C++ 为什么我的数组值正在消失？

我的主要目标是填充一组索引。这些索引将从多个墙对象中检索，每个墙对象都包含自己的6个索引数组

这些墙对象存储在两个阵列中，一个用于行，一个用于列

以下是Wall类：

请帮帮我！谢谢

如果您的复制构造函数只有：

Wall::Wall(const Wall& other)
{
    //copy ctor
}

这就是问题的根源。要么让编译器为您生成它，要么正确地实现它

Wall::Wall(const Wall& other)
{
    for ( int i = 0; i < 6; ++i )
    {
       indices[i] = other.indices[i];
    }
}

Wall:：Wall（const Wall和其他）
{
对于（int i=0；i<6；++i）
{
指数[i]=其他指数[i]；
}
}

赋值运算符也有同样的问题（感谢@πάντα）ῥεῖ).

谢谢，但没有帮助。我编辑了问题以显示我的输出。@p1g1n当然也适用于赋值运算符！成功了！谢谢！

//This function tests the indices array contained within each wall of the rows array.
void getIndices()
{
    int index = 0;
    int * verts = NULL;

    for (int i = 0; i < numRows; ++i)
        rows[i].testWall();
/*

        verts = rows[1].getIndices();
        for(int j = 0; j < 6; j++){
            indices[index] = rows[i].indices[j];
            //cout << indices[index] << " ";
            index++;
        }
    }

    for (int i = 0; i < numColumns; i++){
        verts = columns[i].getIndices();
        for(int j = 0; j < 6; j++){
            indices[index] = verts[j];
            cout << verts[j] << " ";
            index++;
        }
    }

}

const int numVertices = 242, numColors = 242, numRows = 110, numColumns = 110;
const int numIndices = (numRows + numColumns) * 6;

vec4 vertices[numVertices];

Wall rows[numRows];
Wall columns[numColumns];
GLint indices[numIndices];
