mathematically phrase input in console
Hi
I want to give the console a mathematically phrase like this:
(3*x^2+7-2/x^6)/3^x
and then input a number and it the program can give me the answer
and also if the phrase was wrong, the program finds out for example this is wrong:
(3*x^2+7-2/x^6/3^x
because the parantheses !
tnx

It's a problem of parsing. It's not really hard. You have to read the string into a tree structure. For example, 2*x+5 could become
good luck.
+ / \ * 5 / \ 2 x |
good luck.
