Alphabetizing a string array

[DanStirletz]

My array will contain first and last names. How do i alphabetize the names inside?

for instance names Dan Andrew Drew Vincent will be organize as such:

arr[0] Andrew, arr[1] Dan, arr[2] Drew, arr[3] Vincent..

i am currently looking at function isalpha() // is the parameter alphabetic(A..Z)

but i am puzzled at how to incorporate it into a reasonable control structure... perhaps a for loop iteration somehow involving this function?

anyway any help would be appreciated.

Show us what you have so far, so we can now where to go from

Well most names are only letters you could probably sort by the first few characters by turning the char to an int eg (int)'a' or try to use a map

[giblit]

Oh you can also try std::sort migyt be easiest

I dont have anything so far i am still trying to figure out the pseudo code.

bump

does anyone have any other suggestions?

[Ssturges]

Yes, I have one lol

So, I don't know how to explain it, so I wrote out the code, but what I have will only check for the first two letters, so for example, it will catch Dan and Drew, but not Dan and Daniel.

#include <iostream>
#include <string>

using namespace std;

int main(){
string names[]={"Drew","Andrew","Dan","Vincent"};
string temp="";
int arrSize = sizeof(names)/sizeof(names[0]);

cout << "The following is a list of names unorganized:\n";
for(int s = 0; s < arrSize; s++)
    cout << names[s]<<" ";

for (int x = 0; x < arrSize; x++){
        for(int y = 0; y < arrSize-1; y++){
            if (names[x].at(0) < names[y].at(0)){
                    temp = names[x];
                    names[x] = names[y];
                    names[y] = temp;
            }
            else if (names[x].at(0) == names[y].at(0))
                if (names[x].at(1) < names[y].at(1)){
                        temp = names[x];
                        names[x] = names[y];
                        names[y] = temp;
                }
        }
}

cout << "\n\n\nThe following is a list of names organized:\n";
for(int s = 0; s < arrSize; s++)
    cout << names[s]<<" ";

cout << endl << endl;

return 0;
}

Like I said this is just a rough draft, and will only check the first two letters. Once you understand whats going on, it shouldn't be too hard to make it check every letter for a particular string.
