Write a piece of C++ code that reads 10 numbers then outputs the most common number entered (i.e. the mode). If there is a tie, any tied number can be displayed. You may assume only single digit numbers will be entered (0 to 9). Write a piece of C++ code that counts the number of vowels in a sentence that is input by a user. You may assume the only vowels are "a", "e", "i", "o" and "U". You may also assume that the sentence will always end with a period. Write a piece of C++ code that asks the user how many numbers they want to enter, then finds and displays the minimum of them
