Answer to Question #193648 in C++ for Shuvo

Question

Write a program that reads words and arranges them in a paragraph so that all other than the last one are exactly forty characters long. Add spaces between words to make the last word extend to the margin. Distribute the spaces evenly. Use a helper function for that purpose. A typical example would be

  Four score and seven years ago our

  fathers brought forth on this continent

  a new nation, conceived in liberty, and

  dedicated to the proposition that all

  men are created equal.

#include <string>
#include <iostream>
#include <vector>
using namespace std;

	string tempStr;
	vector<string> list;
	for (int i = 0; i < str.size(); i++)
	{
		if (i == str.size() - 1)
		{
			tempStr += str[i];
			list.push_back(tempStr);
			break;
			
		}
		if (!isspace(str[i]))
