Sort function for an array.

[JohnnyHollywood]

Hi I have the following code, in C++ that I did.

void sortit(char [5][5], int, int);
#include <stdio.h>
#include <iostream.h>

int main()
{
char names[5][5] = {{'C','a','r','l'},
{'J','a','m','e','s'},
{'J','a','n','e','t'},
{'A','l','e','x'},
{'K','a','r','e','n'}};

int i,j;

char a[10][10] = {'C'};

for(i=0;i<5;i++)
{
for(j=0;j<5;j++)
printf("%c",names[i][j]);
printf("\n");
}
sortit(names,i,j);
return 0;
}
//
//
// Modify this sortit function and place it here
//
//
void sortit(char unsorted[5][5], int i, int j)
{
//declare new arrays for multiplier and values and also temps for storage
long int values [5][2] = {{0,0},{1.0},{2,0},{3,0},{4,0}};
long int multiplier [5] = {10000, 5000, 1000, 500, 1};
long int T1, T2;

for(i=0; i<5; i++)
for(j=0;j<5;j++)
values[i][1] += unsorted[i][j] * multiplier [j];

for(i=0; i<5; i++)
for(j=i+1; j<5; j++)
if(values[i][1] > values[j][1])
{
T1 = values[i][0];
T2 = values[i][1];
values[i][0] = values[j][0];
values[j][1] = values[j][1];
values[j][0] = T1;
values[j][1] = T2;
}

for(i=0; j<5; i++)
{
for(j=0; j<5; j++)
cout << unsorted [values[i][0]][j];
cout << "\n";
}
}

This is supposed to sort the names in alphabetical order but its not, its only repeating the names in the original order. I dont know what else to do.

**** dude, what are the odds? My friend didnt finish a C++ lab last night for class, so i write it for him. Took me like 5 mins... Here is the code I used to sort a vector.

#include <iostream>
#include <vector>
#include <string>

using namespace std;
void Swap(string &, string &);
void PrintArray(vector<string> );
void BubbleSort(vector<string>&);

int main()
	{
	vector<string> Cities;
	string Temp[] = {"Los Angeles", "San Diego", "San Francisco", "Las Vegas", "Manhattan Beach", "Austin", "Redondo Beach", "Torrance"};
	int TempSize = 8;
	int temp;
	int temp2;
	for(temp = 0; temp < TempSize; temp++)
		{
		Cities.resize(Cities.size() + 1);
		Cities[temp] = Temp[temp];
		}
	cout<<"Before the Swap:"<<endl;
	cout<<"================"<<endl;
	PrintArray(Cities);
	cout<<endl;
	BubbleSort(Cities);
	cout<<"After the Swap:"<<endl;
	cout<<"==============="<<endl;
	PrintArray(Cities);
	return 0;
	}

void Swap(string &first, string &second)
	{
	string temp;
	temp = first;
	first = second;
	second = temp;
	}

void PrintArray(vector<string>Cities)
	{
	int temp;
	for(temp = 0; temp < Cities.size(); temp++)
		{
		cout<<Cities[temp]<<endl;
		}
	}
void BubbleSort(vector<string> &Cities)
	{
	int temp;
	int temp2;
	for(temp = 0; temp < Cities.size(); temp++)
		{
		for(temp2 = 0; temp2 < Cities.size(); temp2++)
			{
			if(Cities[temp2].compare(Cities[temp]) == 1)
				{
				Cities[temp].swap(Cities[temp2]);
				}
			}
		}
	}

Thanks for the code but I cant use that beacuse I have to use the code in the first function of my code that was supplied by the teacher, so it has to work with that.

geez... that code looks like **** to me, lol. Maybe if you could understand what it is im doing w/ my code, you can integrate>?

[JohnnyHollywood]

lol it may be **** but thats what he gave us to work with hehe, to make us think I guess. lol
