Write a program that prompts the user to enter an equation in the form of 10 5, or 10-5, or 1*5, or 13/4, or 13%4. The program s

grandymaker [24]

Answer:

equation = input("Enter an equation: ")
if("+" in equation):
operands = equation.split("+")
result = int(operands [0]) + int(operands[1])
print(operands[0] + "+" + operands[1] + "=" + str(result))
elif("-" in equation):
operands = equation.split("-")
result= int(operands [0]) - int(operands[1])
print(operands[0] + "-" + operands[1] + "=" + str(result))
elif("*" in equation):
operands = equation.split("*")
result = int(operands [0]) * int(operands[1])
print(operands[0] + "*" + operands[1] + "=" + str(result))
elif("/" in equation):
operands = equation.split("/")
result = int(operands [0]) / int(operands[1])
print(operands[0] + "/" + operands[1] + "=" + str(result))
elif("%" in equation):
operands = equation.split("%")
result = int(operands [0]) % int(operands[1])
print(operands[0] + "%" + operands[1] + "=" + str(result))

Explanation:

The solution code is written in Python 3.

Firstly prompt user to enter an equation using input function (Line 1).

Create if-else if statements to check if operator "+", "-", "*", "/" and "%" exist in the input equation. If "+" is found (Line 3), use split method to get the individual operands from the equation by using "+" as separator (Line 5). Output the equation as required by the question using string concatenation method (Line 6). The similar process is repeated for the rest of else if blocks (Line 7 - 22).

solmaris [256]

Answer:

B. Least privilege

Explanation:

The principle of least privilege an important principle in computer security.
It limits the access rights for users and only grant them with the rights that are sufficient for them to perform their required task.
For example a user is granted privilege to execute a file or manipulate data or use only the resources that are required for them to perform a particular task.
This principle can be used only to limit and control access rights to system resources and applications.
The least privilege is beneficial as it reduces the risk of unauthorized access.
For example a user whose task is data entry and has nothing to do with controlling access or granting access rights to users, will only be allowed to enter data to the DB by the principle of least privilege.
