程序触发断点;不运行

嗨，我是一个初学者级别的程序员，我遇到了一个我一直在研究的程序的问题。重点是创建一个单独的类，该类具有由随机生成的数字组成的数组作为一个私有变量，该数组的大小以及通过使用该数组来表示该个体的适应度的数字。程序触发断点;不运行

它利用头文件，头文件的源文件和源文件来测试头文件。出于某种原因，每当我尝试编译时我都会遇到一个断点，Visual Studio也不会告诉我错误是什么。我怀疑它与我班的私人指针有关，但我不知道为什么或如何修正错误。

我试图寻找可能的解决方案（添加的拷贝构造函数和析构函数）和似乎没有任何解决问题。任何帮助将不胜感激。

要分配双

变化的数组：

genotype = new double(size); // this initialize one double and initialize value to size

genotype = new double[size]; // this creates an array which size is 'size'

您的代码超支内存时，你只分配一张双人床和写入数据到内存

for(int i = 0; i<size; i++) 
{ 
    genotype[i] = RandomFloat(); 
}
