Refer to the exhibit. Consider the network topology. Which (if any) device in the topology has an incorrect IP address? (Assume that if two devices belong to one subnet, and another device belongs to a different subnet, that device (belonging to a different subnet than the other two devices) has an incorrect IP address.)

Write a program that prompts the user to input a string. the program then uses the function substr to remove all the vowels from the string. for example, if str = "there", then after removing all the vowels, str = "thr". after removing all the vowels, output the string. your program must contain a function to remove all the vowels and a function to determine whether a character is a vowel.
