my doubt is what is the role of “ch = cin.get()” at the last of the while loop.
and how is the loop seeing the next character bit after everytime the loop works. If ch = cin.get() is doing it then please explain how
Doubt in the code of this question
You take the first character input outside the loop, you need to process it, after that you will take the next character. This is why it is logical to have cin.get() at the end.
The loop knows the character because we have already the stored the next character in ch.
Alternatively you can write something like this.
while(true){
cin>>ch; (or you can do ch = cin.get())
if(ch == ‘\n’) break;
otherwise process the character.
}
