int i;
CRect rCtrlA(14,322,101,359);
CRect rCtrlB(104,322,210,359);
CRect rCtrlC(213,322,319,359);
CRect rCtrlD(322,322,428,359);
CRect rCtrlE(430,322,536,359);
CRect rCtrlF(538,322,624,359);

// i want put CRect on my for loop.

for(i=0; i<6;i++)
{
   m_pTabRadio[i].Create(NULL, WS_CHILD|WS_VISIBLE, rCtrlA, this, IDC_RADIO_MAINTAB+i);

}

You have two choices to statically initialize an array of CRect:

C++

CRect rCtrs [6] = {
    CRect (14, 322, 101, 359),
    CRect (104, 322, 210, 359),
    ...
};

or

C++

RECT rCtrs [6] = {
    14, 322, 101, 359,
    104, 322, 210, 359,
    ...
};

But even better would be that you just calculate the coordinates of your rects in the loop:

C++

const int horSpacing = 100;
const int gapWidth = 3;
for (i=0; i<6; ++i)
{
    CRect r (0, 322, 0, 359);
    r.left = 14 + i*horSpacing;
    r.right = r.left + horSpacing - gapWidth;
   ...

That gives you a perfectly even spacing and is easier to maintain in case the dimensions of your dialog change or the number of your controls grows.
