Vector subscript out of range

[Maese909]

Hello all. I am trying to solve this problem - http://code.google.com/codejam/contest/dashboard?c=351101#s=p1

When I run this program, i get a debug assertion failed! error dialog box pop up that says vector subscript out of range. I have looked through my code and don't see what is wrong. Anyway, here is the code I have written. Any advice is appreciated.

P.S. The file inData.txt contains the following six lines:
5
this is a test
foobar
all your base
class
pony along

The output I am getting from this is only the first case:
Case #1: test a is this

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

using namespace std; 

int main()
{
	ifstream input; //object to read the data from a file
	ofstream output; //object to write the results to a file
	int numberOfCases; //variable to store the number of cases
	char ch; //variable to check for the newline character
	string str; //variable to read each string
	vector<string> list; //vector object to store the strings

	//open the files for I/O
	input.open("inData.txt");
	output.open("outData.txt");

	//read the number of cases
	input >> numberOfCases;

	//loop structure to read each line
	for(int count = 1; count <= numberOfCases; count++)
	{
		input >> str; //read the first word in the line
		list.push_back(str); //insert the first word in the vector
		ch = input.peek(); //check if the next character is the newline character

		//while end of line is not reached, continue reading the strings in the line
		while(ch != '\n')
		{
			input >> str; //read the next string
			list.push_back(str); //insert the next string in the vector
			ch = input.peek(); //check if the next character is the newline character
		}

		//print the results
		output << "Case #" << count << ": ";
		for(unsigned int index = list.size() - 1; index >= 0; index--)
			output << list[index] << " ";

		input.get(ch); //read the newline character
		list.clear(); //clean out the vector to read the next line
	}
	
	//close the files
	input.close();
	output.close();

	return 0;
}

If you use an unsigned int to loop through your vector, you should do it from beginning to end. Otherwise, you're looking for the index to be less than zero, which will never happen!

You're amazing. Problem solved lol.
