CODING CHALLENGES #1 !! Calculator with one input

Question

Thank you @Agus Mei for this great idea! What if we do coding challenges like @Agus is making his/her quizzes? Allright! My first challenge is:

A calculator that takes needs one input like 2 * 2... Then the computer should assign the first number to a variable, second one to the operator and third one as a number...

NO GOOGLE OR STACKOVERFLOW!!

I've done mine in Python!!

Made completely from scratch with basic stuff

Answer 4

@Leandro try to do it yourself. If there'll be errors post question and people will help u. If somebody else does that for you it gives you nothing in term of experience.

Answer 5

@Leandro tasks 1-4, 6-7, 9 "for" loop
task 5 "for" loop + array
tasks 8, 10 if + "for" loop

Answer 6

I have quite the something here, it would just require tweaking to get user input into appropriate arrays. Will submit if time permits.

Answer 7

@MrCoder This is what I am planning to do... The next one is coming soon :)

Answer 8

#uh guys...
eval(input())
#you literally only need one line to do this in python

Answer 9

You need to insert it here after you finish!

Answer 10

@Sahaj Yes, you can put more operators.

You will have to think what if the user inputs something like 9*7, without spaces in between

Answer 11

@Hatsy But you will have to start from scratch

Answer 12

@Mr Coder... It has to be error-free. Operations without whitespaces won't work...
@Wen Qin It had to be done from scratch
@Heng Congratulations mate, you won!!

Answer 13

@Wen The challenge is over, as you can see we already have a winner... I am not going to post the solution until we get the best answer.
