Write a program that prompts the user to enter 4 non-negative integer values and returns the largest of the four.
The values should not be larger than a n unsigned short int. If all the values are of the correct size, the output should be"the largest value so far is : If in the process of keying in values, the user keys in a value that is out of range, i.e. either a negative value or larger than the size of an unsigned short int as the first value, the output should be "the value is out of range/n the largest value so far is 0" If the user keys in several valid values then before the end of the process keys a value that is out of range, the output should be"the value entered is out of range! /n"The largest value so far is
