getting average of an array(pointers)

[franjuk]

I need your assistance please, my code for average is giving me a negative average and instead of positive (pointers), what am i doing wrong


int main()
{
int *myIntPtr = NULL;
int arraySize = 0;
cout << "Enter array size:" << endl;
myIntPtr = new int[arraySize];
cin >> arraySize;
cout << endl;


srand(time(0));
cout << "10 random numbers between 1 and 10 generated are: ";
for (int i = 0; i < arraySize; i++)
{
*myIntPtr = 1 + rand() % (10 - 1 + 1);
cout << *myIntPtr << " ";
myIntPtr++;
}

*myIntPtr = *myIntPtr - arraySize;

int sum = 0.0;
double average = 0.0;

for (int i = 0; i < arraySize; i++)
{
sum += *myIntPtr;
average = sum / arraySize;
}

cout << "\nThe average of the elements in the array is " << average;
cout << endl;

cout << "Number of items above average: ";
int count = 0;
for (int i = 0; i < arraySize; i++)
{
if (*myIntPtr > average)
count++;
}
cout << count;


return 0;
}

You are doing cin Into array size after you allocate.
there are a few more things. But please edit your post and put code into code blocks you have the option in the right above the BOLD option
