customize emacs

[abdelkader belahcene <abelahcene@gmail.com>]

Hi,
Emacs is very huge software, it is not easy to customise!!!
I need customizing 2 things:

1.....     I want to change the size permanently.
I always do it   by using ,   shift+ right click  and choose the font,
unfortunately   I have to do it each time I run emacs.
I want to save this option

2.....   The indent in C++  (2 characters) is not the same in Java (4 characters ), I prefere  the C++ indentation
I mean   in  c++ :
   for(int i=0 ; i < 10; i++)
      for(int j=0 ; j < 10; j++)
          tab[i][j]  = i + j;    

    while in java :
   for(int i=0 ; i < 10; i++)
         for(int j=0 ; j < 10; j++)
                tab[i][j]  = i + j;    
That  the t of  tab  is below    r  of the second  for,  while in java  it is below  i  of int.
I want to use the C++ type.


Thanks for help
