Question

The input may contain numbers, valuables, arithmetic operations *, /, +, and -, as well as parentheses. The expression need not be fully parenthesized, and when parentheses are missing, the usual C++ precedence rules are used to determine the order of evaluation. Your program should allow the user to enter additional expressions until the user wishes to end the program. For a more difficult assignment, enhance your program so that the expression need not be well formed; if it is not well formed, then the user is asked to reenter the expression.

Explanation / Answer

Dear User, //Header file #ifndef H_StackType #define H_StackType #include #include using namespace std; template class stackType { private : int maxStackSize; int stackTop; Type *list; public : void initializeStack(); bool isFullStack() const; bool isEmptyStack() const; void push( const Type& ); void pop(); Type top() const; stackType( int = 20 ); ~stackType(); }; template void stackType::initializeStack() { stackTop = 0; } template bool stackType::isFullStack() const { return ( stackTop == maxStackSize ); } template bool stackType::isEmptyStack() const { return ( stackTop == 0 ); } template void stackType::push( const Type& newItem ) { if ( !isFullStack() ) { list[ stackTop ] = newItem; stackTop++; } else cout
