It runs very well in devc++ compiler. but here. i couldnt see the correct result.

Answer 1

every basic programmer can do that(you might be new idk). You should try working with more then 2 numbers. means you can do stuff like 4+5*8. or such on....
try working with string splitting or such on.
thought if it's your first program its nice

Answer 2

Please write the code in Code Playground and paste the link here. That way it's easier to read and we can actually try it out...

Answer 3

I do it as u want. but it has problem with input the numbers to calculate.
