如何在另一个类中访问结构类型2d数组 [英] How to access struct type 2d Array in another class

问题描述

我已经从一个struct创建了一个2D数组，下面是我的代码.

Hi, i have created a 2D array from a struct and below is my code.

class RangeValues
{

public:
    
    
     struct RangeStruct{

        int LabelNo;
        double MinValue;
        double MaxValue;
    };
RangeValues(void);
~RangeValues(void);
RangeStruct MyRangeArray[2][88];
};

我已经在RangeValues.cpp类中初始化了值，并且效果很好...

现在，我想从其他类访问MyRangeArray..

i have initialized values in RangeValues.cpp class and it works fine...

Now i want to access MyRangeArray from a different class..

RangeValues range;
double LabelValue = range.MyRangeArray[0][1].LabelNo;

但是，当我打印该值时，它会给出一个很大的负数.

例如:

But when i print the value it gives something like a big negative number.

ex:

LabelValue  -858993460.00000000 

但是它应该等于1..(MyRangeArray [0] [1] .LabelNo包含数字1)

我的代码有什么问题?谢谢..

But it shoul equals to 1..(MyRangeArray[0][1].LabelNo contains number 1)

What is wrong with my code? Thank you..

推荐答案

您可以按原样使用代码.您正在处理堆栈上的未初始化数据.您应该为您的结构添加一个构造函数，并将该结构中的所有值初始化为某种值.当您在堆栈上实例化类时，该数组将具有一致的值.

You can use your code pretty much as is. You are dealing with uninitialized data on the stack. You should add a constructor for your struct, and initialize all values in the struct to something. When you instantiate your class on the stack, the array will have consistent values.
