I wanna output a matrix in right-justified fields of length 8 in C++.

You can use std::right and std::setw to get right justified fields in iostream. The default padding char is space, but you can change it with setfill(). Also, right isn't strictly necessary as I believe it is the default, but it's nice to be explicit.

std::cout << std::right << std::setw(8) << data_var

Yes

 std::right

will right justify and

std::setw(8)

will set the field width to 8.

Perhaps printf("%-8d", 1234); ?
