Problem Statement:
You
are a software developer, and you have to develop a program in C++ that acts as
a simple calculator for performing basic arithmetic operations using switch
statements. Your name and student id must be displayed before a menu of
options. No need to prompt student id and name from user, you can just hard-code
it.
You have to perform
the following operations in the program.
- Addition
- Subtraction
- Multiplication
- Division
- Exit
Step by step procedure:
- First, you
need to hard-code your VU student id along with your name, and it should
be displayed at the top as shown in the output screenshot given below.
- Then you have
to create a menu, that will ask the user, what operation they want to
perform? Like addition, subtraction, multiplication, or division, or if
they want to quit already? (See output screenshot for the menu).
- After
selecting the operation, your code should work in such a way that the user
can add, subtract, multiply or divide as many numbers as they want to. For
example, your code should ask the user about how many numbers do you want
to add? If a user mentions 5, then it should be able to add all of them.
Same for the other operations as well.
- In case of
division, if a user wants to divide three numbers altogether, then first
number entered will be considered as a numerator and second number would
be considered as denominator, now in the second iteration, the result of
first two numbers division will be considered as numerator and the third
number which a user is going to enter, will be considered as denominator.
For example: Let’s say, a user entered 3 numbers for division, those
numbers are 9,
3 & 3. In the first iteration, 9
will be considered as numerator while 3 will be a denominator i.e. 9/3,
after dividing those numbers i.e. 9/3=3 we got
3 as a result. Now in the second
iteration, the result 3 would be considered as
a numerator (that we got in the first iteration) and our last entered
number 3 would be considered as a denominator, from which we got a result
3/3=1, you can also check the output screenshot for how it
should be displayed.
- Also, in case
of division, you should handle floating point numbers as well. And your
code should not let the user divide any number by zero.
- In case of subtraction, you should handle
negative numbers as well. For example, if a user enters 1,2 & 4 (as shown in the output screenshot below) then it
should work in such a way, that in the first iteration 1-2= -1 would be executed and in the second iteration
the result of first iteration i.e. -1 – third entered
number i.e. 4, should be executed
i.e. -1-4 = -5
- Ensure that the program executes at least once and continues to execute until the user chooses to exit the program.
