Thread: Help A Newbie Sort, Please :)

Code:

#include<iostream>
#include <string>
#include <sstream>
using namespace std;

int main(){
int i=0, ii = 0, maxMovies;
string input;

//command to prompt user for amount of movies
cout<< "How many movies do you want to add? ";
getline(cin,input);
//end command to prompt user for amount of movies

//set up loop situation to take the input from user and transfer it to X
stringstream(input)>> maxMovies;

//sets up array of however many X is with a limit of 50 characters
char movies[maxMovies][50];
char ratings[ii][50];

system("cls");


while(i< maxMovies){
cout <<"Enter Movie # "<<i+1<<" : ";
cin.getline(movies[i], 50);
cout <<"Enter Rating: ";
cin.getline(ratings[ii], 50);
system("cls");

i++;
ii++;
}

system("cls");

              cout << "Results Are As Follows :" << endl << endl;
                   i = -1 ;
                   ii = -1;
              for ( int z = 0; z <= maxMovies - 1;)
              {
                    i++;
                   ii++;
                   cout << movies[i] << endl << "Rating : " << ratings[ii] << endl << endl;
                   z++;
                   }

   
system("pause");
return 0;
}

is my actual code and what i am trying to do is get a user to enter a number for how many movies they want to add, then ask them the movie name followed by what they would rate it, it does that and prints it back to the user but now i need to figure out how to get the program to sort the movies alphabetically if the user wants or by ratings in descending order, so if someone could show me a newbie friendly way to do that i would be most appreciative.

Yeah i am trying to understand that site and am trying to implement my array ( ratings ) where it has sort( movies, movies + array_size); and still am getting errors hah oh well thanks for the help suppose ima have to look towards getting a c++ for dummies book hah.

Don't discourage yourself. Slow and steady wins the race.

Not really discouraged just sad that I am unable to find a simple way to do this then when I finally get it I will be kicking myself lol.

Code:

#include<iostream>
#include <string>
#include <sstream>
#include <algorithm>


using namespace std;

int main(){

    
     
int i=0, ii = 0, maxMovies;
string input;

//command to prompt user for amount of movies
cout<< "How many movies do you want to add? ";
getline(cin,input);
//end command to prompt user for amount of movies

//set up loop situation to take the input from user and transfer it to X
stringstream(input)>> maxMovies;

//sets up array of however many X is with a limit of 50 characters
char movies[maxMovies][50];
char ratings[maxMovies][50];
int count[maxMovies];

system("cls");


while( i < maxMovies ){
                      
                       cout <<"Enter Movie # "<<i+1<<" : ";
                     
                       cin.getline(movies[i], 50);
                     
                       cout <<"Enter Rating: ";
                      
                       cin.getline(ratings[ii], 50);

                       system("cls");


                       i++;
                       ii++;
                       
}



int z = 0;
char placeHolder[]="Place Holder";
if ( ratings[z] < ratings[z + 1] )
{
     
        strcpy ( placeHolder[] , ratings[z] );
        strcpy ( ratings[z] , ratings[z+1] );
        strcpy ( ratings[z+1] , placeHolder[] );
        z++;
}
//test string copies from ratings[z] to ratings[z+1]
//int z = 0;
//strcpy (ratings[z + 1], ratings[z]);





system("pause");


system("cls");
cout << "Results Are As Follows :" << endl << endl;

i = -1 ;
ii = -1;


for ( int z = 0; z <= maxMovies - 1;)
{
      i++;
      ii++;
      cout << movies[i] 
           << endl 
           << "Rating : " 
           << ratings[ii] 
           << endl 
           << endl;

           z++;
}

   
cin.get();
return 0;
}

heres my code and as you can see i am struggling with strcpy so any assistance please

well now i have it as

Code:

char string[50]="place holder";
     int zz = 0;
if ( ratings[zz] < ratings[zz + 1] )
{

        strcpy (string, ratings[zz]);
        strcpy (ratings[zz], ratings[zz+1]);
        strcpy (ratings[zz + 1], string);
        zz++;
}

well if i understood your suggestion and when i change code in mine if it worked id be happy but i am simply a newber with a book learning and that is way beyond me at the second but i have got my code to semi-work by using the atoi to convert the string to an integer for me but i still cant get it to do its job properly.

Code:

#include<iostream>
#include <string>
#include <sstream>
#include <algorithm>


using namespace std;

int main(){

    
     
int i=0, ii = 0, maxMovies;
int vvv[maxMovies];

string input;


char string[50]="place holder";

//command to prompt user for amount of movies
cout<< "How many movies do you want to add? ";
getline(cin,input);
//end command to prompt user for amount of movies

//set up loop situation to take the input from user and transfer it to X
stringstream(input)>> maxMovies;

//sets up array of however many X is with a limit of 50 characters
char movies[maxMovies][50];
char ratings[maxMovies][50];
int count[maxMovies];

system("cls");


while( i < maxMovies ){
                      
                       cout <<"Enter Movie # "<<i+1<<" : ";
                     
                       cin.getline(movies[i], 50);
                     
                       cout <<"Enter Rating: ";
                      
                       cin.getline(ratings[ii], 50);
            
                       system("cls");

                     
                       i++;
                       ii++;
                       
}


//converting rating in integer from string
int lo = 0;
int zztop = 0;
int zzjr = 0;
do  
{
 vvv[zztop] = atoi (ratings[zzjr]);
 zztop++;
 zzjr++;
 lo++;
                       
                       }
                       while ( lo <= maxMovies );
     //end conversion of integer from string
     
     
     int yu = 0;
     int zz = 0;
     int ily = 0;
     int zzd = 0;

while (vvv[zzd] < vvv[zzd + 1] )
{

        


       //strcpy (yu, vvv[zz]);
       yu = vvv[zz];
       vvv[zz] = vvv[zz+1];
       vvv[zz + 1] = yu;
        //strcpy (vvv[zz], vvv[zz+1]);
        //strcpy (vvv[zz + 1], yu);
      zz++;
      ily++;
      zzd++;
}


//test string copies from ratings[z] to ratings[z+1]
//int z = 0;
//strcpy (ratings[z + 1], ratings[z]);




system("pause");


system("cls");
cout << "Results Are As Follows :" << endl << endl;

i = -1 ;
ii = -1;


for ( int z = 0; z <= maxMovies - 1;)
{
      i++;
      ii++;
      cout << movies[i] 
           << endl 
           << "Rating : " 
           << vvv[z] 
           << endl 
           << endl;

           z++;
}

   
cin.get();
return 0;
}

because now i am using

Code:

while (vvv[zzd] < vvv[zzd + 1] )
{

        


       //strcpy (yu, vvv[zz]);
       yu = vvv[zz];
       vvv[zz] = vvv[zz+1];
       vvv[zz + 1] = yu;
        //strcpy (vvv[zz], vvv[zz+1]);
        //strcpy (vvv[zz + 1], yu);
      zz++;
      ily++;
      zzd++;
}

and still it only swaps the first 2 variables if needed but disregards the rest, and sorry but i dont understand your post it looks swell and im sure it works better but i cant understand it to the fullest so it doesnt help me as much sadly.
