Fstream derived, Array-driven search.

[JBL]

Hey guys, I have recently taken a class in C++ as part of my program for a degree in Computer Science. I was given the task of supplying an array with data through file and file manipulation by my oh-so-lovely lecturer.

My code looks like this:

//including pre-processor directives               
#include <iostream>
#include <fstream>

//make use of the C++ standard libraries
using namespace std;

int main()
{
    //declaring and initializing variables
    ifstream bobCat;
    string code = "";
    string firstName[25] = {""};
    string lastName[25] = {""};
    string catBob[25] = {""};
    string ans = "";
    
    //openning text file and attenuating it to object
    bobCat.open ("Advanced27.txt", ios::in);
    
    //affixing the data from the file to the three array indices
    for (int count = 0; count <= 24; count++){ 
    
    getline(bobCat, catBob[count], '#');
    bobCat >> firstName[count];
    bobCat >> lastName[count]; 
    }
    
//    if (bobCat.is_open()){
       
 
 
    cout << "Welcome to Bobcat.exe. \n\n";
    
    while (code != "Z3"){
          cout << "If you would like to begin an employer search "
          << "please enter: \n\n|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-"
          << "|-|-|-|-|-|-|-|-|\n"
          << "| - F1 -> for Full-time employees who sell new cars.| "
          << "\n| - F2 -> for Full-time employees who sell old cars.|"
          << "\n| - P1 -> for Part-Time employees who sell new cars.|"
          << "\n| - P2 -> for Part-Time employees who sell old cars.|"
          << "\n| - or Z3 -> to end Bobcat.exe                      |\n"
          << "|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|\n";
          
          cin >> code;
          
          while (code != "F1" && code != "F2" && code != "P1" && code != "P2" && code != "Z3"){
          
          //if (code != "F1" && code != "F2" && code != "P1" && code != "P2" && code != "Z3"){
             cout << "ERROR 101: Unsuitable Code Transaction...\n "
             << "Please try again.\n\n";
             
             cout << "If you would like to begin an employer search "
             << "please enter: \n\n|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-"
             << "|-|-|-|-|-|-|-|-|\n"
             << "| - F1 -> for Full-time employees who sell new cars.| "
             << "\n| - F2 -> for Full-time employees who sell old cars.|"
             << "\n| - P1 -> for Part-Time employees who sell new cars.|"
             << "\n| - P2 -> for Part-Time employees who sell old cars.|"
             << "\n| - or Z3 -> to end Bobcat.exe                      |\n"
             << "|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|\n";
          
             cin >> code;
             
          //} 
          
          //}
          
          while (code == "Z3"){
             cout << "Are you sure you want to quit BobCat.exe?\n"
             << "Please type yes to continue or no. \n\n";      
             cin >> ans;
                   
             if (ans == "yes"){
                  cout << "Thank you for using BobCat.exe. Enjoy your day!";
                  code = "Z3";
                  break;
             }
                  
                  else if (ans == "no"){
                       cout << "If you would like to begin an employer search "
                       << "please enter: \n\n|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-"
                       << "|-|-|-|-|-|-|-|-|\n"
                       << "| - F1 -> for Full-time employees who sell new cars.| "
                       << "\n| - F2 -> for Full-time employees who sell old cars.|"
                       << "\n| - P1 -> for Part-Time employees who sell new cars.|"
                       << "\n| - P2 -> for Part-Time employees who sell old cars.|"
                       << "\n| - or Z3 -> to end Bobcat.exe                      |\n"
                       << "|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|\n";
          
                       cin >> code;
                       
                  }
                       
             
          }

               
          cout << "Employees of the " << code << " type include:\n";
               
          for (int countUp = 0; countUp <= 13; countUp++){
              
              if (catBob[countUp] == code){        
              cout << firstName[countUp] << " " << lastName[countUp] << "\n";
                 
                                  
                    }
              }  
          }
          }
          
    system("PAUSE"); 
    return 0;    
}

The program is supposed to search the array for information assigned to it by a loop and some file manipulation.

I expect to have the list of corresponding list to be printed when the user inputs a particular code but alas this does not occur.

The file, that my lecturer gave me to use for this particular project, has its information written like this:

F1#John James
P2#Mary Dapper
F2#Mary Jones
P1#Jeff Bride
F2#Joel Adkari
P2#Kristy Jacob
F1#June Joana
F1#Jacob Sueba
P2#Tammy Janes
F1#Charles Smith
P1#Bridget Hines
P2#Jerry Kramer
P1#John Adams
P2#William Smith
P1#Jenny Adair
F1#Connie Gray
F1#Chris Thomas
F1#Carl Angles
P2#Jenny Jonah
F1#Carol Verace
P1#Ann Jerame
P2#Kate Krumpet
F2#Janice Paulo
P1#Suman Cary
P1#Ann Patel

Unfortunately i only get as far as Joel James.

How can i correct my code? Thank you.

It appears that your problem is that the cin extraction operator>> is leaving the end of line character in the input buffer which is being extracted by the getline() and placed into the beginning of the string. So instead of having 2 characters you have 3 characters for your code for all but the first entry. Try placing a catBob.ignore() after you extract your last name.

Use of std::string objects requires the <string> header. If you can compile without this present then your implementation is bringing the header in when you include another header. You should not rely on this and explicitly include the <string> header.
