Thread: I need help

Code:

void ShuffleExchangeSort(mainStruct& mouse)
{
  	bool bvar;					//this variable will be used to indicate if the list is ordered.
    //Some looping structure.
    {
      	bvar=true;
    }
}

When i compare the times would i just use a > or< or would i use some sort of swap function?
Wow this is too advanced for me...

I have come up with this conclusion for the sort function:

Code:

void ShuffleExchangeSort(mainStruct& mouse)
{
  	int k;
  	bool bvar;					//this variable will be used to indicate if the list is ordered.
    
      	k=0;
      	bvar=true;
        
	while(k<N-1 && bvar)
    {
      bvar=false;
      k++;
      for(int i=0; i<n-k; j++)
      {
        if(list[i].number > list[i+1].number)
        swap(list,i,i+1);
        bvar=true;
      }
    }
}

I looked at a piece of code from class and am getting errors, do i need other functions?

Here is my most up to date piece of code:

Code:

#include <iostream>	//for console IO
#include <fstream>	//for file IO
#include <string>	//for the string class
using namespace std;

struct mainStruct		//this holds our data
{
	string name;	//it contains a name
	string time;	//and a time
};
struct teamStruct		//this holds our data
{
  	string team;	//it contains a name
};

void ReadMainData(mainStruct& mouse);	//read in the data
void ReadTeamData(teamStruct& cat);		//read in the data
void ShuffleExchangeSort();				//sorts the information

int number;
const int Size=50;


int main()
{	
	//std::ofstream out;	//you never used this...
	mainStruct mouse;	//instantiate a struct
    teamStruct cat;		//instantiate a struct
	//you do realize that after this runs, you'll be left with the last name
	//in the data file, right?
	ReadMainData(mouse);	//you don't specify datatype when calling
	//cout<<mouse.name;	//output a name
    ReadTeamData(cat);
	
	return 0; 
}

void ReadMainData(mainStruct& mouse)
{
	fstream input("main.run");	//open the file for reading
	char*line=new char[25];		//create space for a char*
	
	while(input.get(line,25))		//take in the 25-char name
	{
		mouse.name.assign(line);	//assign the name to the string in the struct
    	input>>mouse.time;		//take in and assign the time to the struct
		input.ignore(32000,'\n');	//ignore up to the next newline
        cout<<mouse.name<<" "<<mouse.time<<endl;
  	}

	input.close();				//close the input file
	delete[]line;				//free the memory from the char*
  	cout<<mouse.time << endl;	//ouptut the time (consider relocating this)
}

void ReadTeamData(teamStruct& cat)
{
  	fstream input("teams.dat");	//open the file for reading
    char*line=new char[31];		//create space for a char*
    
	while(input.get(line,31))		//take in the 31-char name
    {
      cat.team.assign(line);	//assign the name to the string in the struct
      		getline(input,cat.team,' ');	//take in and assign the team name to the struct
      input.ignore(32000,'/n');	//ignore up to the next newline
      cout << cat.team <<endl;
    }
    
	input.close();					//close the input file
    delete[]line;					//free the memory from the char*
    cout<<cat.team<<endl;			//output the team
}

void Swap(mainStruct mouse[Size], int Rec1, int Rec2 )
{
mainStruct Temp;

Temp = List[Rec1];
List[Rec1] = List[Rec2];
List[Rec2] = Temp;
}

void ShuffleExchangeSort(mainStruct& mouse)
{
  	int k;
    int n;
  	bool bvar;					//this variable will be used to indicate if the list is ordered.
    
      	k=0;
        n=100;
      	bvar=true;
        
	while(k<n-1 && bvar)
    {
      bvar=false;
      k++;
      for(int i=0; i<n-k; i++)
      {
        if(mouse[i].time > mouse[i+1].time)
        {
        swap(mouse,i,i+1);
        bvar=true;
        }
      }
    }
}

I am getting these errors though:
