```python
def check_greater(arr, num):
    for element in arr:
        if num <= element:
            return 'No, entered number is less than those in the array'
    return 'Yes, the entered number is greater than those in the array'

# Test cases
assert check_greater([1, 2, 3, 4, 5], 4) == 'No, entered number is less than those in the array'
assert check_greater([2, 3, 4, 5, 6], 8) == 'Yes, the entered number is greater than those in the array'
assert check_greater([9, 7, 4, 8, 6, 1], 11) == 'Yes, the entered number is greater than those in the array'
