It is not a magic, of course, logically explainable effects the radio waves. When the devices use WiFi signals to connect to the Internet then these signals are sent with the radio waves and despite all the advanced features of wireless interference can happen.

including how it can be stored and what types of operations we can perform. For example, we can write a program that squares num

ASHA 777 [7]

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 square which take one input number, num (Line 1).

Before the num 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, int. If so, the num 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:

Invalid input
