C++ Question

I am trying to calculate the float using pointer variable, but I am getting an error that I cannot convert 'float*' to 'int*' in initialization. Any ideas how I would go on converting a float to an integer? Thanks a lot.

`int main()`

{

float arr[SIZE]={1.1,2.2,3.3,4.4,5.5};

int sum, average, avg=0;

int* end=arr+SIZE;

for(int* ptr=arr; ptr<end; ptr++)

{

sum+= *ptr;

avg = average/sum;

}

cout << "The sum is " << sum;

cout << "The average is " << avg;

}

you can solve it by: append 'f' to each value in the array also only calculate the average outside the loop no inside so in your program you are calculating avg after each sum!!

```
const int SIZE = 5; // or #define SIZE 5 // I recommend using const
float arr[SIZE] = {1.1f, 2.2f, 3.3f, 4.4f, 5.5f};
float sum = 0, avg = 0;
float* end = arr + SIZE;
for(float* fPtr = arr; fPtr < end; fPtr++)
sum += *fPtr;
avg = sum / SIZE;
cout << "The sum is " << sum << endl;
cout << "The average is " << avg << endl;
```
