Please help, sorting related

Hi all,
I've been working on a program that is supposed to sort and array in descending order using the bubble sort mechanism, but I just can't seem to get it. I've looked up some sites on the internet , and I searched this board but I still didn't get to anything. Below is the code I have reached to:

----------------------------------------------------------------------------
#include <iostream.h>
#include <fstream.h>
int main ()
{
ifstream inFile ("insort.txt" , ios::in);

int i, vector[20], max, dim,temp,k,mpos;

inFile>>dim;

for (i=0 ; i<dim ; i++)
inFile>>vector[i];


for (i=0 ; i<=dim-1 ; i++)
for (k=i; k<=dim ; k++){
if (vector[k]>max){
max=vector[k];
mpos=k;
}

temp=vector[mpos];
vector[mpos]=vector[i];
vector[i]=temp;
}

for (i=0 ; i<dim ; i++)
cout<<vector[i]<<endl;



return 0;

}

------------------------------------------------------------------

I can't figure out what's wrong with it.

Help is most appreciated.
Thank you.

This is a bubblesort that I wrote for one of my projects.
it is written for Dev C++ so will probably need modifying.
You will also need to modify the method of inputting your data into your arrays.

Hope this helps... :)

#include <stdio.h>
#include <iostream.h> // include any header files you might need
#include <fstream.h>
#include <stdlib.h>

int main(int argc, char *argv[]) // 'int main()' will do for most compilers.
{

bool swapped=false; // flag.
int i, temp;
int v[5] = {0,1,6,4,3}; // numbers to be sorted
do
{
swapped = false;// reset swapped flag.
for(i=0;i<4;i++) // only do to size of array - 2
{
if(v[i]>v[i+1]) // change this to '<' for descending sort
{
temp=v[i];
v[i]=v[i+1]; // Swap them!
v[i+1]=temp;
swapped = true; // set swapped flag
}
}
}while(swapped); // do...while loop exits when no more swaps have been made, ie the array is sorted.

for(i=0;i<5;i++)
{
cout<<v[i]<<" "; // print it out to verify that it works.
}
system("pause"); // only required for Dev-C++

return 0;
}

Thank you very much Homer, you made my day!! :) :)
