How to directly add basic calculation signs in c programming?

Question

I was just trying to program in c. I'm using cell phone rather than pc. I wanted program calculator, where you can directly give input like 2+3 which will give answer 5 rather than preselecting the operator. I can initialize two float or integer for number input using scanf to call the user input. BUT HOW CAN I MAKE THAT OPERATOR USER INPUTABLE? Please, if anyone have good idea on it, it will be highly appreciate. May you have simple solution, but I being beginner had a lot of problems on it. Your help is highly appreciated.

Answer 1

You can write the input statement as follows-

float x,y;
char op;
scanf("%f%c%f, &x, &op, &y);

This will automatically break up 5+2 into individual groups.
Make sure you dont include spaces in the input format.
It shouldn't be something like 5 + 2. Avoid spaces.
