编译环境

Qt 6.0.0
Qt 5 Compatibility Module
MinGW 8.1.0 64-bit
Qt Creator 4.14.0 (Community)
Windows 10

题目要求

先随机生成一个各位均不相同的四位数。用户输入一个四位数，如果那一位完全对应上了，A的值就加一。如果那一位没有对上，但是那个数字在原来的四位数中存在，则B的值加以。显示-A-B来提示用户。

生成的数假设为1234：

输入1234，提示4A0B

输入1753，提示1A1B

输入4321，提示0A4B

直接将Build文件夹里的 exe 文件拿出来试运行不了的，会说缺少一些 dll 文件。如果手动找到这些 dll 很麻烦而且还会出错。所以方法详见我的博客【Qt】生成 exe 文件的方法。
