alphabet? i is an int. How about you enter a number.

C++ is very specific...

As far as i remember, uninitialized variables can cause unpredictable results!!!

So, you have to set initial value for i variable. You can do it within single line, i.e.:

C++

int i=0;

I'd suggest to read about type casting[^]. You should convert char into integer value. You can achieve that by using atoi function[^].

I know that it is int. But just for fun, i have entered alphabet. But output is coming 7657 only. Just want to know where the alphabet is stored and why this output is coming. Thanks for your reply.

Read the answer very carefully. Learn to use a debugger.

Read the documentation: istream::operator>>. You can call cin.good() for example to ensure that the input was read (and thus is valid).
