Cin.peek() allows you to look at the next character in the input buffer without actually removing it. After reading 'W' into ch1, the next character in the buffer is 'X', which is what cin.peek() will return and assign to ch2. However, when cin >> ch2; is executed afterwards, 'X' is actually read into ch2, making the peek operation's effect not directly observable in the final value of ch2.
