    how to sort an array

    I need to sort an array of strings alphabetically in c++ and I have no idea how to do this...

    I would prefer to do this without pointers or qsort or std::sort

    Thanks,

    Dustin

    you could try this:


    void SelectionSort(apvector<apstring>&v){
    n=v.length();

    while(n>1){
    //find largest element
    for(iMax=0, i=1; i<n; i++)
    if(v[i]>v[iMax])
    iMax=i;

    //swap
    temp=v[n-1];
    v[n-1]=v[iMax];
    v[iMax]=temp;
    }
    }

    convert the strings to all lower case or all upper case unless you feel A is different from a. Then use strcmp() to comare c_style strings, swapping the two strings if appropriate. If you are using STL style strings or apstrings or TStrings or CStrings then you can use a logical operator to do the comparison.
