Vector of STL is making its size Dynamic in nature. You need not worry about its size. Just make use of functions available. It can automaticall grow as well
as Shrink depending on the elements present in the vector.

Hi Sagar,

You can do something like this:

vector< vector<int> > Y;
then in Constructor
myClass::myClass (int x, int y)
 : Y (x, vector<int>(y)) {x=a;y=b; //a and b are some values)}
fun()
{
 for (int i=1; i <x;i++)
 for (int j=0; j<y; j++)
 {
 Y[i][j] = value;
 }
}

May this helps,
Regards
