    Question How To SORT DATA In Database With C/C++?

    There are many books on database programming available for VB 6 & Java in the market but I could not find any for C or C++.

    I would like to know how to sort data from database created with Microsoft Access and display it to the screen.

    I have the source code for sorting from Deitel & Deitel's book. I hope any C++ expert out there could tell me how to sort the 99 numbers if the data is in Microsoft Access database instead of the source code.

    If you have any source code on searching and sorting the database with C or C++, or if you know any online resources or tutorial, I would appreciate it very much if you could post it here.

    Thanks.

    Code:
    #include<iostream>
    using std::cout;
    using std::endl;
    using std::ios;
    #include<iomanip>
    
    using std::setw;
    using std::setiosflags;
    using std::setprecision;
    
    void mean(const int[], int);

    int main()
    {
    	const int responseSize = 99;
    	int frequency[10] = {0}, 
    		response[responseSize] =

    You use your favourite database connector and send an SQL query to retrieve the data sorted.

    MS Access is not a general C++ issue.
