二维指针动态创建二维数组(C/C++)

 double** p = new doube*[5600];
2 for (int i=0; i<5600; i++)
3 {
4     p[i] = new double[5600];
5 }

释放：

 for (int i=0; i<5600; i++)
2 {
3     delete [] p[i];
4 }
5 delete [] p;

C语言：

 double** p = (double**) malloc( 5600*sizeof(double*) );
2 for (int i=0; i<5600; i++)
3 {
4     p[i] = (double*) malloc( 5600*sizeof(double) );
5 }

释放：

 for (int i=0; i<5600; i++)
2 {
3     free( p[i] );
4 }
5 free( p ) ;
