struct Table

{

char* aTag;

char* bTag;

};

int main()

{

Table T1;

cout<<T1.aTag;

cout<<T1.bTag;

return 0;

}

This might be crazy but... i really need to know
is there any way to so that we can only write 
cout<<aTag 

cout<<bTag
instead of 
T1.aTag
like we do in 
namespace
by 
using namespace <something>
for a block.
Can in be done for pointers 
T1->aTag
.
I tried something but have to write each of them for different object... ]]> C++ Rhohitman http://www.daniweb.com/forums/thread227305.html Dynamic Memory allocation http://www.daniweb.com/forums/thread227285.html Fri, 02 Oct 2009 18:36:47 GMT
...]]> 01 Why i am not able to do this 
int* px;

px = new int[2][2];
other the 
px = new int[2*2];
is there any other method

02 Why i am not able do access through pointer dx by 
dx[1][2]
other than by using 
dx[1*7+2]

static float mat[5][7] =

        {

                -5, -4,  0,  0,  0,  0,  0,

                 6,  4,  1,  0,  0,  0, 24,

                 1,  2,  0,  1,  0,  0,  6,

                -1,  1,  0,  0,  1,  0,  1,

                 0,  1,  0,  0,  0,  1,  2

        };

        float *dx=&sim_max[0][0];

        cout<<dx[1][0];

03 why i am not able to directly initialize array of new dynamically alloc. mem to
float *dx= new float[5*7]

        (

                -5, -4,  0,  0,  0,  0,  0,

                 6,  4,  1,  0,  0,  0, 24,

                 1,  2,  0,  1,  0,  0,  6,

                -1,  1,  0,  0,  1,  0,  1,

                 0,  1,  0,  0,  0,  1,  2

        );
