4*4魔方

设计一个4*4魔方程序，让魔方各行值的和等于各列值的和，并且等于两对角线的和

class magic{public:void getdata();void setfristmagic();void generatemagic();void printmagic();private:int m[4][4];int step;int frist;int sum;};void magic::getdata(){step=2; frist=1; sum=32;}void magic::setfristmagic(){int a;int b; a=frist; b=step;for(int i=0;i<4;i++){for(int j=0;j<4;j++) {m[i][j]=a;a=a+b;}}}void magic::generatemagic(){for(int i=0;i<4;i++){m[i][i]=sum-m[i][i];m[i][3-i]=sum-m[i][3-i];}}void magic::printmagic(){for(int i=0;i<4;i++){for(int j=0;j<4;j++) cout<<m[i][j]<<"  ";cout<<endl;}}int main(){magic mag1;mag1.getdata();mag1.setfristmagic();mag1.generatemagic();mag1.printmagic();system("pause");return 0;}
