Now to Rectify it : “what can we do???”

Modified Code:

one way:
(it will not evaluate \n)

cin.getline(arr,101,'\n');

    ch=arr[0];

    while(arr[i]!='\0') // taking \0 here, makes my code working.. please explain

    {

other way:
(it will evaluate \n as well )

   cin.getline(arr,101,'\0');
    ch=arr[0];

    while(arr[i]!='\0') // taking \0 here, makes my code working.. please explain

    {

i hope this helps,
if you have further doubt feel free to ask

Such a wonderful explanation. That means at the end of character array or string compiler itself inserts ‘\0’?

#4

yes,
bcz string is a character array terminated with ‘\0’
