Create a C++ program that can evaluate arithmetic expressions using stack with integer numbers having any number of digits. These numbers are an alternative to fixed size integers or floating point numbers that always have a maximum number of accurate digits (dependent on size of CPU register).

The program should display the input expression and the results, separated with =. If one expression is not valid, skip it and continue to process next expression

input example :

0*00000000000000000+0000000000000001

(1+2)*(1000+2000)

output example:

0*00000000000000000+0000000000000001 = 1

(1+2)*(1000+2000) = 9000
