Answer Posted / mansi_engg
use unsigned before variable a and b in
a=1;
b=32767;
a=a+b;
b=a-b;
a=a-b;
bcoj 32767+1 =32768 which goes out of range of integer and
will be stored as -32768 which wil make the swapping
wrong.by using unsigned, addition will come in range 0-65536
and thus the process works.
