Debug assertion failure

[rsp19]

I continue to have this error stating

Expression: string subscript out of range when trying to run a C++ program

I have tried to debug however, the error continues to come up each time. Can you help?

Where's the code?

The problem is here:

// data for the array (parse with a space)
string num1Raw;
string num2Raw;
bool num1Proc = true; // true if processing num1, num2otherwise
for (int i = 0, j = 0; i < buffer.size(); i++)
{
	if (buffer[i] == ' ')
	{
		num1Proc = false;
		continue;
	}
	// processing num1
	if (num1Proc)
	{
		// cout << buffer[i];
		num1Raw[i] = buffer[i];
	}
	else
	{
		num2Raw[j++] = buffer[i];
	}
}
data[indexer][0] = atof(num1Raw.c_str());
data[indexer][1] = atof(num2Raw.c_str());
indexer++;
// cout << data[indexer][0] << " ";
// cout << data[indexer][1] << endl; 

It seems what you indended to do was this:

if (num1Proc)
{
	// cout << buffer[i];
	num1Raw.push_back(buffer[i]);
}
else
{
	num2Raw.push_back(buffer[i]);
}

Thank you so much, you are a life saver!

It works great now, except I cannot get the right numbers that the num2Raw variable you just fixed needs to bring in from the file. They are all set to zeros in the Y column.
