// main method here where passing in array
// in main method or whatever method is using fxn, make sure to free() memory

//int * ptr_2 = add_one(ptr, size);
//free(ptr_2);
//good practice to also set ptr_2 = NULL;

// dynamically allocating ptr_2 allows us to use the array result in different instances outside of the function itself
