Dynamic 2D arrays

[src]
#include< iostream.h >

void main()
{
int **a,m,n; // double pointer for 2d arry

cout<<" n enter the number of rows and coloums for matrix:";
cin>>m>>n;

a=new int *[m]; // dynamic allocation of pointers array for column
for(int i=0;i<m;i++)
a=new int [n]; // dynamic allocation of coloums for each rows

cout<<"n enter the elements:";
for(i=0;i<m;i++)
for(int j=0;j<n;j++)
cin>>a[j];

cout<<"n the elements r:";
for(i=0;i<m;i++)
{
for(int j=0;j<n;j++)
cout<<a[j]<<" ";
cout<<"n";
}

}

แล้วตอน delete ทำยังไงครับ ???

for (int j = 0; j < m; ++j) delete[] a[j];
delete[] a;

โอ้วโดนตัดหน้าซะแล้วว :D
