4. Write a complete program, including headers and directives (i.e. begin with #include). Implement a program that computes the alternating sum of the numbers input by the user. Your program will ask user to type in numbers until the user input an non-number. Then, store all the numbers in a vector called myvector (The non-number user input should not appear in myvector). And then, write a function called alternating_sum, which will do the math of alternating sum on a vector. Call the function on myvector, and print the result out on console. For example, if the user input 4.6 3 2 8.9 0 4 Q, then the vector should contains 4.6, 3, 2, 8.9, 0, 4 and it will compute 4.6 - 3+2 - 8.9 +0 – 4. The output on console should be "The alternating sum is -9.3" Hint1: You don't need #include in this problem Hint2: You can assume the only character (letter) the user may input in 'q' or 'Q'. Note: Do NOT use arrays or pointers. Use vectors instead, if needed.
