- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画

我正在尝试为我的 C++ 类编写程序,但遇到了一个奇怪的问题。由于某种原因,返回 int "dice"总是选择数字和字母 c 的随机组合。起初我以为我的随机数生成器是错误的,但即使我设置 dice=5 它也返回相同的相似随机字符。这是完整的代码,但据我所知,相关部分只是 int dice 和 main。

最佳答案
您正在打印函数 int dice()
的地址;如果你想调用它,应该加上括号:
cout << dice() << endl;
