can I do this with if...else in spite of switch?

Question

please check the code and tell me is it possible to make a calculetor like this using if....else.

How it has to work :
if I input 2+3 (a=2,b=3) output will be 5 or if I input 4*5 output will be 20
the logic I use here is, "if input 5+7 mean a+b sum will be 'sum=a+b' and result will be 13, but its not working I don't understand how to take input this '+'... is + char?
so guys give me a good solution to make this code workable please ☺

Answer 2

You can define words
like add, sub, mult, div for operations .
I user inputs add then you specify condition a+b in if
EXAMPLE-if(input=='add')
{output=a+b;
cout<<output;
}
