Reading ELF file Symbol table of C++ program

Folks,

I have some program(Test.cpp) as follows,
#include<iostream>
class Abc
{
private:
int _theVar;
public :
int printVar();

};
int Abc :: printVar()
{
_theVar=10;

}
main()
{
Abc _t;
_t.printVar();
}

I compiled the program using g++ ( g++ -o Test Test.cpp)

After this i tried read the "Test ELF" file's symbol table. I am able fetch the Abc :: printVar symbol, but i am not able to fetch the _theVar of Abc class. Please help me out in solving the this issue.

Rgds,
VInod
