Write a complete C++ program in a project called 07_2_IsSorted that reads a number of integers from a text file named numbers.txt. The sentinel value is -999. The following data file has 12 values and a sentinel value of -999. 2 3 5 7 8 10 12 13 15 1 11 15 -999 Your program must print out to the screen each integer value (five values per line right justified in a field of 3). After outputting all values, output the number of integers read (excluding the sentinel value), the sum of all numbers, and SORTED if the values are in order from smallest to largest; otherwise, output NOT SORTED. HINT: Write and test the code to produce the Count, then the Sum, then the SORTED portion of the project.

*** Number Cruncher ***

Count: 12

Sum: 102

NOT SORTED
