Problem 17 This question gives a program in which some parts of the code have been hidden. Your task is to supply the missing parts of code so that the program prints the following 10 mathematical formulas for sums of cubes. (The output from your program must match this exactly.) = = = = = 1^3 = 1 = 1^2 1^3 + 2^3 = 9 = 3^2 1^3 + 2^3 + 3^3 = 36 = 6^2 1^3 + 2^3 + 3^3 + 4^3 = 100 = 10^2 1^3 + 2^3 + 3^3 + 4^3 + 5^3 = 225 = 152 1^3 + 2^3 + 3^3 + 4^3 + 5^3 + 6^3 = 441 21-2 1^3 + 2^3 + 3^3 + 4^3 + 5^3 + 6^3 + 7^3 784 = 28^2 1^3 + 2^3 + 3^3 + 4^3 + 5^3 + 6^3 + 7^3 + 8^3 = 1296 = 36^2 1^3 + 2^3 + 3^3 + 4^3 + 5^3 + 6^3 + 7^3 + 8^3 + 9^3 = 2025 452 = 3025 = 55^2 1^3 + 2^3 + 3^3 + 4^3 + 5^3 + 6^3 + 7^3 + 8^3 + 9^3 + 10^3 = = Some pieces of code have been replaced by PART (a), PART (b), and so on. To answer the parts of this questi you should supply the C++ code that was replaced. Each answer must fit on a single line. int main() { for (int r = 1; r
