what is my wrong?

Question

Implement function maxabsinlst(lst), which returns the maximum absolute
value of the elements in the array.
For example, given a array lst: [-19, -3, 20, -1, 0, -25], the function
should return 25.
MY ATTEMPT
long arr[1000];
int max;
int absoluteValue;
for(int i = 0; i < 6; i++){
cin>>arr[i];
if(arr[i]<0){
absoluteValue = arr[i] * (-1);
if (arr[i] > max)
max = arr[i];
if(absoluteValue>max)
cout << absoluteValue << endl;

else {
cout << max << endl;
}
}
}
