i really need help!!!
i am a noob, just getting started in c++
and i need help sorting my array.
please don't suggest me std::sort because i don't really know how to use those! sorry i am such a noob,

``````{
do{
cout <<"enter score " << i << ": ";
cin >> scores[i];
if((scores[i] <= 0)||(scores[i] >=100))
cout << "invalid score\n";
}while((scores[i] <= 0)||(scores[i] >=100));
//this is where i input the scores.

void SortNumbers()
{
cout <<"the sorted list is ";
for(i= 0; i <scores[9]; i++)
{
if(scores[i]>scores[i+1])
Swap(scores, i);
cout << scores[i] << " ";
}
cout << endl;
}

void Swap(int scores[], int i)
{
int temp;
temp = scores[i];
scores[i]=scores[i+1];
scores[i+1] = temp;
}
//this is the part i am having trouble with
``````

the swap my teacher told me does not work.... it may be just me, but i can't get it to work,
thank you!!!

hi,

for(i= 0; i <scores[9]; i++)

as 'i' is index,its value should be 0 to 8 if size of array is 10, so it should be witten like:
for(i=0;i<9;i++)
i find this mistake only.i dont think there is any mistake in swap function.

You should never do input/output in a function, unless it is an input/output function. Otherwise, your sort function is fine. Here is my sort function:

``````void Sort(int Array[], int NumUsed)
{
int temp, i, j;

for (i = 0; i < NumUsed - 1; i++)
{
int Smallest = i;

for (j = i + 1; j < NumUsed; j++)
{
if (Array[j] > Array[i])
{
Smallest = j;
}
}

temp = Array[i];
Array[i] = Array[j];
Array[j] = temp;
}
}``````

thanks, but how to do bubble sort this?

also, i am keep getting 0 for my highest number, why?

## firstPerson 761

For bubble sort all you have to do is blindly swap :

``````int A[5] = {5,3,1,7};

//bubble sort
for(int i = 0; i < 5; i++){
for(int j = i+1; j < 5; j++)
if(A[i] > A[j] ) std::swap(A[i],A[j]);
}``````
