Programming Problem HW1 Question 1

Write a function createNum() that takes as a parameter an integer n, builds an n -digit integer using input from the user, and returns the integer. The function repeatedly prompts the user to enter single, positive (>0) digits and creates a number out of them, with the first valid digit entered being the most significant and the last valid digit entered being the least significant. If the user enters a zero, a negative number, more than one digit, or anything else, the function prints a message but does not use the input when building the number. If n is less than or equal to zero, the function returns 0 . You can assume that the parameter to the function will be an integer, and your function is not required to behave reasonably on any other type of parameter. The following shows several sample interactions with the function:

    In C++ Programming Write a program in a file named SeedFinder.cpp that finds and displays all the seeds of a integer given by the user. Let’s define a seed of an integer, n, to be a positive value that equals n when multiplied by its individual digits. For example, 23 is a seed of 138 because 23 × 2 × 3 = 138. 111 is an example of a seed of itself because 111 × 1 × 1 × 1...
