cin >> choice;

if (choice == 1)

{

getline(cin, Id);

}

Expert Solution

Step 1

EXPLANATION:

There is always a whitespace left in the input stream when we click the enter button after taking an input.
The getline() function consider the whitespace or new line character as input.
So, it does not stop the program to get the input.
After getting the input for choice, we need to clear the new line character that exists in the input stream.
The “cin.ignore()” function is used to clear input stream.
Before, using the getline() function, call the “cin.ignore()” to clear the new line character.
The following program shows the modified code which gets input for lname or id based on choice value.
