Technical Unity - Kadoorie My courses 20201 - - Write a C++ program that prompts the user to input an integer (n) and outputs the sum of all integers i from 1 to n, but if i = 2 ( is an integer) then I will have a negative sign. for n = 8 the sum is equal to -1- 2 + 3-4 + 5 +6+7 -3= 6, because 1 2 4 and 8 are 2, 2, 2 and 2 respectively while 3, 5, 6, and 7 are not equal to 2 for any integer J. For example, , of sition Note: Solve this question without defining any other function apart from the main function. , i B 1
