Problems with transform()

[pspwxp fan]

According the exercise, which makes us practice with vectors, i am supposed to write a program that allows the user to enter his/her favorite games, view them and remove any he likes. Obviously, to remove a piece of text, it has to be of the same case as the one entered by the user. So i had to use transform() from the algorithm include file to convert it.
Unfortunately, there seems to be a transform() in the vector include file too. And by the looks of it, my compiler is confusing the two with each other. Error generated is at the bottom. Heres the code i got:

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

using namespace std;

int main()
{
    vector<string> gameName;
    int choice = 0;
    string game = " ";
    vector<string>::iterator myIterator;
    vector<string>::const_iterator iter;

    cout<<"This allows you to maintain your favorate games \n to get started, press enter."<<endl;
    cin.get();
    cout<<"What do you want to do?"<<endl;
    cout<<"1: Add a game \n 2: Remove a game \n 3: View games \n 4: Exit"<<endl;
    cin>>choice;
    while(choice >= 1 && choice < 4){
        switch(choice){
            case 1:
                cout<<"Enter a new favorate game: "<<endl;
                getline(cin, game);
                transform(game.begin(), game.end(), game.begin(), tolower);
                gameName.push_back(game);
                break;

            case 2:
                cout<<"Enter the name of the game you wish to remove:";
                getline(cin, game);
                transform(game.begin(), game.end(), game.begin(), tolower);
                for(myIterator = gameName.begin(); myIterator !=  gameName.end(); myIterator++){
                    if(*myIterator == game){
                        gameName.erase(*myIterator);
                    }else{
                        cout<<"Invalid name; try again later"<<endl;
                    }
                }
                break;

            case 3:
                for(iter=gameName.begin(); iter != gameName.end(); iter++){
                    cout<<*iter<<endl;
                }
                break;
        }
        cout<<"What do you want to do?"<<endl;
        cout<<"1: Add a game \n 2: Remove a game \n 3: View games \n 4: Exit"<<endl;
        cin>>choice;
    }
    cin.get();
}

This gets rid of the error in visual studio 2008, but it doesn't mean
your program works. Try it :

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

using namespace std;

int main()
{
    vector<string> gameName;
    int choice = 0;
    string game = " ";
    vector<string>::iterator myIterator;
    vector<string>::const_iterator iter;

    cout<<"This allows you to maintain your favorate games \n to get started, press enter."<<endl;
    cin.get();
    cout<<"What do you want to do?"<<endl;
    cout<<"1: Add a game \n 2: Remove a game \n 3: View games \n 4: Exit"<<endl;
    cin>>choice;
	

    while(choice >= 1 && choice < 4){
        switch(choice){
            case 1:
                cout<<"Enter a new favorate game: "<<endl;
                getline(cin, game);
                transform(game.begin(), game.end(), game.begin(), tolower);
                gameName.push_back(game);
                break;

            case 2:
                cout<<"Enter the name of the game you wish to remove:";
                getline(cin, game);
                transform(game.begin(), game.end(), game.begin(), tolower);
                for(myIterator = gameName.begin(); myIterator !=  gameName.end(); myIterator++){
                    if(*myIterator == game){
						gameName.erase(myIterator);
                    }else{
                        cout<<"Invalid name; try again later"<<endl;
                    }
                }
                break;

            case 3:
                for(iter=gameName.begin(); iter != gameName.end(); iter++){
                    cout<<*iter<<endl;
                }
                break;
        }
        cout<<"What do you want to do?"<<endl;
        cout<<"1: Add a game \n 2: Remove a game \n 3: View games \n 4: Exit"<<endl;
        cin>>choice;
    }
    cin.get();
}

Ok the original post was about gcc, which has a tolower function that
does not return a char, it returns an int and takes an int. That is because it works with internationalized character sets. So you do a functional composite to convert the form both ways or just write a quick function like this (you can use a functor if you prefer).

char charLower(const char& P)
{ 
     return static_cast<char>(tolower(P));
}

transform(A.begin(),A.end(),A.begin(),charLower);

Additionally you do also need to remove the pointer redirection (the *) in the erase line gameName.erase(*myIterator); as pointed out by firstPerson. And once that is working you can start debugging.... Enjoy.

Did both. Added the function StuXyz gave at the beginning of my main.cpp.

It still doesn't work and no difference :(
