+// Sum of the number and maximum
+Write a program that asks the user to enter integers. When the user enters the number -1, the program terminates and prints the sum of all numbers entered (before -1) and the largest number entered.
+
+Example output:
+
+Give a number: 1
+Give a number: 2
+Give a number: 3
+Give a number: -1
+Sum: 6
+Maximum: 3
