    Calculator in c...

    Hi, i have a exercise in c to do and i donīt really know how to start.
    I have to do a calculator that can do operations like "2+3*(3*5)-1", knowing that the operation between parenthesis has to be done first, and that the operations " * and / " are the second operations to be done etc..., like common algebra.
    If anyone knows how to do this please post because i am lost...
    thank you....

    Why don't you start by making a flowchart?
