Heres my hack at alphebetizing any old string


#include <cstdio>
#include <string>
#include <iostream>

using namespace std;



void main()
{
	string s1 = "hi there";
	bool changes = true;
	char c;
	int a;

again:
	changes = false;
	a = 0;
	while(a < s1.size() - 1)
	{
		
		if(s1.at(a) > s1.at(a+1))
			{
				changes=true;
				c = s1.at(a+1);
				s1.at(a+1) = s1.at(a);
				s1.at(a) = c;
			}
			a++;
		cout << s1 << "\n";
	}

	if(changes) goto again;

	cout << "s1=" << s1 << "\n";


}

I want to see how else it can be done, preferrably in a more elegant way, as I think the way I did it is probably horrible. -Jason

Here's mine [smile]

#include <algorithm>#include <string>#include <iostream>using namespace std;int main(){   string s1 = "hi there";   sort(s1.begin(), s1.end());   cout << "s1=" << s1 << "\n";}
