1.) You are designing a simple calculator program for young children to use. Right now, if they do something that the program didn’t expect, a message appears that reads, “User input deemed invalid.” What changes could you make so that the message would be more suitable for this audience? 2.)In what real-life situations might you want to use the modulus operation in a program?
3.) It sure would be a lot simpler if there were only one type of variable, but programming languages such as Python have multiple types. Why do you think this is?
4.)In what situations might you want to create a variable with the value of NULL?
5.) Can you think of a situation where you might want to change the data type of a variable?
