帮助，无论何时我运行我的游戏，每当我在武器上调用display（）函数时，它总是返回32767！我怎样才能这样做，以便在调用显示功能时，它将武器的力量打印到控制台？提前谢谢！

随着您的代码开始像这样构建，错过细微差别变得更容易也更容易。在这种情况下，你已经与两组变量的问题发生了冲突，这两组变量意味着同样的事情，但不能区分谁在特定操作的哪一侧。
在userweap::INIT函数中，您将收到两个值来初始化对象，weappower和weaponcost。但是，不是初始化它们，而是将对象中的数据复制到参数中，然后返回。
void userweap::INIT(int id, int weappower /*input*/, int weapcost /*input*/)
{
weappower /*input*/ = power /*member value*/;
weapcost /*input*/ = cost /*member value*/;
}
这与你打算做的完全相反。因此，您的会员值power和cost永远不会故意分配值，而您的32767是来自“未定义行为”的随机数据。
帮助自己避免这种情况：给成员变量一个前缀，比如'm_'或'm'
int m_power; // member variable that stores power.
现在，您的代码将对您正在做的事情进行一些额外的指示：
void userweap::INIT(int id, int weappower, int weapcost)
{
weappower = m_power;
weapcost = m_cost;
}
加上你可以在这里避免'weapon'前缀：
void userweap::INIT(int id, int power, int cost)
{
power = m_power;
cost = m_cost;
}
更容易看到错误，正确的代码是：
void userweap::INIT(int id, int power, int cost)
{
m_power = power;
m_cost = cost;
}
答案 1 :(得分：2)
您设置的参数不是您的成员，因此power未初始化。
void userweap::INIT(int id, int weappower, int weapcost)
{
weappower = power;
weapcost = cost;
}
应该是：
void userweap::INIT(int id, int weappower, int weapcost)
{
power = weappower;
cost = weapcost;
}
另一件事：使用构造函数！
userweap::userweap(int id, int weappower, int weapcost)
: power(weappower),
cost(weapcost)
{
}
下次请到达目的地（不要发布“代码墙”）
答案 2 :(得分：1)
更改行：
weappower = power;
weapcost = cost;
他们应该是：
power = weappower;
cost = weapcost;
现在看来，你永远不会分配给power，所以它是未定义的。
答案 3 :(得分：1)
void userweap::INIT(int id, int weappower, int weapcost)
{
weappower = power;
weapcost = cost;
}
void userweap::display()
{
cout<<"power: " << power <<endl;
}
在INIT（）中，您将成员变量的值赋给参数。它需要反过来。
