I have a function declared like this

int * return_array(int * arr1 , int * arr2);

and the function is defined like this

int * return_array(int * arr1, int * arr2) { int arr_sum[5]={0}; int count = 0; do { arr_sum[count] = *(arr1+count)+*(arr2+count); count ++; } while (count < 5); return (arr_sum); }

this is how i am trying to access the returned array in the main function

int *get_arr; get_arr=return_array(arr1,arr2); cout << "Their sum is :" << endl; for (count = 0; count < 5; ++count) { cout << *(get_arr+count) << endl; }

the first sum is correct but the rest looks to be garbage values, what might be the cause?

You are returning an array from a function, but its scope does not go outside that function, so I'm sure you are seeing "garbage values".

You need to either allocate the space for arr_sum yourself in the function, or you can pass an array to be filled from the caller.

You are getting garbage as you are trying to return something local to function,

return (arr_sum);
