Dev C++ confusion

[MJFiggs]

I have been working on this problem so much, I have started to think in Binary.
what I am supposed to do is put User defined numbers in acending order.
Here is what I tried.
(please dont laugh)

#include <iostream>
#include <iomanip>
#include <vector>
using namespace std;

void testSort(int [], int);
void testShow(int [], int);

int main()
{
     int count=0;
     int testNum=0;
     const int SIZE=50;
     vector<int> test(SIZE);
     int Avg1=0;
     double Avg2=0;
     
     cout <<"how many tests will you be entering? ";
     cin >> testNum;
     
     for (count=0; count < testNum; count++)
     {
      cout << "enter score for test "<< count+1<<" : ";
      cin >> test[count];
      Avg1+=test[count];
     }
     Avg2=static_cast<int> (Avg1)/testNum;
     
     testSort(test, SIZE);
     
//this is to show the grades in acending order

     for (int count = 0; count < testNum; count
         {
          cout<< test[count] << endl;
         }
     
     cout << "your average score is: " << Avg2<<endl;
      
     
     system("pause");
     return 0;
}

void testSort(int test[], int SIZE)
{
     int startScan, minIndex, minValue;
     
     for (startScan = 0;startScan < (SIZE-1); startScan++)
     {
         minIndex = startScan;
         minValue = test[startScan];
         for(int count = startScan +1; count <SIZE; count++)
         {
          if (test[count]<minValue)
             {
                  minValue = test[count];
                  minIndex = count;
             }
          }
          test[minIndex] = test[startScan];
          test[startScan] = minValue;
     }
}

if this looks rediculous, it is because I have tried everything I can think of.
Please help, thank you for your time

Here is how I code that function.

void testSort(int test[], int SIZE)
{
    for (startScan = 0;startScan < (SIZE-1); startScan++)
    {
         for(int count = startScan +1; count <SIZE; count++)
         {
              if (test[startScan] < test[count])
             {
                  int temp = test[startScan];
                  test[startScan] = test[count];
                  test[count] = temp;
             }
          }
     }
}

I tried that and got this error message
cannot convert `std::vector<int, std::allocator<int> >' to `int*' for argument `1' to `void testSort(int*, int)'

[Ancient Dragon]

You get that error because you are passing a vector and the function wants an int array. Not the same thing. So just change the function to this:

Note, this doesn't need the second parameter SIZE because vectors know their size.

void testSort(vector<int>& test)
{
    for (int startScan = 0;startScan < (test.size()-1); startScan++)
    {
         for(int count = startScan +1; count < test.size(); count++)
         {
              if (test[startScan] < test[count])
             {
                  int temp = test[startScan];
                  test[startScan] = test[count];
                  test[count] = temp;
             }
          }
     }
}

what exactly is "ubt?" I can't find it in my book.

[Ancient Dragon]

what exactly is "ubt?" I can't find it in my book.

I have no idea either. Where did you see that ?

[MJFiggs]

here
void testSort(vector<int>& test)
{
for (ubt startScan = 0;startScan < (test.size()-1); startScan++)
}

[Ancient Dragon]

It is my mispelling of int. I hit the wrong keys and didn't notice it.

[MJFiggs]

ah, that makes sense

it still is not working, so I was thinking, might the atoi finction work to solve this?

[Ancient Dragon]

worked for me. delete all references to SIZE and call resize() after you know how many elements are to be entered.

how many tests will you be entering? 5
enter score for test 1 : 5
enter score for test 2 : 3
enter score for test 3 : 1
enter score for test 4 : 2
enter score for test 5 : 4
5
4
3
2
1
your average score is: 3
Press any key to continue . . .

int main()
{
     int count=0;
     int testNum=0;
     vector<int> test;
     int Avg1=0;
     double Avg2=0;
     
     cout <<"how many tests will you be entering? ";
     cin >> testNum;
     test.resize(testNum);
     for (count=0; count < testNum; count++)
     {
      cout << "enter score for test "<< count+1<<" : ";
      cin >> test[count];
      Avg1+=test[count];
     }
     Avg2=static_cast<int> (Avg1)/testNum;
     
     testSort(test);
     
//this is to show the grades in acending order

     for (int count = 0; count < testNum; count++)
     {
          cout<< test[count] << "\n";
     }
     
     cout << "your average score is: " << Avg2<<endl;
      
     
     system("pause");
     return 0;
}

void testSort(vector<int>& test)
{
     
     for (unsigned int startScan = 0;startScan < (test.size()-1); startScan++)
     {
         for(unsigned int count = startScan +1; count < test.size(); count++)
         {
          if (test[startScan] > test[count] )
             {
                 int temp = test[startScan];
                 test[startScan] = test[count];
                 test[count] = temp;
             }
          }
     }
}

Thank you Ancient, your programming knowlege has saved yet annother hide.
the Bunny below thanks you too.
