About handling dynamically variable names...

About handling dynamically variable names...

(OP)
Hi
Dear all,

I want to create dynamically multidimensional vector. Its dimension depends upon user input. According to user input i created a string which contains the name (e.g. table[2][3][4])
dynamically. Now i want to use this string to access vector variables. But i can not successful, please guide me, i will be thankful to you.

Here is my code.
*****creating matrix of test_var.size()  size*******

typedef vector< vector < unsigned int > > contingency_table;

 contingency_table table(test_var.size());
 for (unsigned int i=0; i < test_var.size(); i++)
 {
     vector <unsigned int> dim;
     table[i]= dim ;
 }
********* to access variables ************

static string str= "table";
 for ( int j=0; j < 3; j++)
     for (int k=0; k< test_var.size(); k++)
 {
     std::ostringstream table_index;
     table_index << "[" << k << "]";
     str = str + table_index.str();
     cout<<"\n string name is " << str;
 }
*****************************************

So, "str" contains the exact vector name along with index (table[2][3][4]).

Now i want to use it to insert and to retrieve value of vector table.

Thanks in advance

It's quite impossible. You need three int values to access 3D vector elements.
However I see only 2D vector in your snippet.
