sorting algorithm not working correctly

[System_Error]

I can't seem to get this sorting alogorithm to work:

#include <iostream>


void sortAssending(int nums[], int size);

int main()
{
    int nums[] = {175,167,160,164,183,187,188,179,176,175,
                  169,175,176,178,165,160,173,165,187,178};
    sortAssending(nums, 20);
    for (int i=0; i<20; i++)
    {
        std::cout << nums[i] << std::endl;
    }
    
    system("PAUSE");
}

void sortAssending(int nums[], int size)
{
     for (int start=0; start<size; start++)
     {
         for (int end=size-1; end>=0; end--)
         {
             if (nums[start] > nums[end])
             {
                 int temp = nums[start];
                 nums[start] = nums[end];
                 nums[end] = temp;
             }
         }
     }
}

It seems to do everything right except the very end. Can anyone spot the problem?

template <class T>
void bubble(T *x, int n)
{
    int i, j;
    for (i = 0; i < n-1; ++i)
           for (j = i+1; j > 0; --j)
            if (x[j] < x[j-1]) swap(x[j], x[j-1]);
} 

See if that works for you. I must warn you. Bubble sorting is so slow that it's practically useless.

Minor point: it's "ascending".

void sortAssending(int nums[], int size){
     for (int start=0; start<size; start++){
         for (int end=size-1; end>=0; end--){
             if (nums[start] > nums[end]){
                 int temp = nums[start];
                 nums[start] = nums[end];
                 nums[end] = temp;
             }
         }
     }
}

Try changing the 'end >= 0' to 'end > start'
Then, it becomes just a weird form of selection sort in disguise:
For each start (0 -> size - 1), assuming the first #start objects are sorted:
Put the next smallest into nums[start]. This sorts the first #start + 1 objects, and completes the inductive proof.
