Sorry, there is no integral calculus built-in function in the C++ Standard Library.

Take a look at this article: http://www.codeproject.com/KB/recipes/FastNumericalIntegration.aspx ("Fast Numerical Integration") which shows a very elegant approach to numerical integration using templates. The result can be as simple as
class DemoFunction
{
public:
    double operator()(double x) const
    {
        return exp(-x/5.0)*(2.0 + sin(2.0*x));
    }
};

DemoFunction f;
int evaluations;
double errorEstimate;
double integral = DEIntegrator<DemoFunction>::Integrate
        (f, 0, 10, 1e-6, evaluations, errorEstimate);
std::cout << integral << ", " << errorEstimate 
          << ", " << evaluations << "\n";

Hi phoffric,

                    Will this " http://sourceforge.net/projects/gattmath/ " solve the complete requirements of Integration.

This site grants you permission to download this book:
     http://astronu.jinr.ru/wiki/upload/d/d6/NumericalRecipesinC.pdf

You can copy the c code from it, and with the lengthy explanations, you can customize it for your needs.

(My mistake about the previous links - they are not for C/C++.)
