Answer / mms zubeir
I would like to quote two things from the same area.
1. Read/Write chunks from/into a file instead of byte by
byte reading.
2. Aquire resources late and relieve it early. Example, if
you want to use a file, open the file as late as possible
and release it as early as possible after use.

Answer / maria
1) For checking modulo use
num1&(num2-1)
instead:
num1%num2
2) For multiplying or dividing by 2 use left and right shift
accordingly.
3) In loop use, if code allows it, decrement,like this:
for(int i = MAX_VALUE ; i > 0 ; i--)
instead:
for(int i = 0 ; i < MAX_VALUE; i++)
