Sorry people, it is more than I can bear. We all agree that
1. The assignment is stupid
2. The code is ugly
3. OP doesn't have a clue
yet none of the above gives a reason to teach things you've not be asked for.

If you have nothing to say on the subject, it is perfectly OK to remain silent.

Missed that.

Something like this will work. Check your assembler docs for the syntactical specifics. What is important, you got the idea right.

It is a very nice disclaimer. The only problem (at least in US, and I suppose in UK as well) is that it has never been tried in a court of law. Until then nobody knows if it holds water.

Sin(x) = x - x^3/3! + x^5/5! + x^7/7! ...

Just wondering: are you intentionally trying to mislead OP?

Yes, but instead of asking the user for the number N; N has to be
the sum from 2^0 -> 2^50. I though the instructions were clear enough, especially with the examples.

So the missing link in Narue's code is the summation?
Well then let's start with a few observations:
The sum itself is equal to 2^51 - 1. Assuming one decimal digit per byte a) we'd need 15 bytes or so to represent it; b) the Least Significant Digit (*) of 2th power is not zero hence subtraction of 1 is trivial; c) we just need a way to calculate a power of 2.
We can do it in a most straightforward way by means of multiply-by-two method:

int mul2(char * value, int len)
{
    int i, carry;
    for(i = 0, carry = 0; i < len; i++) {
        value[i] = 2 * value[i] + carry;
        if(value[i] >= 10) {
            value[i] -= 10;
            carry = 1;
        } else {
            carry = 0;
        }
    }
    if(carry == 1) {
        value[len] = 1;
        len += 1;
    }
    return len;
}

and call it as in

char data[20] = { 1 }; // "fifteen bytes or so"
    int i, len = 1;
    for(i = 0; i < exponent; i++) {
        len = mul2(data, len);
    }

This works, although for large exponents is highly inefficient. Which leads us to the next challenge:
Write a program which given an exponent N, designs an …

Hi, I'm trying to write a console program that will sort and find the median of numbers that are given in a text file. The text file can have ints or doubles.

The problem I'm having is outputting the median and the insertionSort functions. I think that they are failing because I did something wrong with either the vector or templates or both as it is my first time writing code using both of those.

Any insight is greatly appreciated.

template <typename T>
void median(const vector<T> & values) ;

template <typename T>
void insertionSort(ifstream& in_file, vector<T>& a_values);
...
	cout << "Sorted values are: " << insertionSort << endl;
	cout << "Median = " << median << endl;

Your assumption is wrong. Your insertionSort and median are functions. You never call them. You just output their respective addresses.
