In C++

Using a while loop, get number from the keyboard until the first number entered is repeated. In other words, use the first number as the sentinel for the loop.

Output the largest number entered.

Do not count the sentinel as one of the numbers!

Example:

Input a number

10

Input a number

5

Input a number

9

Input a number

4

Input a number

3

Input a number 10

The largest number entered was 9

Make sure you prime the loop properly.
