为什么呢
magic_cube::magic_cube( QWidget* parent, const char* name)
: QGLWidget( parent )
{
xx=0;
yy=0;
zz=0;
dx=0.0;
dy=0.0;
dz=0.0;
X = 45.0;
Y = 45.0;
Z = 0.0;
for (int m=0;m<27;m++)
{
for (int i=-1;i<2;i++)
{
for (int j=-1;j<2;j++)
{
for (int k=-1;k<2;k++)
{
Positions[m][0]=i;
Positions[m][1]=j;
Positions[m][2]=k;
printf("%d %d %d\n", Positions[m][0],Positions[m][1],Positions[m][2]);
}
}
}
}
for (int i=0;i<27;i++)
{
printf("%d %d %d\n", Positions[i][0], Positions[i][1], Positions[i][2]);
}
}
这是个构造函数，先用循环给2维数组赋值，赋值后输出的Positions
1 0 0

1 1 -1
1 1 0
1 1 1
-1 -1 -1
-1 -1 0
-1 -1 1
-1 0 -1
-1 0 0
-1 0 1
-1 1 -1
-1 1 0
……
但是紧接着再用循环输出每一行
1 1 1
1 1 1
1 1 1
1 1 1
1 1 1
1 1 1
1 1 1
1 1 1
……
都变成1了
[解决办法]
没有啊。。。我这儿很正常呢。。
