Thread: Copy function

I am struggling at the following task:

Write a function called copy which takes the following parameters:

-Two integer arrays
-The size of the two arrays as an integer
-A threshold value as an integer

Your function should copy the values of the first array into the second array but ignore values above the given threshold.

I always get only 0 0 0 0 0 as output with my function. Does anybody now how I can fix this?

Code:

int copy(int* arr1, int* arr2, int length, int d) {
   for (int m=0; m< length;m++){
       
     int min= arr1[m];
     for(  int  i=m+1; i< length; i++){
       if (min>arr1[i]){
           arr1[i]=arr1[i-1];
       }
       else
           min=min;
   }
    arr2[m]  = min;
}
for (int n=0; n< length;n++){
    if (arr2[n] > d)
        arr2[n]=0;
    else
        arr2[n]=arr2[n];
}
}

You need to copy the values from arr1 to arr2 only if they are greater than threshold. There is no need to find the min.

Maybe sth. like this:

Code:

for (int i = 0; i < length; ++i)  {
    if (arr1[i] > d)
       // copy arr1[i] over to arr2

Thank you, it works
