1）是用Vector容器代替数组
2）使用数组指针（需要注意局部变量的问题，指针是否需要用new创建）
int red [ 3 ] = { 1 , 0 , 0 };
int green [ 3 ] = { 0 , 1 , 0 };
int blue [ 3 ] = { 0 , 0 , 1 };
std :: map < int , int (*)[ 3 ]> colours ;
colours . insert ( std :: pair < int , int (*)[ 3 ]>(( GLUT_LEFT_BUTTON ,& red ));
colours . insert ( std :: pair < int , int (*)[ 3 ]>(( GLUT_MIDDLE_BUTTON ,& blue ));
colours . insert ( std :: pair < int , int (*)[ 3 ]>(( GLUT_RIGHT_BUTTON ,& green ));
//Watch out for scope here, you may need to create the arrays on the heap.
3）使用结构体来构造代替数组的元素，或把数组直接放在结构体内
struct Triple
{
int color [ 3 ];
};
//Later in code
Tripple red = { 1 , 0 , 0 }, green = { 0 , 1 , 0 }, blue = { 0 , 0 , 1 };
std :: map < int , Triple > colours ;
colours . insert ( std :: pair < int , Triple >(( GLUT_LEFT_BUTTON , red ));
colours . insert ( std :: pair < int , Triple >(( GLUT_MIDDLE_BUTTON , blue ));
colours . insert ( std :: pair < int , Triple >(( GLUT_RIGHT_BUTTON , green ));
