Answer:
The solution code is written in Python:
- def square(num):
- if type(num).__name__ == 'int':
- sq_num = num * num
- return sq_num
- else:
- return "Invalid input"
-
- print(square(5))
- print(square("Test"))
Explanation:
To ensure only certain type of operation can be applied on a input value, we can check the data type of the input value. For example, we define a function and name it as <em>square</em> which take one input number, <em>num </em>(Line 1).
Before the <em>num</em> can be squared, it goes through a validation mechanism in by setting an if condition (Line 2) to check if the data type of the input number is an integer,<em> int.</em> If so, the<em> num </em>will only be squared otherwise it return an error message (Line 6).
We can test our function by passing value of 5 and "Test" string. We will get program output:
25
Invalid input

The answer to this question is: CE
Calculator will memorize the input that you made from previous calculation until you press the = button.
CE stands for clear data, which means that by pressing this, you will eliminate the calculation from previous effort and start the new calculation on a blank state
