we know that the static can't change its value but in
functions:-
"This inside a function static variable retains its value
during various calls."
{
static sum=0; at i=3;sum=0+3;save or retains sum=3
sum=sum+n; at i=2;sum=3+2:save or retains sum=5
return(sum); at i=1;sum=5+1;save or retains sum=6
}
so the final value is 6;
if here we declare sum as auto type then it didn't retains
its value or print 1;sum=0+1;
