Find first 10 words and last 10 words of a string array

[Aquarius121989]

Hi everyone, I got a homework that require to count number of words in a text file and also display the first and last 10 words of the text file to the console. I have finished the counter problem and now I struggle showing the first and last 10 words. Please take a look at my code and help me figure it out. Thanks a lot

#include <iostream>
#include <sstream>
#include <string>
#include <fstream>

using namespace std;
int tokenize(string sentence, string tokenizedWords[]);
int main()
{
	string theNameOfTheFile;
	string words[100];
	string tenWord[10];
	string aLineReadFromFile;
	int countFromFunction = 0;
	string firstWord;


	cout << "Please enter the file name: " << endl;
	cin >> theNameOfTheFile;

	ifstream inputStream("C:\\Users\\aquarius121989\\Desktop\\test.txt");

	if (inputStream.is_open())
	{
		while (std::getline(inputStream, aLineReadFromFile))
		{
			if (aLineReadFromFile.length() > 0)
			{
				countFromFunction += tokenize(aLineReadFromFile, words);
				
			}
			
		}
		
	cout << "Summary for shakespeare.txt" << endl;
	cout << "The total number of words is: " << countFromFunction << endl;
	inputStream.close();
	}
	

	else
	{
		cout << "Wrong file name: " << endl;
	}

}

int tokenize(string sentence, string tokenizedWords[])
{
	string word;
	int totalWords = 0;
	istringstream toTokenize(sentence);

	while (toTokenize.good())
	{
		toTokenize >> word;
		tokenizedWords[totalWords] = word;
		++totalWords;
		
	}
	
	
	return (totalWords);
}

I guess you can use http://www.cplusplus.com/reference/sstream/ostringstream/ostringstream/

Since you're reading words, and words are just groups of characters sepearted y white space, you could simplify as follows.

Read all the words into a container
print out the size of the container
print out the first 10 members of the container
print out the last 10 members of the container.

Here's a rough example using a vector:

#include <iostream>
#include <string>
#include <vector>
#include <fstream>

using namespace std;


int main()
{
	cout << "File?" << endl;

	string file_name;
	cin >> file_name;

	ifstream input_file(file_name.c_str());
	vector<string> words;
	string word;

	while (input_file >> word)
	{
		words.push_back(word);
	}

	input_file.close();

	cout << "Number of words = " << words.size() << endl;
	cout << "First 10 words are: ";
	for (int i = 0; i < 10 && i < words.size(); ++i)
	{
		cout << words[i] << ", ";
	}

	cout << endl;

	cout << "Last 10 words are: ";
	int i = words.size() - 10;
	i = i > 0 ? i : 0;
	for (; i < words.size(); ++i)
	{
		cout << words[i] << ", ";
	}

	cout << endl;
}

In your case, perhaps don't store everything, just store the 10, and a rolling buffer of the next 10, until the end, while keeping count of everything, that shoul make it more challenigng
