Higest and Lowest

i have a text file that i am reading from! This is what the text file looks like:-

01 633.79
02 2242.03
06 4587.12
08 2318.98
05 565.32
07 865.99
03 6591.96
04 1974.90
09 453.33

i have manager to read from the file and get it to display but now i need some code, so i can view just the highest or just the lowset!

if ( current > max ) max = current;

Just do that as you loop through your array of values.

i am not too sure what you mean because i am very new to c++! i only started doing it about 3 months ago! this is my university project! Maybe if i show you my code you might beable to giv me more help!

Code:

#include <iostream>
#include <fstream>

using namespace std;

int sales_data();  //Sales data function
int save_data();  // Save data function

int main()
{
    int num;
   
    cout << "MAIN MENU" << endl;        //Main Menu
    cout << "\nEnter a number between 1 and 3" << endl;
    cout << "\n-----------------------------" << endl;
    cout << "1. View Sales Details" << endl;
    cout << "2. Export and Save Sales Details" << endl;
    cout << "3. Exit" << endl;
    cout << "-----------------------------" << endl;
    cin >> num;


  switch(num)
  {
      case 1:
      system("CLS");
      sales_data();
      break;
      case 2:
      system("CLS");
      save_data();
      break;
      case 3:
      system("exit");
      break;
      default:
      cout << "Incorrect Number" << endl;
      break;
  }
}

int sales_data()
{

  int num;
 
  int depid;    //Department ID numbers
  double sales; //Sales Figures
 
  ifstream salesfile ("ica_sales.txt");  //Open sales file
        if (salesfile.is_open())
        {         
        cout << "SALES DATA\n" << endl;         
        while (! salesfile.eof() )
        {     
        salesfile >> depid >> sales;
        cout << depid << "\t" << sales << endl; //Output department IDs and sales figures
        }
        salesfile.close();
        }
        else cout << "Unable to open file" << endl; 
 
  cout << "\nSALES MENU" << endl; // Sales Menu
  cout << "\nEnter a number between 1 and 4" << endl;
  cout << "\n-----------------------------" << endl;
  cout << "1. View Highest Department" << endl;
  cout << "2. View Lowest Department" << endl;
  cout << "3. Back to main" << endl;
  cout << "4. Exit" << endl;
  cout << "-----------------------------" << endl;
  cin >> num;

  switch(num)
  {
      case 1:
     
      break;
      case 2:
      break;
      case 3:
      system("CLS");
      main();
      break;
      case 4:

      break;
      default:
      cout << "Incorrect Number" << endl;
      break;
  }
  return 0;
}

int save_data()
{
    int num;
   
  cout << "Enter a number between 1 and 4" << endl;
  cout << "-----------------------------" << endl;
  cout << "1. Dont no what i need in here yet!!!" << endl;
  cout << "2. Back to Main" << endl;
  cout << "3. Exit" << endl;
  cout << "-----------------------------" << endl;
  cin >> num;

  switch(num)
  {
      case 1:
      break;
      case 2:
      system("CLS");
      main();
      break; 
      case 3:
      system("exit");
      break;
      default:
      cout << "Incorrect Number" << endl;
      break;
  }
  return 0;
}

> salesfile >> depid >> sales;
Maybe create a struct containing deptID and sales?

Maybe create an array of that struct and read the file into that array (or better yet, use a std::vector)

You're behind the curve IMO if you don't know about structures and arrays after 3 months.
