I am not very clear about the changes you have made 
did u check the comments?
yes I did But it is actually not very clear
is a call possible?
I understood the error in my code but didn’t understand how cin.get() works.
1000
at the end of this thousand there is one \n character right?
so when we do ch=cin.get() , then we read that \n and put it in ch.
now if u will use while(ch!=\n) condition then this loop will not run becuase ch is already having \n.
thats why i added another line to read next character which is B.
working of cin.get() is very simple . it reads one character at a time
ohhhhhhhhhhh
coool ennough
thanks
