C++ Arrays:invalid conversion from int to int*?

[rvbplayer123]

Writing a programs that get integers from a file, reads to arrays, sorts the arrays in ascending order and outputs it. But im having trouble with the sorting function: void bubbleSort

const int MAX_NUMBERS = 25;

// function protoypes go here

int main()
{
 int x[MAX_NUMBERS];
 string file1, file2;

 getUserInput(file1, file2);
 downloadArray(file1,x);
 bubbleSort(x);
 
 outputArray(file1, file2,x);

system("pause");
return 0;

}

void getUserInput( string &inputfile, string &outputfile )
{

cout << "Enter input file name: ";
cin >> inputfile;
cout << endl;

cout << "Enter output file name: ";
cin >> outputfile;

}
void downloadArray ( string &inputfile, int array[MAX_NUMBERS])
{
ifstream input;


input.open(inputfile.c_str() );


while(input >> array[MAX_NUMBERS])
{
cout << array[MAX_NUMBERS] << " ";
}


input.close();
}

int bubbleSort(int array[MAX_NUMBERS])
{
int i, j;


swapNumbers(array);
for(i = 0; i <= (MAX_NUMBERS - 1); i++ )
{
for(j = i+1; j <= MAX_NUMBERS; j++ )
{
int temp;
if(array[i] > array[j])
{
temp = array[i];
array[i] = array[j];
array[j] = temp;
}
}

}
for(i = 0; i <= MAX_NUMBERS; i++ )
{
cout << array[i] << endl;
}
return i;
}
int swapNumbers(int array[MAX_NUMBERS])
{
int i;

for(i = 0; i <= MAX_NUMBERS; i++ )
{
cout << "Enter a number: ";
cin >> array[i];

}
return i;


}
void outputArray( string &inputfile, string &outputfile, int array[MAX_NUMBERS] )
{
ifstream input;
ofstream output;
int index,y;

input.open(inputfile.c_str() );
output.open(outputfile.c_str() );

index = 0;
while(input >> array[index++])
{
}

int arrayLength = index - 1;

for (int i = 0; i < arrayLength; ++i)
{
output << bubbleSort(array[i]) << " ";
if( y >= 10)
{
output << "/n" << endl;
y = 0;
}
y++;
}

output.close();

}

I did not see all your code because it will be enough to point out that this function is invalid

void downloadArray ( string &inputfile, int array[MAX_NUMBERS])
{
ifstream input;


input.open(inputfile.c_str() );


while(input >> array[MAX_NUMBERS])
{
cout << array[MAX_NUMBERS] << " ";
}


input.close();
}


You are trying to read all file data in one element of the array with index MAX_NUMBERS and I am afraid that this index is beyond the acceptable range of ndexes for the array.
