    Try this code 

        int n;
    scanf("%d",&n); // input
    int sum = 0;
    int *arr = (int*) malloc(n * sizeof(int)); // using the malloc function and the memory is allocated on the heap at runtime
    for (int i = 0 ; i < n; i++){
        scanf("%d",&arr[i]);
        sum += arr[i];
    }
    
    printf("%d",sum); // printing the sum
    
    free(arr); // you have finished with the array, use free(arr) to deallocate the memory.
    arr = NULL;
      
    return 0;
}
