C++ 将一个方法的返回值作为参数传递给另一个方法，在一个单独的方法中

我保证这比听起来要简单。我已经查看了其他帖子，但还没有成功找到任何内容

我有一个方法

AList:：generateradom（）

：

以下是其他方法的内容

int ReadRandomAmount(){
        int randomAmount;        // used to collect the user's input
        cin >> boolalpha >> randomAmount;

        while (! cin.good() || randomAmount < 0 || randomAmount > 50) {

                cin.clear();

                cin.ignore(80, '\n');

至少在你发布的代码中，
randomLimitLow
从未声明过。将其声明为
int
是否有帮助？步骤1：不要使用
srand
/
rand
-你会得到非常糟糕的随机数。请参阅和。你声明了
ReadRandomAmount（）
在
AList
类定义中？您似乎将其作为一个全局函数。我没有发布定义，但它们都在那里，在我尝试将ReadRandomLimitLow的返回值包含为参数之前，它们都工作得很好。我的水晶球告诉我，您已经定义了一个全局
ReadRandomAmount
函数，nt
AList:：ReadRandomAmount
成员函数。但在过去400年左右的时间里，它一直存在接收问题。
