Python has some powerful functions, like the math expression evaluator eval(). You can embed this function and others in your Development C++ code. All you need to do, is to download and install the free Python Development Pak and feed the Python code in the form of a string to the interpreter. Your executable file will work as long as there is access to the Python24.dll (part of the pak). Looks to me like you could use a Python program to create this C++ program embedding a Python code file. A Python to C++ translator is born!
Dev-C++ and Python
// needs the Python-2.4.1.DevPak installed into Dev-C++, download from:

#include <iostream>
#include <string>
// run the Python interpreter included in eg. Python24.dll
// this macro saves on typing!
#define PY PyRun_SimpleString(input.c_str())
using namespace std;
// include the Python library header
extern "C" {
#include <python2.4/Python.h>
}
int main()
{
// initialize Python
Py_Initialize();
// optional - display Python version information
cout << "Python " << Py_GetVersion() << endl << endl << endl;
string input;
// use the Python eval() function to evaluate a math expression
input = "str1 = '3 * 4 + 2'"; PY;
input = "print 'eval(%s) = %s' % (str1, eval(str1))"; PY;
// 50 dashes for the fun of it
input = "print '-' * 50"; PY;
// more eval() stuff
input = "str2 = '355/113.0 * 4 + 7'"; PY;
input = "print 'round(eval(%s), 2) = %s' % (str2, round(eval(str2), 2))"; PY;
// finish up and close Python
Py_Finalize();
cin.get(); // console wait
return 0;
