Question

How do you sort an array of strings in C++ that will make this happen in this order:

mr Anka

Mr broWn

mr Ceaser

mR donK

mr ålish

Mr Ätt

mr önD

//following not the way to get that order regardeless upper or lowercase and å, ä, ö
//in forloop... 
string handle;
point1 = array1[j].find_first_of(' ');
string forename1(array1[j].substr(0, (point1)));
string aftername1(array1[j].substr(point1 + 1));
point2 = array1[j+1].find_first_of(' ');
string forename2(array1[j+1].substr(0, (point2)));
string aftername2(array1[j+1].substr(point2 + 1));
if(aftername1 > aftername2){
    handle = array1[j];
    array1[j] = array1[j+1];
    array1[j+1] = handle;//swapping
}
if(aftername1 == aftername2){
    if(forname1 > forname2){
        handle = array1[j];
        array1[j] = array1[j+1];
        array1[j+1] = handle;   
    }
}

Answer 1

Tables and transformations.

I would first convert the string to either all uppercase or all lowercase:

#include <cctype>
#include <algorithm>
#include <string>

std::string test_string("mR BroWn");
std::transform(test_string.begin(), test_string.end(),
               test_string.begin(),
               std::tolower);

Next I would check for exceptions or use an equivalency table. If the character in question is in an array of exception characters, then use an equivalency table.
