$($Evaluate expression$)$ IN C$++$ PLEASE

Modify LiveExample $12\mathrm{.}12$ EvaluateExpression.cpp to add operators $^$ for exponent and $\%$ for modulus. For example, $3^2$ is $9$ and $3\%2$ is $1.$

The $^$ operator has the highest precedence and the $\%$ operator has the same precedence as the $*$ and $/$ operators.

When you create a new submission, you'll notice a template code that includes an implementation of the Stack class. Your task is to implement the missing parts indicated by "your code here".
