Design a C++ program that first let the user enter an integer length, and then let the user enter a line of sentences not exceeding length. It is known that the sentence only contains spaces and words composed of letters, the number of words does not exceed 10, the first and last characters of the sentence are not spaces, and there is only one space between two adjacent words. The program is required to reorder all the words in the sentence according to the number of letters from less to more, and then output a new sentence after sorting, with only one space between two adjacent words.

#include #include > length; cin.get(); //remove "n' char *inputs = new char[length+1]; char *outputs - new char[length+1]; cout
