我试图为我的C ++课程编写一个程序而且我遇到了一个奇怪的问题。返回int＆＃34;骰子＆＃34;由于某种原因，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，它也会返回相同的相似随机字符。这里是完整的代码，但据我所知，相关部分只是int dice和main。

if (c == 'p' || c == 'r' || c == 'f') valid = true;
else cout << "Input invalid\n";

return c;

答案 0 :(得分：1)
您正在打印函数int dice()的地址;如果你想调用它，应该添加括号：
cout << dice() << endl;
答案 1 :(得分：1)
替换（打印功能＆＃39; s地址）
cout << dice << endl;
with（调用函数和打印结果）
cout << dice() << endl;
其余代码似乎正常。您还应该将NULL替换为nullptr - 一种表达空指针的现代方法。这也会删除编译器警告。
BTW：未使用printScreen功能。在提出问题时，您应该给我们一个最小的工作示例。这不是最小的。
