Sorting through a vector.

[chocolatepig]

Hey forum I am trying to create a function that searches through a vector to find a name. I want to use a loop to iterate through the vector then stop and display the location of the name. I am not sure how to start I was wondering if I could get some help, thanks.

I am also trying to create a remove name function that takes out a name from input but I am also not sure why it is not working.

 #include<iostream>
#include<stdlib.h>
#include<vector>
using namespace std;


char startMenu ();
void getNames (vector<string>& name);
void displayNames (vector<string>& name);
void sortNames ();
void findName (vector<string>);
void removeName ();


int main()
{
    startMenu();
    vector<string> name;
    getNames(name);
    sortNames(names);
    
	displayNames (name);

	
	
	
system("pause");
return EXIT_SUCCESS;
}

char startMenu()
{
     char option = 0;
     cout << "Please choose from the following list: " << endl;
     cout << "Enter names: 'e', display names: 'd', sort: 's', find: 'f', or remove: 'r'." << endl;
     cin >> option;
     return option;
}

void getNames(vector<string>& name) {
     vector<string> names;
     string tmp;
     while (true) {
       cout << "Enter a name (quit to stop): ";
       cin >> tmp;
       if (tmp == "quit") break;
       names.push_back(tmp);
       }
}

void displayNames (vector<string>& list)
{
	if (list.size() > 0) 
   {
       for (int n=0; n < list.size(); n++) 
       {
         cout << list[n] << endl;
       }
   }
       else cout << "No names stored." << endl;
}

void sortNames (vector<string>& names)
{
     sort(names.begin(), names.end());
}

void findName (vector<string>& list, name)
{
     cout << "Which name are you looking for?" << endl;
     do 
}

/*void removeName(vector<string>& list)
{
     if (list.size() > 0) {
       string name;
       int ndx;
       cout << "What name do you wise to remove?" << endl;
       cin >> name;
       ndx = findName (list, name);
       if (ndx >= 0) {
          list.erase(list.begin() + ndx);
          cout << name << " has been removed " << endl;
          } else cout << "The name you entered is not in the list." << endl;
                     
}*/

remove std:: prefix if you declared using namespace std;, and replace auto
with vector<string>::iterator if you have not enabled -std=c++0x

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

void findName( const std::vector<std::string>& list )
{
    std::string name;
    std::cout << "Which name are you looking for?" << std::endl;
    std::getline( std::cin, name );

    int index = 0;
    for( auto itr = list.begin();
            itr != list.end();
            ++itr,
            index++)
    {
        if( *itr == name )
        {
            std::cout << "Name found in position: " << index;
            break;
        }
    }
}

int main ()
{
    std::vector<std::string> name( 5 );
    // these are names of warcraft DOTA characters, in case your wondering :)))
    name[ 0 ] = "Raijin Thunderkeg";
    name[ 1 ] = "Nevermore";
    name[ 2 ] = "Kael";
    name[ 3 ] = "Mirana";
    name[ 4 ] = "Mortred";
    
    findName( name );
    
}

or easier, you can use find() from <algorithm>
