String Element Extraction

[coroche]

Hi, I'm trying to write a programme that will take user input strings containing name, surname and city of residence separated by spaces and extract each one and print them out individually.
Here's what I have so far.

#include <iostream>
#include <stdio.h>
#include <cstring>
using namespace std;

int main()
{
 char name[4][80];
 char buffer1 [80];
 char buffer2 [80];
 char buffer3 [80];
 int i,j,k,q,word_size,start_pos,end_pos,name_size,city_start,city_end,city_length;


 cout<<"Enter three names and cities of residance"<<"\n";
 gets( name[0]);
 gets( name[1]);
 gets( name[2]);

 cout<<"initialise check"<<"\n";


cout<<"\n";
cout<<"\n";
cout<< name[0]<< "\n";
cout<< name[1]<< "\n";
cout<< name[2]<< "\n"<<"\n";

  for (i=0; i<=2; i++)
  { j=0;

   while (isspace  (name[i][j]) )

     {j=j+1;

     }



         k=j;
         while(!isspace(name[i][k])) k=k+1; //advances through the first name
         name_size=k-j;

         for (q=0; q<name_size; q++)
          {
            // this generates the name
            buffer1[q] = name[i][j];
            j++;
          }


    buffer1[j]='\0';//this is the null char to terminate surname name
     cout<<"Name "<<i+1<<": "<<buffer1<<"\n";

         while(isspace(name[i][k])) k=k+1;   // advances through the next block of spaces
         start_pos=k;
         while(!isspace(name[i][k])) k=k+1;// advances through the surname
         end_pos=k;

         word_size= end_pos - start_pos;

     // check word size of first char



      for (q=0; q<word_size; q++)
          {
            // this generates the surname
            buffer2[q] = name[i][start_pos];
            start_pos++;
          }



    buffer2[start_pos]='\0';//this is the null char to terminate surname name

    cout << "Surname "<<i+1<<": "<<buffer2 << "\n";


    while(isspace(name[i][k])) k++;

    city_start=k;
    while(!isspace(name[i][k])) k++;

    city_end=k;
    city_length=city_end-city_start;


    for (q=0; q<city_length; q++)
          {
            // this generates the city
            buffer3[q] = name[i][city_start];
            city_start++;
          }



    buffer3[city_start]='\0';//this is the null char to terminate surname name
    cout<<"City "<<i+1<<": "<<buffer3<<"\n";
    cout<<"\n"<<"\n";

  }
    return 0;
}

This code is working to an extent but some of the results have extra characters at the end. Also you have to put a space after city in the input in order to stop counting "city_end". Is there any way around this?
Thanks

You can get input from the user using operator>> :

#include <iostream>
#include <string>

int main()
{
   std::string name1, name2, city;
   std::cout << "Enter names and city:" << std::endl;
   std::cin >> name1 >> name2 >> city;

   std::cout << "Hello, " << name1 << " " << name2 << " from " << city << std::endl;

   return 0;
}

Assuming you won't have any input like
Victor Von Doom St. Louis
Dick Van Dyke New Rochelle

Use 3 while loops and 1 index into the buffer.
First and Second while copies until a SPACE is seen
Third copies until a \0 is seen.

Could you elaborate a bit more on this please, I'm having the same problem.
