention to compete with other software.

This project contains 3 editions of programs. One is developed by Visual C++ many years ago，the others are developed by Python and SQL recently. These 3 editions nothing to do with each other. The C++ edition is really a game, others are just tools.
