I just need code in C++ language

Design and create a C++ class to convert a string representing a positive integer or positive decimal value into the long int and double numeric types. If the string value represents a decimal value, the converted integer version will be truncated. If the string value represents an integer, the converted decimal value will have a decimal portion of zero.

Your design must use a character stack class in your conversion. You may use two stacks for the conversion if you wish. Your stack class must be based on the integer stack class developed in class (see handout). Your convert to numeric class should have member functions for the following tasks: an overloaded constructor that accepts the string to convert a convert member function that accepts a string and returns a boolean success status a getIntValue member function that returns the converted value as a long int a getDecValue member function that returns the converted value as a double Create a driver program to demonstrate your class. The driver will prompt the user and accept a string representing a positive integer or decimal, then use your class to convert it. Finally, demonstrate the converted value is useable with any type specic operation, both as a long int and double. A Design Document is required for this assignment. The Algorithm portion of your design document must describe both the conversion class and the driver program. The Flowchart portion of your design document should only depict the conversion process from string to numeric.
