language: C++ Print a shape

Write a program to accept a positive odd integer x, where x 3, and print a shape of "N", such that the height, width and diagonal length of this printed shape (measured by the number of "*") all equal to x. We assume x is already an integer, but you need to check whether x > 3 and x is an odd number. There is NO space between any two consecutive rows or columns. Because the printed shapes in the examples below are drawn manually, which appear to have one space between two consecutive rows or two columns. When you print it, please do not include such a space. Example-1 (Inputs are underlined): Please input the integer x: 5 Example-2 (Inputs are underlined): Please input the integer x: ? Example-4 (Inputs are underlined): Please input the integer x: -2 Please input the integer x: 1 Please input the integer x: 0 Please input the integer x: 3
